Application Report #26 (Screw Press & Bioset Process)
When the City of Prattville, Alabama, recently chose to upgrade its Pine Creek wastewater treatment facility, it spared no effort in doing so. While they had made smaller, incremental modifications in the past, this time around they took the plant from simply adequate to boldly forward-thinking, designing it to be viable and effective for at least the next quarter century. Included in the wholesale changes was a rethinking of its solids handling capability which, up to that point, was both basic and costly.
Today, the Pine Creek Clean Water Facility uses a new approach to aeration, dewaters through a pair of new screw presses, is generating a Class A biosolids for area land application, and is now accepting sludge from a nearby sister facility. In this case, being up a creek is definitely a good thing.
