Greensand-Plus Filter Media uses catalytic oxidation to remove iron from well water, with or without manganese. Chlorine or another strong oxidant is added to the raw water before the filter, allowing enough time for effective treatment. A small amount of chlorine passing through the filter keeps the media continuously regenerated for optimal performance.

For operation using chlorine, the demand can be estimated as follows: 
mg/L Cl2 = (1 x mg/L Fe) + (3 x mg/L Mn) + (6x mg/L H2S) + (8 x mg/L NH3)

Features

• The manganese dioxide coated surface acts as a catalyst in the oxidation reduction reaction of iron and manganese
• The silica sand core allows it to withstand waters that are low in silica, TDS and hardness without breakdown
• Effective at higher operating temperatures and higher differential pressures than standard manganese greensand. Tolerance to higher differential pressure can provide for longer run times between backwashes and a greater margin of safety
• Systems may be designed using either vertical or horizontal pressure filters, as well as gravity filters
• Proven technology for iron, manganese, hydrogen sulfide, arsenic and radium removal. Unlike other media, there is no need for extensive preconditioning of filter media or lengthy startup periods during which required water quality may not be met
• Exact replacement for manganese greensand. It can be used in CO or IR applications and requires no changes in backwash rate or times or chemical feeds
• WQA Gold Seal Certification for compliance with NSF/ANSI 61.
