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
