1. Eradicating High-Strength Nitrogen Loads Without Expanding Your Aeration Basins 5/1/2026
   When decision-makers assess the best ways to deal with high-strength nitrogen loads in their wastewater treatment plants, an important thing for them to remember is that biological treatment methods alone typically cannot handle all of a facility’s nutrient load. Instead, they should consider how a combination of physical-chemical extraction methods can provide an extremely reliable, small footprint method for handling above-average loads.
2. Optimising Coagulation And Flocculation Systems In Surface Water Facilities 3/23/2026

   Coagulation and flocculation remain essential but increasingly sensitive processes, requiring flexible design and real-time optimisation to maintain performance across widening source water variability.

3. Sustainable Wastewater Solutions For Today's Challenges 3/13/2026

   Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.

4. Rethinking Aeration: Demand-Based DO Control And Energy Optimization 3/13/2026

   Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.

5. National Wastewater Surveillance System Funding Appears Secure For 2026 2/23/2026

   The U.S. National Wastewater Surveillance System (NWSS), run by the Centers for Disease Control and Prevention (CDC) since 2020, appears to have averted a funding crisis when U.S. President Donald J. Trump signed H.R. 7148, the Consolidated Appropriations Act, 2026, into law on Feb. 3, 2026.

6. Liquid-Only Sewers: A New Approach To Decentralized Wastewater Collection 1/14/2026
   Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.
7. Pretreatment Filtration For Small Systems: The Expensive Pitfalls Of Low-Cost Equipment 10/30/2025

   When seeking bids for a fair comparison, it’s important to evaluate the total cost of ownership.

8. Designer Microbes: Can Synthetic Biology Supercharge Wastewater Treatment? 7/3/2025

   Exploring the potential of bioengineering as a pathway to pollution remediation.

9. CERCLA And PFAS: What's The Liability For Water And Wastewater Utilities? 5/2/2025
   Federal rules aim to target those liable but may miss the mark. Utilities can redirect the effort — and costs — to those truly responsible for PFAS contamination.
10. 8 Trends In Decentralized Wastewater Treatment: Shaping A Sustainable Future 1/7/2025
    Centralized wastewater treatment is sometimes not an option — and sometimes simply not the best choice, considering the expanding capabilities of decentralized systems.
