Schreiber Fuzzy Filter: Brochure

The Schreiber Fuzzy Filter is an innovative and cost effective compressible media filter for water and wastewater treatment systems. The Fuzzy Filter system is compact, modular, and easily adaptable for numerous applications. The Fuzzy Filter, operating in an upflow design, achieves an exceptionally high rate of solids removal through the use of compressible synthetic fiber spheres. The low density and high porosity of the media result in more solids captured per volume of media. Because the filter media is compressible, the porosity of the filter bed can be altered to suit influent characteristics. The filter media also represents a departure from conventional filter media in that the fluids to be filtered flow through the media as opposed to flowing around the media as in sand and anthracite filters. These innovative features permit dramatically higher hydraulic loadings of 40 GPM/ft2 and greater. Other filtration systems are typically limited to loadings of only 2 to 6 GPM/ft2.

The Fuzzy Filter utilizes air scouring during the wash cycle to clean the media. Influent continues to enter the filter (filtered water is not necessary for washing) while an external blower supplies air to the diffusers located in the bottom of the filter to violently agitate the media. The media, which is retained between two perforated plates, is subjected to vigorous air scouring to free captured solids. Liberated solids continuously exit the filter with the wash water passing through the vessel. After the washing cycle, the media is returned to its compressed state and filtration is resumed.
