Greensand Plus

categorie-afbeelding

Greensand Plus is a purple-charcoal filter media used for removing soluble iron, manganese, hydrogen sulfide, arsenic and radium from well water supplies. It can operate at high flow rates with moderate backwash requirements.

Like its sister product manganese greensand, the substrate media has a manganese dioxide coated surface that acts as a catalyst in the oxidation- reduction reaction of iron and manganese. The difference between Greensand Plus and manganese greensand is in the substrate that forms the core of the media and the method by which the manganese dioxide coating is attached to that substrate. Greensand Plus has a silica sand core and the coating is fused to it while Manganese Greensand has a glauconite core and the coating is ionically bound to it. This coating is maintained through regeneration with potassium permanganate.
