Manganese Greensand is a purple black filter media used for removal of soluble iron, manganese and hydrogen sulfide from well water supply. The manganese dioxide act as a catalyst in the oxidation - reduction reaction of iron and manganese. The media can be used in two methods of operation : Continuous Regeneration and Intermittent Regeneration. The unique microporous structure of greensand efficiently removes dissolved iron to as low as 0.005ppm and manganese to 0.001ppm after initial activation.
