Gravity Media Filters

Wigen designs and builds custom gravity media filters for a wide variety of industrial and municipal applications. As the name implies, gravity is used as the motive for a fluid stream to pass through a bed of granular media through which physical and/or chemical removal of impurities is achieved. Gravity filters are ideal for treating larger volumes than pressure filters can economically handle. Our systems are manufactured in-house, to ensure quality control, while keeping the capital cost down.

Impurities Commonly Removed by Gravity Filters

  • Iron & Manganese
  • Suspended Solids
  • Taste & Odor
  • Color
  • Organics (TOC's & SOC's)

Gravity Filter Configurations

  • Vertical Cylinder Gravity Filters (< 500 gpm per unit)
  • Horizontal Rectangular Gravity Filters (>500 gpm per unit)

Gravity Filter System Types

  • Activated Carbon - for removal of chlorine and organics
  • Manganese Greensand - for removal of iron and manganese
  • Dual-Media - for removal of heavy sediment & suspended solids
  • Sand - for removal of heavy particulate & sediment
