Automatic Quartz Sand & Multi-Media Filters

Quartz Sand Filter Systems

20 Micron Depth Filtration for Suspended Solids and Turbidity Removal

Quartz sand and multi-media depth filters represent the essential first line of defense in water treatment. By stratifying graded quartz sand, anthracite and garnet gravel, they capture coarse particulates, sand, rust, silt and insoluble mineral flocs across the entire depth of the media bed.

Constructed in corrosion-resistant FRP composite vessels or epoxy-coated carbon steel tanks with pneumatic or motorized multi-port valves, our filters operate automatically based on differential pressure (DP) and timed cycles.

Advantages & Features

  • Multi-layer media bed (Graded Quartz Sand + Anthracite + Support Gravel)
  • Filtration precision down to 15 - 20 microns for raw suspended particulates
  • Heavy-duty FRP composite or epoxy/ebonite-lined carbon steel pressure vessels
  • Differential pressure (DP) and timer-triggered automated backwash cycle
  • Low head loss and prolonged media service life (5+ years without replacement)
  • Flanged butterfly valves with pneumatic actuators or smart multiport electronic valves
