Wastewater Treatment Resources

  1. Beyond Clarification: Optimizing Polyacrylamide Selection For High-Complexity Industrial Wastewater Treatment 4/21/2026
    Polyacrylamide (PAM) selection in industrial wastewater treatment is frequently reduced to a trial-and-error exercise, resulting in reagent waste, inconsistent effluent quality, and inflated operating costs. This article presents a structured framework for PAM optimization across three critical variables — ionic charge density, molecular weight, and coagulant synergy.
  2. Beyond Clarifiers: How Advanced Primary Filtration Solves Wet Weather Capacity Challenges 4/16/2026

    Pile cloth media filtration treats wet weather flows in real time, increasing capacity, improving removal efficiency, and helping utilities reduce reliance on limited stormwater storage.

  3. Precision Control In The Aeration Basin: A Case Study In Flow-Based DO Stabilization 4/14/2026

    Flow-based DO control and advanced blowers help stabilize aeration, reduce energy consumption, and improve treatment performance, turning a major wastewater cost center into an efficiency opportunity.

  4. The Evolution Of Efficient Biosolids Solutions 4/13/2026

    Modern biosolids management requires sophisticated biological treatment to achieve Class A pathogen reduction and efficient solids destruction. Explore how integrated aerobic digestion and nutrient management technologies provide reliable, cost-effective paths toward regulatory compliance.

  5. The Pragmatic Shift In Source Water Protection: Moving From Symptom Management To Root-Cause Accountability 4/9/2026
    A shift in how we approach source water protection is long overdue. Currently, we are trapped in a cycle of escalating costs, forced to treat symptoms like algae and invasive weeds expediently with chemicals while the underlying risk in the reservoir compounds. True risk management requires breaking this cycle.
  6. How To Choose Among Wastewater Screen Options 4/8/2026

    Wastewater screening isn’t one-size-fits-all. The right choice depends on flow, debris, and efficiency needs, with long-term performance and maintenance costs shaping the best solution.

  7. Lowering Project Costs With AquaNereda® Aerobic Granular Sludge Technology 4/8/2026

    Aerobic granular sludge enables compact, energy-efficient nutrient removal, helping utilities increase capacity and reduce costs without expanding footprint or relying on complex, multi-stage treatment systems.

  8. The AWWA Said $2.4 Trillion. It Missed The Compound Interest. 4/1/2026
    Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
  9. Case Study: Groundwater DWTP (AK) - DEXSORB Full-Scale 3/29/2026

    A DWTP client in Alaska detected elevated PFAS contamination levels in two groundwater wells supplying drinking water to 85 service connections. PFAS concentrations are provided in Table 1, where combined concentration of EPA PFAS6 was detected at 490 to 810 ppt.

  10. Return Activated Sludge Pumps 3/27/2026

    Return activated sludge pumps are critical to wastewater treatment, maintaining biological balance, ensuring efficiency, and supporting resilient infrastructure amid aging systems and emerging contaminants.
