Web6 Mar 2024 · Sludge thickening is an important process in treating solid waste. It minimizes the water waste, enabling the re-treatment of … WebBy comparing HDM simulations with the lab-scale anaerobic digester operation at 55 °C, the first-order kinetic constants for the serial hydrolysis reactions were estimated. The VSS fractionation provided a clear understanding of hydrolysis reactions and detailed mass flow with time in thermophilic AD of thickened waste activated sludge.
What is the Sludge Thickening Process in Water Treatment?
WebSLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8% solids, can be thickened to a content of 4% solids, then a fivefold decrease in sludge volume is ...
