High-Throughput Meets High-Stakes 

Led by Christina Ferreira at Purdue’s Bindley Bioscience Center, the team developed a high-throughput workflow that screens and analyzes PFAS-like compounds hundreds of times faster than traditional methods. The platform relies on high-throughput desorption electrospray ionization mass spectrometry (HT DESI-MS), a rapid-fire analytical tool that screened over 1,000 reactions in just hours, generating 915 novel PFAS-like molecules with minimal waste output. 

This method drastically reduces the typical time and cost associated with chemical screening, allowing you to evaluate the reactivity, degradability, and structural profiles of a wide chemical library in seconds. Ferreira’s team also incorporated computational modeling to predict environmental persistence and toxicity, bridging the gap between chemical design and ecological impact. 

Why It Matters 

PFAS are notoriously resilient, and traditional water treatment infrastructure isn’t designed to handle their stability. What this Purdue development offers is a front-end solution that rethinks PFAS at the design level before they become another contaminant to remove downstream. 

This platform helps identify “non-regrettable” alternatives to current PFAS compounds used in industrial and consumer products. That matters for regulatory compliance, future liability, and sustainability goals. The system also lays the groundwork for new cleanup strategies by making it easier to understand how modified PFAS degrade—or don’t—in various environments. 

Tech Transfer and Practical Adoption 

Purdue has filed for a U.S. patent and is actively seeking commercial partners. While this technology isn’t plug-and-play for operators just yet, it signals what’s coming. Tools like this could integrate into upstream product development, contamination risk assessment, or even real-time PFAS monitoring and response systems down the line. 

For those working on source control, treatment technology development, or PFAS-specific remediation efforts, this method adds a powerful piece to the puzzle that’s faster, smarter, and more predictive chemical evaluation. 

This is a potential turning point. With regulators tightening standards and communities demanding action, tools that can accelerate the replacement and breakdown of PFAS are critical. If adopted at scale, this kind of rapid screening could finally give you a head start on PFAS instead of constantly playing catch-up.

This week, Water Treatment 411 takes a closer look at how this new grant could support rural PFAS response. 

Why Small Systems Are Uniquely Vulnerable 

Many rural systems operate with a skeleton crew. One operator may handle everything from compliance to maintenance. Adding fuel to the fire, their facilities, often decades old, weren’t designed with PFAS in mind, and the contaminants’ chemical resilience (especially short-chain varieties) demands treatment processes that weren’t even on the radar when these systems were built. 

Treatment retrofits introduce new complexities. Choosing between granular activated carbon, ion exchange, or reverse osmosis isn’t straightforward without solid data. And costs don’t end with installation. There’s also media replacement, pretreatment, disposal, and ongoing operations that require resources that many small systems simply don’t have. 

Tighter future regulations on the horizon will only complicate matters. A system may invest in treatment this year, only to be out of compliance by the time the next rule is finalized. The financial risk of making the wrong call is real. 

What the Grant Actually Covers 

This grant won’t pay for a new treatment plant, but it will help communities understand what they’re up against. Key focus areas include: 

• Sampling and exposure assessment 

Many systems still lack baseline data. The grant supports statistically valid testing to identify contamination sources. 

• Technical assistance and operator training 

This includes education on PFAS-specific treatment challenges, financial planning, and even cybersecurity readiness. 

• Planning support 

This will help systems evaluate treatment options, prepare for future rules, and identify funding mechanisms like state revolving funds. 

• Capacity-building tools 

Grants can support the use of EPA’s Water ICAT to assess and plan infrastructure and compliance efforts. 

The grant essentially funds the homework. It’s not the solution, but it prepares systems to choose the right one before being forced into costly emergency compliance. 

Implications Beyond PFAS 

Though branded as a PFAS initiative, the grant reflects a broader pivot in federal water policy: less emphasis on hardware, more on systemic capacity. The EPA’s direction here suggests future funding will increasingly be tied to demonstrated readiness, planning, and managerial strength. This grant offers a chance to establish that credibility now. 

It’s worth noting that private wells and decentralized systems are also included. That opens the door for rural professionals to lead coordination efforts, even beyond their own system boundaries. Understanding PFAS risk in the broader watershed or aquifer could soon become part of the job description. 

What You Should Be Doing Now  

• Update sampling protocols 

Get a statistically valid PFAS baseline while grant funds are available. 

