Model PP -Grit Washers
The grit washer is designed for intensive grit washing and the removal of organic matters in grit. Grit washer is placed at a further stage after the grit separator. By intensive grit washing mostly all residual portion of organic substances are removed. The hydro-mixture in the grit chamber is first pumped into the grit separator. Here the initial rough separation of grit from the remaining solid phase is carried out. By subsequent washing the grit is rid of almost all the residual portion of organic substances.
