Includes:

• Media: Greensand Plus Manganese Greensand
• 0.5 cubic foot bag inside a box, 44 lbs

Specifications:

• GreensandPlus is a purple-gray filter media used for remov-ing soluble iron, manganese, hydrogen sulfide, arsenic andradium from well water supplies.
• Like its sister product manganese greensand, the substratemedia has a manganese dioxide coated surface that acts as acatalyst in the oxidation- reduction reaction of iron and man-ganese.
• The difference between GreensandPlus and man-ganese greensand is in the substrate that forms the core ofthe media and the method by which the manganese dioxidecoating 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 sili-ca, TDS and hardness.
• Thus, if you currently are using man-ganese greensand and are feeding sodium aluminate, you will likely be able to eliminate the aluminate feed by switching to GreensandPlus.
• Also, Greensand Plus can withstand higher operating temperatures and higher differential pres-sures 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 Greensand Plus is an exact replacement for manganesegreensand.
• It can be used in CR and IR applications and requires no changes in backwash rate or times or chemical feeds.
• Greensand Plus 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.
• Greensand Plus is NOT shipped in a regenerated form; there-fore it is necessary, prior to use, to regenerate it contacting the bed for a minimum of 4 hours.
