This filter contains manganese greensand which reduces these contaminants through an oxidation / filtration process, thereby substantially improving water clarity, taste, and odor, while at the same time protecting your plumbing system including toilets, bath tubs and showers, and appliances such as clothes washers and dishwashers from unsightly staining.
It adds no harmful chemicals to the water, making it completely safe for drinking water applications. Iron and manganese reduction will also prolong the life of a reverse osmosis membrane or BelKraft water purifier in your home. This filter should be installed on the main cold water line after the pressure tank or water meter. For best results, pre-sediment treatment is recommended. We use a 50 to 5 micron DUAL-GRADIENT DENSITY, PRE-FILTER CARTRIDGE.
Application: This system should be employed as a whole house application where low to moderate ferrous (dissolved) iron, manganese, or hydrogen sulfide contamination is known or expected. This filter will also remove ferric iron through mechanical filtration, although a sediment filter may be a more cost effective choice. This filter is most effective where iron contamination level is less than 3 ppm (and no greater than 5 ppm) or the hydrogen sulfide level is less than about 2 ppm. While the filter will indeed remove these contaminants when these levels are exceeded, the filter life expectancy may be shortened significantly, and contaminant removal may be incomplete. If a combination of iron, manganese, and hydrogen sulfide are present, you must consider the "iron equivallent" level when determining if this filter will work effectively in your circumstance (see below). Best contaminant removal rates are achieved where the pH is 7.0 or higher for iron and hydrogen sulfide reduction.
This filter is not recommended where pH levels are less than 6.9. For pH levels ranging from 6.5 to 6.9, we strongly recommend the Delux iron filter .
The life of the filter depends on the contamination level ("iron equivalent") and amount of water consumed on a daily basis. You can get a good idea of how long a filter will last in your case by using the chart below.
"Iron Equivalent" is calculated as follows: (Iron level) + (2 x Manganese level) + (3 x Hydrogen sulfide level)
If your level of Hydrogen sulfide is unknown (it is hard to accurately test for) and you have a noticeable "rotten egg" odor, assume a Hydrogen sulfide level of 0.5 ppm. If the rotten egg odor is severe, assume a level of 1.0 ppm.
Example: Test results are 0.8 ppm iron, 0.2 ppm manganese, and you have a rotten egg smell in your water.
Iron Equivalent = (0.8) + ( 2 x 0.2) + (3 x 0.5) = 2.7
Approximate Life of Filter Cartridge
What types of contaminants are you dealing with?
How it Works: Soluble iron (ferrous) and manganese are oxidized and precipitated by contact with higher oxides of manganese on the greensand granules. The hydrogen sulfide is reduced by oxidation to an insoluble sulfur precipitate. The precipitates are then filtered. Ferric iron is removed by mechnical filtration.
