GreensandPlus is a purple-gray 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 GreensandPlus 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. GreensandPlus has a silica sand core and the coating is fused to it while Manganese
Also, GreensandPlus 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.
Along with the added benefits comes the fact that GreensandPlus is an exact replacement for manganese greensand. GreensandPlus has received the WQA Gold Seal Certification for compliance with NSF/ANSI 61.
GreensandPlus is NOT shipped in a regenerated form; therefore it is necessary, prior to use, to regenerate it contacting the bed for a minimum of 4 hours.
