Pressure Media Filters

Wigen is a leading producer of custom-built pressure filter systems for a wide variety of industrial and municipal applications. Pressure filters utilize a process in which, a pressurized fluid stream contacts granular media for physical and/or chemical removal of impurities. We design our pressure filter systems to ensure the right media products are used to meet the client's desired effluent and waste stream requirements. Often we are able to incorporate our patented reclamation technologies to greatly reduce the amount of waste water produced from normal backwash operations.

Impurities Commonly Removed by Pressure Filters

  • Iron & Manganese
  • Arsenic
  • Radium
  • Chlorine
  • Organics (TOC's & SOC's)
  • Suspended Solids
  • Oils
  • Taste & Odor
  • Fluoride

Pressure Filter Configurations

  • Vertical Pressure Filters
  • Horizontal Pressure Filters

Common Pressure Filter System Types

  • Activated Carbon - for removal of chlorine and organics
