Filter presses are used to dewater sludge from the underflow of thickener tanks. Filter presses operate on a batch process and produce a dry silt cake that is typically between 20% and 30% moisture.
The basic principle involves thickened sludge being pumped in under pressure to the chambers within the press. Each filter plate is covered by a filter cloth and as the sludge is pumped in the water drains through the filter cloth and exits the plates. When the water has sufficiently drained to the required moisture content the press automatically opens and discharges the dry cakes into a stocking bay below.Send Enquiry ›
