Candle kieselguhr filter

The filtering layer consists of a filtering material (most often diatomaceous earth), washed on a filtering support - a stainless steel candle of a special design, which ensures strength, durability and high efficiency of the equipment. Filter medium - suspension (most often diatomaceous earth) is prepared in a mixing tank. The base layer is applied to the candle using a fast coating method - with the help of a circulation pump, kieselguhr, which is in the liquid stream, sticks to the surface of the candle and thus forms a filter layer.

The liquid to be filtered with the help of a circulation pump flows through the filter layer, on which mechanical particles of turbidity are trapped. In order for the filtration cycle to be efficient (retaining a large amount of impurities) and economical, it is necessary to add a certain amount of kieselguhr to the candle during the process with a dosing pump. In this way, the sludge remains in a permeable state, which maintains long-term filtration efficiency. After filtration is completed, it is removed from the candles either manually or by semi-automatic hydraulic flushing. Kieselguhr filtration provides low operating costs per filtered liquid volume, high productivity and efficiency.