• Model long-term costs 

Factor in not just installation, but media replacement, waste disposal, and maintenance. 

• Train and cross-train staff 

Use grant-backed training to fill skill gaps and prepare for future treatment needs. 

• Plan funding pathways 

Align projects with state revolving fund cycles or Infrastructure Investment and Jobs Act (IIJA) opportunities. 

• Benchmark system readiness 

Tools like Water ICAT can help you map risks, funding needs, and priority upgrades. 

Without the right information, skills, or financial planning, even well-intentioned efforts for PFAS treatment can miss the mark. This EPA grant gives professionals a rare chance to prepare. 

The funds aren’t enough to solve our PFAS crisis outright, but they offer a practical on-ramp to compliance. Use this window wisely. Acting early enables even the smallest communities to be ready.

To make real progress in predictive maintenance, resource efficiency, and public safety, utilities must get serious about their data quality. This week, Water Treatment 411 tackles exactly where to start to do just that. 

Old Meters, New Problems 

Metering, the backbone of many water systems, hasn’t kept up with the pace of digital advancement. Legacy meters, often decades old, are prone to failure and frequently generate inaccurate readings. This becomes a compounding issue when utilities still rely on manual logging methods. Even a small inconsistency, if repeated across a network, can throw off usage data, system maps, and leak detection efforts. 

Smart meters can solve part of this, but not without a strategy for integration, data storage, and ongoing calibration. Simply swapping hardware won’t improve decision-making if the incoming data isn’t processed correctly or aligned with existing systems. 

Human Error and Siloed Systems 

Field data collection remains highly manual in many facilities. This introduces inevitable human error, especially when multiple departments work in silos with incompatible software platforms. This can result in duplication, inconsistent formats, and unreliable system-wide analytics. 

Standardizing data management protocols and centralizing data access are essential first steps. Water utilities that succeed in this area often appoint dedicated data stewards or analysts who oversee quality control and ensure data flows consistently across teams. 

Infrastructure Leaks as Data Gaps 

Leaks distort the data that utilities depend on to measure system health. A missed leak becomes a phantom anomaly in flow models. Aging pipes or poorly maintained valves that allow unmeasured losses undermine everything from demand forecasting to asset management. 

Addressing this means investing in sensors that can detect pressure drops, temperature shifts, or flow irregularities in real time. But even more critical is having analytics in place that can interpret these signals and trigger timely interventions. 

The Weakest Link in Data Integrity 

Water utilities are now high-priority targets for cybercriminals, especially hacktivists and ransomware groups. As recent breaches have shown, the absence of basic controls like multi-factor authentication and password hygiene has left water systems dangerously exposed. 

Cybersecurity is no longer optional. Staff need real-world training on digital threats, and IT teams must routinely audit systems and patch vulnerabilities. If you’re adding new smart devices or remote monitoring tools, each one must be treated as a potential attack vector and secured accordingly. 

AI and Automation 

There’s strong interest in using AI to predict leaks, schedule maintenance, or analyze usage trends. But machine learning is only as good as the data you feed it. Before bringing AI into your facility, make sure your existing data is structured, labeled, and cleaned. Don’t skip this step. AI won’t fix data quality. It will only amplify your mistakes at scale. 

Build the Right Culture  

Technology alone won’t solve your data problems. You need a workforce that understands why data matters. Leadership must set expectations around data hygiene, accurate reporting, and interdepartmental communication. Incentives can help, but long-term improvement depends on consistent messaging: Clean data makes everyone’s job easier and improves outcomes across the board. 

Better Data, Smarter Decisions 

Accurate, standardized, and secure data gives you control. And it’s not just about your operations. Communities rely on you for clean, safe, affordable water. The better your data, the better your ability to deliver on that promise. 

Start by assessing your weakest points: meter accuracy, entry protocols, siloed databases, or cyber vulnerabilities. Then prioritize improvements that give your team clearer insights and faster responses. The tools are available, but the execution is up to you.

