FUNDABAC® Candle Filter Process

The FUNDABAC® Candle Filter housing is a vertical, cylindrical pressure vessel, equipped with a bolted-on lid at the top for mounting the filter elements, and a conical bottom portion for the discharge of solids. Because of this simple construction and no moving parts, it is possible to apply various kinds of materials of construction for the vessels and to take advantage of process-oriented claddings or linings. During filtration, the liquid passes from the outside through the filter media into the six concentric perforated tubes and flows down into the bottom of the candle where the filtrate is deflected into the center tube, flowing up into the horizontal register and out through the filtrate outlet. For discharging the cake, the pressurized gas flow is reversed and blows up the filter media around the tubular element. This sudden dynamic expansion of the media makes the cake break, drop into the cone of the filter vessel and out through the discharge valve. Find out more about our FUNDABAC® F
