At american water, we work with you to determine if your media is ready for replacement and provide you with the appropriate resin and media to keep your water systems in working order. greensand media for our customers utilizing an iron filter or greensand media, the resin is typically dependable for 58 years depending on the water source.
Chemical treatment and filtration. filter design greensand filters are typically designed to flow at 35 gpm per square foot of filter surface area and need a minimum of 12 gpm per square foot for backwash. backwash should be initiated manually or by pressure differential switch when the differential pressure across the filter increases by 12 psi.

Gradient ld greensand plus filters the manganese dioxide coated surface of the greensand plus media promotes the oxidation reaction of iron, manganese and hydrogen sulfide. effective at high temperatures and differential pressures, gradient ld greensand filters provide longer run times while reducing the number of backwashes.
Gravity filter overview gravity filters are commonly used in applications where liquidsolids separation is required in a variety of different applications for finish water treatment. gravity filters can incorporate various types of media such as sand, anthracite, greensand and gac to meet each plants water treatment needs.
Gravity filters. greensandplus is a 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. greensandplus is an exact replacement for manganese greensand.
Greensand filters unitech greensand filters are generally limited to application where the combined iron and manganese concentration is below 15 ppm. these filters feature dual media greensand anthracite loadings to provide high contaminant removal.
Greensand media has been incorporated into countless filters due to its flexibility and efficient iron and manganese removal in both the municipal and industrial markets. this userfriendly media is commonly found in horizontal pressure filters , vertical pressure filters and in gravity filters where iron is the primary contaminant to be removed.
Greensand plus is a manganese dioxide coated silica media designed for the removal of iron, hydrogen sulfide and manganese from water. it is a direct replacement for manganese greensand and has a number of advantages. available in 12 cubic foot bags and bulk quantities.
Greensand plus is inversands latest filter media for removing iron, manganese, arsenic, radium and hydrogen sulfide. first and foremost, filter media is merely one component of a complete filtration system. it is not the beall, endall that will make or break a system.

H2k industrial sand filters are designed to remove larger suspended solids 50100 microns, using a single size of filtration media. the coarseness of the filtration process can be determined by adjusting the size of the filter sand. the effective size of each granule of sand typically varies from 0.35mm 1.2mm.
If chlorine andor kmno4 are used for prefilter oxidation of iron, the run time can be extended for higher iron levels with the addition of an anthracite layer on top of the greensand media. a primary concern is to not trap too much ferric hydroxide within the greensand because you can have precipitated iron coming through and a much greater.
