Greensand Filters | Greensand Filtration - Process Water

For iron alone, chlorine fed at a concentration of 1.0 to 1.2 times the iron should be adequate to oxidize the iron and "regenerate" the manganese greensand. Since excess chlorine is not deleterious to greensand filtration, it is possible to feed enough to provide adequate free chlorine residual in the filtered water sufficient for introducing into the clearwell and pumping to service.
