Hyperbaric disc filter dewatering of coal flotation concentrates is common place in China, Eastern Europe and Russia. The hyperbaric disc filter uses an air pressure of up to 0.6 MPa, to drive the dewatering process. This additional pressure is able to achieve surface moisture levels significantly less than conventional vacuum filtration.
