Depth Filters With Air Scour

Depth Filter with Air Scour : Application and Benefits

Depth filters are used in water treatment.

Depth filters with air scour are used to reduce turbidity in medium turbidity waters.

Typical application is turbidity removal, using a coagulant or filter aid, for direct filtration water treatment plants.

  • Fully automatic, backwashing on delta pressure and time inputs.
  • Multi-media configuration to allow long filter runs and low micron filtration.
  • Air scour used in the backwash process to ensure full removal of floc particles from the filter media.
