Candle Filter CF separation problems solved safely  


Brochure   -   Candle filter


 BHS Candle Filters are batch operated units with filter elements arranged vertically inside a pressure vessel. They are used as deep bed or precoat filters for clarifying liquids with low solids content. The filter works fully automatic under contained conditions.

The feed suspension is constantly pumped into the pressure vessel until the required cake thickness is reached. The filter cake is formed on the outside of each filter candle, the filtrate being discharged from the inside of the candles through immersed and register pipes. After filtration the filter cake can be washed and/or dried. Finally, the cake is lifted by a blast of compressed air and discharged without any residues.

BHS also provides complete candle filter installations including fittings, instrumentation, piping, pumps, tanks, skid and PLC control systems. The plants have a modular design for easy transport and fast on-site assembly.
