Greensand is a filter media used for removing soluble iron, manganese, hydrogen sulfide, arsenic and radium from well water supplies. 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 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 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. The silica sand core of Greensand allows it to better withstand operating conditions in waters that are low in silica, TDS and hardness. Also, Greensand can withstand higher operating temperatures and higher differential pressures than can manganese greensand. The higher differential pressure may allow for a longer run length, but, if nothing else, allows for more operational margin of error.
