Application: H2S Reduction
This is model 28F21750GSF from our MF-400 Series.
Water that contains too much iron, manganese, and hydrogen sulfide in it can cause a smell, discolor, or taste. In water filtration, the proper way to treat this problem is with a green sand filter. A green sand filter is made up of manganese green sand or is more scientifically known as glauconite. Green sand filters require a pretreatment of an oxidizing agent first, chlorine works best when removing iron from water while potassium permanganate works best when dealing with manganese. Due to the pretreatment, when the water comes in contact with the manganese green sand, either the iron, manganese or hydrogen sulfide instantly oxidize. This means the impurities go from a dissolved state to clumps and then they become trapped in the filter media. As water continues to travel down the tube, iron, manganese, and hydrogen sulfide are removed down a different pathway. Regeneration of the green sand in the filter is necessary to continue quality and longevity in the usage of the filter.

Water Challenges: Hydrogen sulfide (H2S) is a gas that exists naturally in various groundwater sources. It is created through the decay of underground buildup from organic substances such as decomposing plant matter and is usually located in shallow wells. H2S can also infiltrate surface water since flowing water is naturally aerated, resulting in an unpleasant and distinctive smell. This water becomes unusable in many applications, including consumption due to poor quality. For this reason, green sand filters are depended upon to remove the minerals that cause these issues such as iron and manganese from well water.
