Dewatering of Sewage Sludge with Vacuum Assisted Sludge Dewatering Beds

Water Science and Technology, 1992
The “Rapid Sludge Dewatering System (RSDS)”, in which the sludge is dewatered by way of vacuum supported sludge drying beds, was tested for performance, efficiency and applicability. Generally, the RSD-System can be regarded as an alternative to other sludge dewatering systems, especially for small purification plants, for agricultural use and ...