When BAC Stops Pulling Its Weight 

BAC has become a cornerstone in advanced treatment trains for good reason. It’s effective at removing a broad range of organics, including hard-to-treat micropollutants like iopamidol (IPM), while also providing biological degradation of organics that pass through ozonation or other pre-treatments. But as BAC media ages, performance degrades, not just from spent carbon but from heavy microbial colonization, extracellular polymeric substance (EPS) buildup, and pore blockage. Older BAC (up to 10 years in some DWTPs) can become so loaded with biomass and adsorbed compounds that even aggressive backwashing offers minimal performance recovery. 

Traditional regeneration options like thermal reactivation or solvent-based methods are either too energy-intensive or impractical for BAC due to its biological component. Previous attempts using ultrasonic or basic thermal techniques yielded limited success. Enter thermally activated persulfate, a promising oxidant that’s gaining attention for its effectiveness and simplicity. 

How Thermal PS Cleans House 

This study categorized the PS regeneration process into three distinct stages: 

1. Microbial Inactivation and Biofilm Detachment 
   Over 95% of the microbial population was eliminated during the initial phase. Laser scanning confocal microscopy confirmed biofilm disintegration, especially in the outer layers. This step alone addresses a major root cause of BAC fouling. 

2. Oxidation of Surface-Exposed Adsorbates 
   With biofilm cleared, PS oxidizes pollutants adsorbed to exposed carbon surfaces. The study found increased soluble microbial products (SMPs) in the rinse water, particularly macromolecular compounds in the 2,000–50,000 kDa range, indicating breakdown of complex organic matrices. 

3. Carbon Skeleton Oxidation and Deep Impurity Removal 
   Final-stage oxidation targeted deeper impurities and partially restored pore structures, though micropore recovery remained under 5%. Despite this, surface functionality and adsorption capacity saw substantial improvement, especially for younger BAC. 

Regeneration effectiveness was closely tied to media age, with 3-year-old BAC recovering 72.6% of its adsorption capacity versus just 27.4% for 10-year-old media, reinforcing that thermal PS is best used as a preventative strategy before BAC exceeds 5 years in service. 

Is This Ready for Plant-Scale Rollout? 

While the lab-scale results are promising, scale-up challenges remain. The study doesn’t address full-scale contact times, PS dosing logistics, or thermal energy requirements in continuous flow systems. However, compared to UV-activated or iron-activated PS systems, thermal activation is far more practical for most facilities. No special catalysts. No complex irradiation setups. Just heat and oxidant. 

Operators considering implementation will need to evaluate: 

• Compatibility with existing filter vessels for heating 

• Neutralization of PS residuals post-regeneration 

• Handling of regeneration byproducts, particularly SMPs and partially oxidized organics 

A Tool, Not a Silver Bullet 

Thermally activated PS is not a cure-all, with effectiveness depending heavily on timing and media age. But for utilities looking to extend BAC life, improve pollutant removal, and reduce costs associated with premature media replacement, this method offers a promising middle ground. It’s especially attractive in utilities with limited GAC disposal options or high replacement costs. 

The science is sound, the results are measurable, and the process is relatively straightforward. For medium-aged BAC, the benefits are substantial. For heavily fouled media, it might be too little, too late. Either way, it’s time to start thinking about BAC not as disposable, but as regenerable — with the right chemistry.

The Silent System Killer 

As solids content increases, so does viscosity. That might seem obvious, but the relationship between viscosity and operational performance is often underestimated. Wastewater, sludge, digestate, and manure behave differently depending on shear stress, temperature, and solids load. That makes them non-Newtonian fluids that constantly change in response to how you process them. High-viscosity sludges not only require more energy to pump, they foul equipment faster and resist efficient heat transfer. 

If you’re still using the same heat exchanger design across different waste streams, you’re likely leaving efficiency and budget on the table.  

Corrugated Tubes: The Workhorse Solution 

For mid-range viscosities, corrugated tube heat exchangers are a smart upgrade. Their internal surface disrupts flow in a way that reduces fouling and increases turbulence. That means better thermal transfer and longer cleaning intervals. You also get lower pressure drops, which minimizes pump load and energy demand. 

Systems that use corrugated tubes can strike a balance between performance and maintenance. If you’re dealing with sludges that have enough flowability but still risk clogging smooth tubes, this design is worth a closer look. 

Double-Tube Designs: When Solids Are Suspended, Not Settled 

If your stream has lower viscosity but is packed with suspended solids, such as early-stage sludge or mixed wastewater, double-tube exchangers offer a wide-bore option. Larger flow paths reduce blockage risk, and removable inner tubes simplify inspection and cleaning. For facilities focused on energy recovery, double tube heat exchangers integrate easily with CHP heat loops, boosting your thermal ROI. 

