WASTEWATER TREATMENT LINES FOR IMPROVED CARBON UPTAKE THROUGH CAKE FILTRATION OF WASTEWATER

摘要

The field of the invention is wastewater treatment, including both municipal and industrial wastewaters. Wastewater treatment plants have long been seen only as environment protection plants. The invention tends to turn WWTP (wastewater treatment plants) into water resource and recovery facilities, turning wastewater treatment plants into energy and resource producing plants. WWTP may no longer be facilities designed and operated to remove water pollution like carbon, nitrogen or phosphorus, but may be turned into plants valorizing the constituents inside raw wastewater. The invention is directed to filtering wastewater using cake filtration, the cake filter having been created by depositing a mixture of primary and/or biological sludge and digested sludge from the digestion of primary sludge and/or biological sludge on a fluid penetrable support surface.
