Low-Cost Grit Removal Method

Ideal for smaller treatment facilities, the In-Line Grit Collector is an aerated grit chamber. It is an all in one unit consisting of a settling chamber with an air diffuser, grit screw, and an effluent trough. Air maintains circulation in the grit chamber for all flow conditions keeping lighter organic material from settling. The heavier grit particles, which settle to the chamber floor, are removed by an inclined grit screw for disposal.


  • Ideal grit removal for treatment plants with a peak flow less than 6.0 mgd
  • Diffuser circulates the liquid to minimize the settling of organic material
  • All motorized parts are above water for easy maintenance
  • Optional stainless steel construction for corrosion resistance
