Sewage sludge treatment describes the processes used to manage and dispose of sewage Sludge treatment technologies that are used for thickening or dewatering of which sludge is fermented in tanks at a temperature of 55 °C, or mesophilic, . Co-firing in municipal waste-to-energy plants is occasionally done, this
Thickening and dewatering - Reduce the amount of waste for disposal by up to 90% Mechanical thickening of sludge from primary or secondary clarifiers has replaced gravity tanks as the industry norm prior to digestion or dewatering.
Primary sludge with the waste activated sludge is pumped to three heated primary using 2 Meter and 3 Meter Gravity Thickener Belts to reduce the sludge volume. in 2 2MG Aquastores until it can be dewatereddried or applied on farmland The two sludge holding tanks provide 180 days of storage capacity so the
Sludge can be dewatered directly from a concentration tank or sludge storage tank. Usually, sludge is thickened by gravitation in a sludge concentration tank or
Secondary sludge e.g. waste activated sludge is preferably thickened mechanically, separate from primary sludge. Polymers are added to the thin sludge for
