The WWETCO FlexFilter™ is a high rate filtration system utilizing synthetic compressible media. The compression of the media is accomplished through a lateral hydraulic force applied from the incoming liquid. This unique method of compression eliminates mechanically actuated internal components and provides for a tapered compression of the media.

The varied porosity of the compressed media bed allows for increased filtering capacity as well as the ability to treat flow streams with higher solids concentrations while minimizing backwash cycles. In addition to the filter's ability to handle higher solids to the filter, the backwash system with air scour and specialized backwash troughs minimize the volume of backwash water needed. The combination of media compression method and backwash system makes the WWETCO FlexFilter™ one of the most versatile and efficient filters on the market.
