Pooler Wastewater Treatment Plant & Upgrade
The first phase of this project consisted of a new 2.5 MGD hollow fiber (GE ZeeWeed) membrane bioreactor (MBR) plant constructed on a very small tract of land next to an existing 0.98 MGD aerated lagoon facility. In the second phase, Hussey Gay Bell completed a hydraulic capacity upgrade from 2.5 MGD to 3.3 MGD in 2015, along with several capital improvement projects designed to replace aging equipment and improve reliability. As the plant has gotten closer to its hydraulic capacity of 3.3 MGD, Hussey Gay Bell designed an expansion to 6.223 MGD of which entails a new headworks with an additional bar screen and grit headcell unit, conversion of the existing aeration basin to an additional equalization basin, new fine screens, a new membrane bioreactor, new UV disinfection system, additional effluent pumps, additional post aeration, and a new sludge digester. The new headworks facility will give the ability to discharge screened wet weather flows to the existing holding pond. The new MBR has been designed to improve the biological treatment process to remove phosphorous.
