Ovivo® QuadraKleen™ Filter

The Ovivo® QuadraKleen™ filter is a modular, four-cell granular media filter that delivers economical, continuous filtration in a variety of water treatment flow sheets. Each module consists of four filter cells clustered around common influent, effluent and backwash channels. This allows individual cells to be backwashed using water produced by one of the other three cells, eliminating the need for backwash water storage and minimizing filtration rate during backwash.
  • Flexible design adapts to a wide range of filtration requirements.
  • Accommodates virtually any flow volume.
  • Automated unit controlled from a central location.

QuadraKleen™ filters easily adapt to a wide range of filtration requirements. Its flexible basin geometry easily accommodates a variety of mono or dual media bed depths and media types, including sand, anthracite and granular activated carbon. Multiple QuadraKleen filters can be arranged around common influent/effluent channels, accommodating virtually any flow volume.

  • Air scour cleaning reduces duration of backwash cycles and wash water volumes.
  • No need for backwash water storage, reducing costs.
  • Central access column simplifies maintenance.
  • Constructed from durable materials and fully factory assembled.

The QuadraKleen™ filter cell is entirely constructed from concrete. The steel central valve access/waste drain column is prefabricated and fully factory assembled. The CastKleen® filter under drain features monolithic slab construction and FlexKleen® Mark 3 flow control nozzles. The FlexKleen nozzles require no gravel distribution layer, and their adjustable, flow-balancing tailpipes ensure uniform air distribution during air scouring of the filter media. Optional ScourGuard™ wash water collection troughs protect against media loss during air-assisted backwash.
