The filter only uses hydraulic loading to create the required media porosity without any mechanical compressing devices. A proprietary backwash sequence enables maximum recovery, extends media life, and limits energy consumption. This process significantly reduces the footprint compared to sand filters, and reduces maintenance and replacement costs required by disc filters, and other compressible media filters.

Filtration:Raw water enters the filter through the top and then flows downward. The hydraulic load compresses the media and creates an ideal medium porosity to retain solids. Captured by the media and filtrate solids then exit through the nozzles at the bottom of the filter.

Backwash:Phase 1: compressed air is injected at 15 scfm/ ft2 plus water at 10 gpm/ft2 for 3 minutes to uncompress the filter media bed.
Phase 2: media is washed using compressed air at 10 scfm/ft2 and water at 10 gpm/ft2 for 20 minutes.
Phase 3: air is removed from the media by pumping water at 10 gpm/ft2 for 5 minutes.
Phase 4: air is purged from the filter plenum for 2 minutes.
