Manganese treated greensand plus must be supplied with sodium hypochlorite or potassium permanganate on a continuous basis. Normally a chemical feed pump is used for this purpose. Chemical is pumped into the raw water prior to contact with the greensand filter.  Contact our commercial support department for help with sizing and pricing of the chemical pumps.
