Greensand-kt, Color : Black

Greensand KT is effective at higher operating temperatures and higher differential pressures than ordinary manganese greensand. Greensand KT is a black filter media used for removing soluble iron, manganese, hydrogen sulfide, arsenic, and radium from water supplies. The manganese dioxide coated surface of Greensand KT acts as a catalyst in the oxidation reduction reaction of iron and manganese.

Systems may be designed using either vertical or horizontal pressure filters, as well as open gravity filters.

Greensand KT is a proven technology for iron, manganese, arsenic, radium, and hydrogen sulfide removal. Unlike in-situ treated media, there is no need for extensive preconditioning of filter media or lengthy startup periods, during which required water quality may not be met.
