Sludge percent solids calculation
WebbIt depends on the type of wastewater. In the raw sewage water, you can assume the VSS around (30 - 40%) of total SS. However, the water treated after primary classifier has 65 - 80% VSS. Finally,... Webbbe reduced by stabilisation. A high water content (fi low percentage of total solids) makes the handling difficult, causes high cost for transportation and storage and should therefore be reduced. 2.
