Achieve clear filtrate with these candle filters

The further developed CF Series candle filters are particularly suitable for purifying industrial wastewater with low solids content. They have been specially developed for the filtration of liquids with solid concentration of less than 1% — an area of limited cake-building capabilities in which other filters fail. Even in the case of very fine particles with low solids content, they produce a clear filtrate. With filter areas ranging from 1 to 150 m², they are designed for throughput rates of up to several hundred cubic meters per hour. One special feature of the candle filter is that filtered solids do not form a sludge, but a pre-dried, semi-solid filter cake with a solids content of between 50 and 80%, thus significantly reducing the disposal volume compared with filter types with solids contents of 10 to 20%, says the company. — BHS-Sonthofen GmbH, Sonthofen, Germany