Scraped Surface: The Only Option for Ultra-Viscous Wastes 

There’s a threshold where corrugated or tube-in-tube exchangers just can’t cope. When dealing with ultra-viscous materials such as food waste slurries, thick digestate, or evaporation concentrates, scraped surface heat exchangers (SSHEs) become essential. 

These systems use a reciprocating scraper mechanism to physically remove fouling during operation, keeping heat transfer rates high, even during evaporation. The scrapers also promote mixing, helping maintain flow, and prevent hotspots or solids buildup. 

In evaporation setups, SSHEs can operate continuously in multi-effect arrangements, integrating with mechanical vapor recompression (MVR) or vacuum systems. You get consistent concentration performance with less downtime and maintenance. 

Digestate Concentration: Closing the Loop on Water and Waste 

Anaerobic digestion leaves behind a watery byproduct that’s costly to store, transport, or spread. But concentrating that digestate, without adding energy overhead, is now more achievable with systems that can leverage existing CHP heat and vacuum evaporation. Some setups use cyclone separators and multi-stage steam reuse to keep the process closed-loop, feeding condensate back into the digester as dilution water. The outcome is a higher-solids concentrate with more recoverable nutrients and a much smaller volume footprint. For plants looking to tighten up water reuse and cut hauling or storage costs, this kind of integration is increasingly hard to ignore. 

Match Your Heat Exchanger to Your Waste 

Selecting the right heat exchanger design isn’t just about specs on paper. You need to account for the changing nature of viscous waste, how it behaves under stress, and what your operational goals are, whether that be concentration, energy recovery, or just reliable thermal processing. 

If your sludge is relatively fluid, under 50 cP, and your main goal is heating, a corrugated or double-tube heat exchanger is likely to be sufficient. These designs can handle moderate solids and flow variability without the complexity of more advanced systems. Once viscosity climbs past 100 cP, or you’re concentrating and solids begin to settle, scraped suSSHEs) become the better choice. Their built-in cleaning mechanisms keep heat transfer surfaces functional under conditions that would foul other designs quickly. 

Beyond matching viscosity to exchanger type, consider practical factors like cleaning intervals, maintenance access, and how often you can afford downtime. Capital cost matters, but it shouldn’t outweigh lifecycle performance. Always ask for data and request case studies with conditions similar to your own. If your plant already generates surplus heat through a CHP system, leveraging that waste energy can tip the ROI in favor of more robust or multi-stage exchanger setups. 

When in doubt, test performance on-site or pilot a small-scale system. The capital cost of upgrading to the right exchanger is often offset quickly by reduced energy use, downtime, and maintenance. The right exchanger could just turn your sludge into an asset.

Why Stokes’ Law Doesn’t Cut It Anymore 

In theory, Stokes’ Law gives you a clean equation to calculate settling velocity based on particle diameter and fluid properties. In practice, it oversimplifies reality. Real-world flocs are irregular, porous, and highly variable. Their drag characteristics can change based on internal structure, coagulant chemistry, and flow regime. Empirical tweaks help, but they don’t generalize well across different systems. 

This is where machine learning has made inroads, offering better prediction by finding patterns in messy data. But ML models, especially neural networks, are black boxes. They give you results, but no insight. That’s not good enough for engineers tasked with justifying design decisions or meeting regulatory scrutiny. 

Enter Fuzzy Symbolic Regression 

Researchers Adriano Bressane et al. introduced a Physics-Informed Machine Learning approach using fuzzy symbolic regression (PIML-SR) to solve this exact problem. Their method starts with physical fundamentals like drag force and Reynolds number, incorporates detailed floc morphology from high-speed imaging, and applies fuzzy-enhanced symbolic regression to generate a compact, interpretable equation that reflects real-world behavior. 

Symbolic regression, using evolutionary algorithms to generate human-readable formulas from data, isn’t new. But combining it with fuzzy logic is. This approach lets the model gracefully handle uncertainty and non-linear transitions between flow regimes. It also embeds physical constraints so the equations remain grounded in reality. 

