Problem: Operators of the Indiana Southport Advanced Wastewater Treatment Plant in Indianapolis sought to eliminate the need to periodically take JS 101 B out of service for cleaning due to grit accumulation.
Solution: A pulsed air system from Pulsed Hydraulics was selected due to its higher mixing energy and better ability to keep or re-suspend solids throughout the entire tank. The system can be operated on a continuous basis or may be operated intermittently, based on operator preference. The system includes 24 bubble forming plates located in the channels and basin. Pulsed Hydraulics supplied three 4-valve mixing panels with Allen-Bradley PLC and two rotary screw 20 hp compressors.
Result: Requirements were met and verified by the customer’s engineer. 800-641-1726; www.phiwater.com
