Reinforced polypropylene filter press type ¢ò evolved by ordinary filter, the main difference with ordinary filter press is an increase in the compression cylinder bore and the corresponding increase in the strength of filter rack , Which can tolerate higher filtration pressure. If the ceramic piston pump and with the use, in comparison with ordinary filter, can reduce the moisture content of filter cake of 10-15 percentage points, can be used in kaolin, ceramics, and environmental protection industries, in environmental protection especially for the industry on the need for sludge drying, incineration, due to low moisture content, can greatly reduce the drying of sludge incineration process energy consumption.