Why This Matters to You 

The team tested the approach on alum-kaolinite flocs and achieved near-perfect prediction accuracy (R² > 0.99) with extremely low error margins. Compare that to a traditional symbolic model (R² ≈ 0.56) or a neural network (R² ≈ 0.63) and the advantage is quite clear. Even a physics-informed neural net failed badly (R² ≈ -1.93), proving that interpretability plus physical knowledge beats black-box sophistication. 

From a plant operations or engineering standpoint, this kind of tool could reshape how you approach sedimentation design. It means smarter tank sizing, more reliable coagulant optimization, and better scaling from lab tests to full-scale systems. It also supports sustainability goals by fine-tuning processes that reduce chemical use, energy consumption, and sludge production. 

Caveats and Considerations 

Of course, no model is universal. This one was trained on specific lab-scale conditions with alum flocs, controlled pH, and laminar flow. Applying it in full-scale systems or with different coagulants will require either re-training or validation. But the framework itself is adaptable, and the potential for generalization is high, especially as more datasets are incorporated. 

What Comes Next 

This work sets the stage for broader use of physics-informed ML in water treatment. Imagine AI models that can predict filter head loss, sludge blanket stability, or floc breakage. And all with explainable outputs! As the industry leans into digital transformation, having interpretable, high-fidelity models will be key to both innovation and regulatory acceptance. 

If you’re working on optimizing sedimentation or just tired of the guesswork with floc behavior, it’s worth keeping an eye on where this research goes next. The tools are becoming smarter. And finally, they’re speaking the same language as engineers.

This week, Water Treatment 411 dives into what this policy means for water treatment professionals and why your role in shaping, supplying, and supporting these strategies is more critical than ever. 

From Permit Gatekeepers to Water Strategy Partners 

Facilities planning to withdraw large volumes of municipal water are facing new hurdles. Regulators now want to see where the water will go, how much will be used over time, and what measures are in place to minimize waste. But they’re not just asking industrial applicants. They’re implicitly asking you — your treatment engineers, plant managers, and water quality professionals — for the solutions. 

Whether it’s designing for reclaimed water integration, setting up closed-loop recycling for rinse and cooling cycles, or helping clients meet rising disclosure demands, treatment providers are now deeply embedded in the permitting and planning process. 

Why Reuse Isn’t Optional Anymore 

Water reuse has long been good practice. Now, it’s becoming a compliance requirement. In drought-prone or high-growth regions like Arizona, California, and Texas, there’s mounting pressure on municipal systems. Not to mention growing scrutiny on how much water industrial users are drawing. 

Your facility’s ability to treat, recycle, and reallocate water has direct implications for clients’ regulatory standing. This creates opportunities to offer more advanced services, from pretreatment design to decentralized reuse systems, all the way to data reporting support. 

Reclaimed Water Is a Resource, Not a Footnote 

Many cities already offer access to reclaimed water for non-potable industrial use, but uptake remains limited. For water treatment professionals, there’s a clear role in helping industrial clients switch to reclaimed sources, especially for operations like cooling or irrigation that don’t require high-purity water. Supporting this shift requires technical design, pipeline integration, quality monitoring, and, increasingly, regulatory navigation. 

Data Is the Next Utility 

As part of Tucson’s ordinance, industrial applicants must submit detailed usage projections and conservation strategies. This points to a broader shift of cities wanting numbers, forecasts, and measurable outcomes. 

Water treatment facilities are well-positioned to support this demand by offering more than just treatment capacity. Facilities that can provide reliable data on flow rates, recovery percentages, and system efficiencies will become indispensable partners in the development pipeline. 

What This Means for You 

Tucson’s policy reflects a growing trend where municipalities see water as a limited, shared resource and expect industrial development to be both transparent and efficient in how it uses it. For the water treatment industry, this shifts the value proposition from operational support to strategic partnership. 

Expect more involvement in the early phases of project planning. Expect to be consulted not just for what your system can handle, but for how it can prove conservation, enable reuse, and meet long-term sustainability metrics. If your team isn’t already building toward advanced reuse, integrated data systems, and compliance alignment, now’s the time. Before it’s too late.

This week, Water Treatment 411 explores the latest developments in DBP control and what they mean for your treatment strategy. 

