Filter presses. These consist of a horizontal series of filtering chambers formed by readily detachable vertical filter plates and frames; these are covered by a filtering medium (cloth, cellulose, etc.), and are held in place by a screw or press mechanism. The liquid is forced through the cells by a pump, and the chambers may be heated internally by steam, etc. The filtrate is drawn from the press and the residue collects in cakes between the plates. Filter presses are used for filtering or clarifying many liquids (e.g., in the chemical industry, the sugar industry, in brewing, wine making, oil purification, ore concentration, in the manufacture of ceramics, man-made textiles, etc.).
