The innovative and cost effective Fuzzy Filter™ uses a compressible media filtration system which allows operators to adjust media porosity to suit their influent characteristics at the push of a button. This compact, modular filter can be used in a wide variety of water and wastewater applications to attain flow rates up to 45gpm/ft2, reduce wash water usage and maintenance, and enjoy dramatic space savings over traditional granular media filters.

The Fuzzy Filter uses a nominal 30” deep media bed comprised of individual 1.25” 1.5”-diameter compressible synthetic fiber spheres, and achieves a high rate of solids removal down to 4 microns. By mechanically compressing the media, operators can alter the total porosity of the filter bed to suit influent characteristics. The media porosity and solids removal can be optimized to maximize solids capture and run time. The filter uses both influent water and air scouring during wash to dislodge captured particles without media loss, cleaning easily with very little wash water.

The Fuzzy Filter is available in sizes from 2.25 to 64 ft2 with flows ranging from 0.13 MGD to 3.68 MGD at a loading rate of 40 GPM/ft2.
