System provides town with flexibility for future capacity needs 

Problem: Geraldine, Alabama, with a population of about 1,100 people, needed a wastewater treatment system that was easy to operate and could be expanded to accommodate future growth. The system would treat domestic waste to regulatory limits to allow for drip dispersal and handle flow fluctuations, and ensure the drip headworks wouldn’t clog and the dispersal field wouldn’t experience excess biomat development.

Solution: An ECOPOD advanced wastewater treatment system with a drip dispersal field from Delta Treatment Systems was selected for the 60,000 gpd system. The units treat incoming wastewater with an expected strength of approximately 300 mg/L incoming BOD/TSS loading, down to 30/30 effluent limit requirements. Each home is equipped with a septic tank effluent pump system that moves influent to the treatment system. The system has a flow equalization tank with duplex alternating pumps, four E1600 units installed in parallel, then a dosing chamber with duplex alternating pumps that provide controlled dosing to the dispersal field. Oxygen pumped into the system allows bacteria to thrive in much greater numbers than would occur naturally, speeding the breakdown of the sewage and making it safe for release into the environment. The intra-tank bioreactor treatment system is buried in a cast-in-place concrete tank.

Result: As the town continues to expand, the system is designed to grow with it and addition of extra trains will be easy and cost-effective. 800-219-9183;
