Manganese GreensandPlus
(for Iron Removal)

 

The silica sand core of GreensandPlus allows it to better withstand operating conditions in waters that are low in silica, TDS and hardness. Thus, if you currently are using manganese greensand and are feeding sodium aluminate, you will likely be able to eliminate the aluminate feed by switching to GreensandPlus. 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. 44lbs. per bag.

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.

Manganese GreensandPlus

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 Greensand has a glauconite core and the coating is ionically bound to it.

The silica sand core of GreensandPlus allows it to better withstand operating conditions in waters that are low in silica, TDS and hardness. Thus, if you currently are using manganese
greensand and are feeding sodium aluminate, you will likely be able to eliminate the aluminate feed by switching to GreensandPlus. 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. It can be used in CR and IR applications and requires no changes in backwash rate or times or chemical feeds. GreensandPlus has received the WQA Gold Seal Certification for compliance with NSF/ANSI 61. It is available in easy-to-handle 1/2 cubic foot bags.
