Hydrostatic Clarifier


The Hydrostatic clarifier continuously removes solid particles from water-based emulsions and oils. The filter chamber is built as a wedge shape with the filter area running up the sloping edge, this makes the filter compact and space saving. The Hydrostatic Clarifier is a versatile filter that handles flow rates between 100 – 2000lpm and filters down to 10 μ when a fine filter media is used.

The liquid enters the top of the filter to reach the filter fabric, which lies up the sloping filter area. The liquid flows through the filter fabric, which retains the solid particles when the filter fabric becomes blocked with contamination. When the fabric becomes blocked a level sensor activates the re-wind drive which draws in a fresh length of media. A sludge scraper removes the bulk of the sludge from the fabric. When Permanent filter media is used (ELM), the media is continuously recirculated and the media is clean through flushing or/and air nozzles.

  • The filter has a very high capacity and filtration efficiency to the price 
  • Minimum maintenance due to very few moving parts 
  • Minimum floor area for higher flow rates 
  • Automatic re-winding of contaminated media giving easy disposal
