Reduce Lifecycle Costs For BNR With A Phased Activated Sludge System

Many wastewater utilities are under regulatory mandates to reduce effluent nitrogen and phosphorus. When trying to determine the best method for biological nutrient removal (BNR), lifecycle costs are an important factor.

Aqua-Aerobic Systems, Inc., has been a leader in the design, application and manufacture of wastewater treatment equipment and systems since 1969. Water Online spoke with Manuel de los Santos of Aqua-Aerobic Systems about how Phased Activated Sludge Systems (PASS) can provide enhanced BNR while keeping lifecycle costs down.