Chloronitramide Anion: A New Compound in the Spotlight 

One of those question marks now has a name. Thanks to improved analytical techniques, researchers recently identified a previously unknown byproduct of monochloramine treatment: the chloronitramide anion (Cl–N–NO₂⁻). First detected decades ago but not speciatable at the time, this compound is now drawing increased attention. 

Its toxicology remains uncharacterized, but that uncertainty alone is a red flag. With the EPA historically cautious in the face of unknowns, expect that if chloronitramide is confirmed as hazardous, it will trigger regulatory and treatment responses across the industry. Operators would be wise to follow developments here closely. 

Why Organic Load Still Rules the Game 

The core issue remains unchanged: DBP formation correlates directly with the amount of total organic carbon (TOC) present before disinfection. Whether you’re dosing chlorine or monochloramine, the organics are the fuel. The less TOC, the fewer DBPs, known or unknown. 

That puts the spotlight squarely on upstream organic removal. While some treatment plants lean heavily on disinfectant choice, pre-disinfection TOC removal offers the most scalable, future-proof approach to minimizing DBPs regardless of the oxidant in use. 

PAC vs GAC: Know When to Deploy What 

Two main tools are on the table for removing organics before disinfection: powdered activated carbon (PAC) and granular activated carbon (GAC). The best option depends on system conditions and the variability of contamination. 

PAC is ideal for intermittent spikes. Think seasonal geosmin or MIB events. It’s applied like any other chemical dose and removed during coagulation and sedimentation. It’s cost-effective, flexible, and quick to implement. But it’s not optimized for constant load. 

GAC, with its fixed-bed configuration, is built for long-haul performance. Its upfront capital costs are higher, but operational costs can be lower over time due to deeper utilization of media capacity. If you’re facing sustained organic contamination, GAC typically makes more economic and operational sense. 

What to Watch For: Future DBP Regulation and Treatment Shifts 

DBP regulation is anything but static. The EPA’s Stage 1 and Stage 2 rules were major drivers behind monochloramine adoption, and further rules could target additional byproducts, especially if the chloronitramide anion proves harmful. That would potentially lead to new MCLs and changes in disinfection strategy, carbon application, or even source water management. 

Utilities that treat TOC reduction as optional are gambling with regulatory lag. Those proactively investing in upstream control, especially through scalable, media-based solutions, will be better positioned when the next round of DBP scrutiny arrives. 

Disinfectant selection matters, but organics control is what truly limits DBP formation. With monochloramine now under its own microscope, a renewed focus on pre-disinfection TOC removal could offer both compliance resilience and operational stability in an uncertain regulatory future.

Restoring safe water service is critical, but managing the public narrative is now just as important. If your media response plan isn’t locked and loaded, you’re already behind.  

This week, Water Treatment 411 lays out what you need to know before the unthinkable happens at your facility. 

Build the Brief Before the Emergency 

Don’t wait until you’re in the middle of a crisis to figure out what to say. Your team should have a standing media brief that’s updated quarterly and ready to deploy. This should include a plain-language explanation of what a BWA is, recent water quality benchmarks, contact details for designated spokespeople, and an FAQ section addressing common concerns like drinking safety, cooking, and pet use. Have draft language prepared for web updates, press releases, and social posts. When time is critical, this blueprint will become your communication command center. 

Technical Precision Can Wait 

Water professionals tend to default to technical language, but during a BWA, clarity beats jargon every time. The public doesn’t understand “chlorine residual non-compliance” or “fecal coliform exceedance.” They want to know: Is it safe to drink the water? How long will this last? Why did it happen? Translate your data into real-world meaning. Say “the water showed signs of contamination” or “we’re working to fix the source and will update you by tomorrow morning.” Plain language communicates control and competence, which is exactly what your community needs in a crisis. 

System-Structured Responses 

Just as your plant follows process flows and SOPs, your communications response should be built into a replicable workflow. Identify the moment an advisory is triggered, define who approves the language, and map out where and how messages are released. Coordinate internal updates, press releases, social media, and hotline scripts so all channels speak with one voice. Set a regular update cadence, even when there’s nothing new to report. Silence leaves room for speculation, but consistency builds confidence. 

Help Journalists Help You 

When reporters are under pressure, clear information becomes currency. Craft your updates like mini-news stories: a direct headline, a few key facts (who’s affected, what to do, when it might be resolved), and a quote from your team that can be reused without editing. Provide links to additional resources, such as maps, flyers, or testing data, so journalists don’t need to chase you down. A well-packaged update reduces the risk of being misquoted or misunderstood. 

