Greensand Whole House Filter

Large Whole House Manganese, Iron and Hydrogen Sulfide removal Water Filter, also known as Whole House Greensand Water Filter. This filter contains media derived from naturally mined ore of manganese dioxide which has been used in water treatment for more than 75 years. Regenerating media that can remove iron from drinking water. Nothing is imparted into the drinking water and it has a high capacity for low contaminant concentrations, and can be used in conjunction with aeration, chlorination, ozone or other pre-treatment methods for difficult applications. Chlorine or other oxidants accelerate the catalytic reaction.

 

This product is an old technology that has now been replaced with Iron and Hydrogen Sulfide Removal System. New systems don't require regeneration.

Greensand Iron Filter uses naturally mined media CQ-IGS to reduce iron. Dissolved iron gets oxidised by media, which causes precipitation of the minerals and any iron, manganese or hydrogen sulfide present in your water supply. Precipitated contaminant then is trapped by the media and gets backwashed, while the end result is clean filtered water.

 

With proper installation, greensand filters have a capacity to reduce the following contaminants:

10 ppm (parts per million) of both ferric (oxidized) and ferrous (clear) Iron

5 ppm of Hydrogen Sulfide (rotten egg odor)

5 ppm of Manganese

For best performance, the Greensand System requires pH to be in the range of 7.5 - 8.5, and for best Manganese removal pH is 8-9.

Water goes through 3 stages of filtration.

In Stage 1, water flows through a 20"x2.5" sediment pre-filter that removes sediment, dirt and silt. This water filter also extends life of the main unit

In Stage 2, water flows through a large 5' mineral tank that contains Manganese, Iron and Hydrogen Sulfide reducing Greensand-derived media.

In Stage 3, water flows through a 20"x2.5" solid carbon block filter cartridge. Carbon (also called Charcoal ) has been used in water filtration for centuries. It effectively removes or reduces many contaminants including Volatile Organic Compounds ( VOCs ), insecticides, pesticides and industrial solvents.

System comes with Poly Glass mineral tank field with Manganese, Iron and Hydrogen sulfide reducing media, 2 20"x2.5" filter housings for sediment pre-filter and carbon block post filter, Fleck microprocessor for backwash control, and installation hardware.

 

Note: system is designed for water pH levels between 7.5 and 9. If pH is between 6.5 and 7.5, consider a higher capacity Iron, Hydrogen Sulfide and Manganese filtration system. If pH is lower than 6.2, you will need to neutralize it before iron removal system can be used. Here's a good whole house acid neutralizer system.
