Sludge & Biosolids Processing Resources

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. California's First Installation Of 2nd Generation ATAD 6/11/2025

   Calera Creek Water Recycling Plant, located in Pacifica, California, recently retrofitted to the Thermal Process Systems’ ThermAer™. This is California’s first installation of the second generation ATAD system.

7. The Real Cost Of Wastewater Treatment: MBR Reshapes The Equation 6/2/2025

   For years, conventional activated sludge (CAS) has been the default in wastewater treatment. But the industry is changing.

8. Sludge Costs Are Wrecking Wastewater Budgets. Here's How MBR Can Help 4/25/2025

   Sludge management costs aren’t going away, so your team needs to find a solution. Land application bans, PFAS regulations, and rising disposal costs are making sludge an even bigger financial liability.

9. How A City's Sewage System Can Generate Renewable Natural Gas Production And Earn Royalties 12/16/2024
   Imagine if wastewater treatment plants (WWTPs) — typically associated with managing sewage — could instead become known for fueling a more sustainable future.
10. Time-Based Treatment Is A Game Changer For Activated Sludge, Granular Sludge, And Densified Sludge 10/15/2024

    Time-based batch processing allows WWTPs to gain the benefits of new suspended growth technologies in a much smaller footprint.
