Abstract
A suspension is filtered by preparing an auxiliary suspension of filter material, filtering the auxiliary suspension through vertical filter elements and evacuating filtrate until a layer of the material is held to the elements by hydraulic pressure and then filtering the first suspension through the elements while forcing filtrate to flow upwards. A filter for carrying out the process is also claimed. A vessel with a cover defines a chamber contg. vertical filter panels. The vessel has an inlet for suspension at its base, and filtrate outlets connected to collectors both above and below the filter panels. A liquid inlet is connected to a distributor tube with nozzles for clearing filter cake off the panels. The vessel also has an air inlet, a suspension outlet, a foot-valve and a manometer.
