Jun 18, 2020 How belt filter presses work. A belt filter press BFP provides sludge dewatering by pressing the sludge to force the water through a permeable medium. The process produces a cake the dewatered product having a dry solids DS content of 30 or more in the case of primary sludge. This is to be distinguished from the lower-energy gravity belt ...
When there is enough wastewater in the sludge thickener, the slurry from the tank is pumped into the Filter Press. The filter press separates the liquids and solids using pressure filtration. Sludge Cake will form between the filter plates, where it can be safely removed and easily discarded. The filtered water is then sent to the pump station.
