WWTP Tour - Sludge Handling

Waste sludge from the clarifiers is pumped to an equalization tank where- variations in flow and concentration are equalized prior to processing. From the equalization tank the sludge is pumped to belt presses where most of the remaining liquid is removed. This liquid is recycled back to the Headworks to be treated The "cake" that comes off the belt presses is transferred by conveyor and high pressure pumps to the Stabilization Building, where it is treated with Lime (Calcium Carbonate) and dropped into trucks for transport off the plant. At this point the material is almost identical to the manure you purchase at your local garden supply store. Well that's the end... So let's go back.