Consistency Is Non-Negotiable 

One of the fastest ways to lose public trust is through conflicting information. If your hotline gives one answer, your social media says something else, and the local news reports a third version, confusion sets in fast. Prevent this by aligning all communication assets under a single source of truth. Draft core messaging that gets pushed to every platform at the same time. Train staff, especially frontline communicators, to stick to approved language and redirect questions when needed. 

Run Communication Drills 

Emergency exercises shouldn’t stop at operational response. Once per quarter, run a tabletop drill focused entirely on your communications plan. Simulate a real-world BWA, complete with press inquiries, customer complaints, and social media noise. Assign roles, practice message drafting, and stress-test your information release workflow. These dry runs will expose weak spots before a real event turns them into real failures. 

Don’t Vanish After the Advisory Ends 

When the all-clear comes, don’t just shut the lid and move on. Close the loop with your community. Use the same channels to announce the end of the advisory, explain what went wrong in plain terms, and share what was done to fix it. If applicable, mention any new monitoring, equipment upgrades, or changes made to prevent recurrence. This final communication step rebuilds public trust and shows accountability. A short follow-up survey can also provide useful feedback for future improvements. 

Media-Readiness: Now Part of the Job 

Water professionals have long mastered treatment processes, compliance metrics, and emergency response. But today, media readiness is also part of the toolkit. Being able to act fast, speak clearly, and communicate with consistency only adds to your operational resilience. And in an era of rising advisories and real-time public scrutiny, a response plan that covers all your bases is worth its weight in gold.

This week, Water Treatment 411 dives into a new solution from RMIT University that aims to stop the problem at its source. 

A New Take on Grease Interceptors 

Traditional grease traps remove only about 40% of fats, leaving emulsified and finer particles free to pass through. A research team at RMIT University’s WETT Research Centre came up with a solution that introduces physical baffles to slow wastewater, separating out larger particles more effectively. It then applies a small dose of alum to coagulate suspended and emulsified fats, which are otherwise the most difficult to capture. 

When tested in real-world conditions, along with high temperatures, strong detergent use, and genuine commercial kitchen effluent, the system removed up to 98% of fats. That’s more than double the efficiency of current approaches. 

The design is scalable for kitchen sizes ranging from small restaurants to large food processing facilities. It can also be retrofitted to existing grease management systems, a factor that significantly lowers barriers to adoption. 

Cost, Compliance, and Public Health Benefits 

For utilities, the implications go beyond saving on sewer maintenance. Sewer blockages create overflow events that directly increase regulatory exposure and public dissatisfaction. Preventing FOG at the source reduces spill risks and associated cleanup costs. 

For food service operators, the system offers a compliance advantage. Many municipalities are tightening FOG discharge standards, and technologies like this could help businesses stay ahead of enforcement while minimizing maintenance of their own plumbing. 

For public health, reducing sewage overflows lowers the likelihood of untreated wastewater reaching streets, rivers, and coastal waters. 

Integration and Next Steps 

The RMIT team is not treating this as a one-off invention. The technology is part of a broader suite being developed with partners including South East Water, Barwon Region Water Corporation, Queensland Urban Utilities, and ACO. Their next phase focuses on optimizing interceptor fluid dynamics to maximize FOG removal without relying on chemical dosing. 

That direction matters for long-term sustainability. While alum is cost-effective and widely used in treatment, minimizing reliance on coagulants aligns with utility goals to reduce chemical inputs where possible. If fluid dynamics optimization proves successful, future interceptors could be even more efficient, chemical-free, and maintenance-light. 

What This Means for You 

This development highlights two key takeaways. First, prevention at the source remains one of the most cost-effective strategies for infrastructure protection. Fatbergs are expensive to remove, but preventing them is comparatively cheap. Second, partnerships between researchers, utilities, and technology providers are accelerating solutions that are immediately practical. 

Stay tuned to Water Treatment 411, and keep an eye out on the rollout of these technologies. Widespread adoption in the food service sector could significantly reduce FOG load on wastewater systems, freeing up resources for utilities to focus on other pressing challenges like emerging contaminants or climate-driven system resilience.
