Abstract
An alluvial filter candle apparatus has a plurality of filtering elements each of which has a return casing surrounding a riser lower end provided with a filtrate inlet opening and preventing backflow of the filtrate through the filter cake. The volume of the return casing corresponds to that of the riser. The risers are formed as mounting rods which mount candle-like filtering bodies of the filtering elements to a partition subdividing a filter housing into a filtrate chamber and a filtrant chamber. The partition sealingly abuts against and is movable relative to the filter casing. An arrangement is provided for forcedly displacing the partition together with the filtering element so as to separate the filter cake from the latter. A method of cleaning the filtering apparatus is also provided.
