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. 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.

3. 2nd Generation ATAD Provides High Quality Biosolids With Increased Capacity 3/16/2026

   Modernize solids handling with automated aerobic digestion to manage rapid community growth. This high-rate process increases capacity, ensures Class A compliance, and significantly reduces disposal costs while providing odor-free operations through advanced nutrient and off-gas management.

4. 2nd Generation ATAD System Improves Capacity While Producing Odor-Free Biosolids 3/16/2026

   Upgrade wastewater operations with automated aerobic digestion. This advanced process increases capacity and ensures stable temperature control for Class A compliance, producing odor-free biosolids and efficient nitrogen removal to meet strict environmental standards and community expectations.

5. How Sewage Treatment Plants Could Handle Food Waste, Sparing Landfills And The Climate 3/13/2026

   Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.

6. MBRs As A Compliance Safety Net: Keeping BOD/TSS Below Detection Even Under Stress 12/11/2025

   Maintain strict permit compliance even when hydraulic shocks or seasonal loads hit your system. Membrane filtration ensures dependable removal of solids and organic load, providing a critical process stability buffer against unexpected compliance risks.

7. Aqua TruDense™ Provides Additional Capacity, Improves Settling, And Achieves Enhanced Nutrient Removal 9/4/2025

   A densified sludge process can improve wastewater treatment by promoting larger, denser sludge particles. This enhances settling, improves nutrient removal, and increases treatment capacity.

8. ATAD Provides Increased Capacity With No Odors 7/1/2025

   Faced with persistent odor complaints and limited space, Douglas County Sewer District #1 in East Wenatchee, Washington, turned to the ThermAer second-generation Autothermal Thermophilic Aerobic Digestion (ATAD) system to modernize its biosolids treatment.

9. Anaerobic Digestion Optimization System Provides Exceptional Improvements 6/18/2025

   Faced with soaring ammonia loads—especially during race weekends when 250,000+ fans descend on the town—the Speedway, Indiana Wastewater Treatment Plant was in urgent need of a solution.

10. 2nd Generation ATAD Provides Superior Treatment 6/18/2025

    In a bold move to modernize its wastewater treatment, Bowling Green, Ohio, installed the state’s first second-generation Autothermal Thermophilic Aerobic Digestion (ATAD) system—ThermAer—in 2004. The upgrade expanded the plant’s capacity from 6 to 10 MGD and replaced an inefficient, odor-prone coarse-bubble aeration system.
