There are several water treatment solutions that can be used to effectively remove manganese from drinking water. The overall results of these methods will depend on the concentration of manganese and the form of the metal. Since manganese is an aesthetic issue, it has a high chance of being detrimental to all water consumers.
Once you have tested the water and determined what type of manganese is present in the water supply, it can be eliminated by using a water treatment system such as:
Greensand Filters: Greensand filters effectively protect downstream equipment and effectively reduce mineral levels such as iron, manganese, and hydrogen sulfide. These filters do not experience any detrimental effects from chlorine feeds and have low wear rates, which extend bed life.
Birm Filters: Birm filters are high-efficiency filters that remove dissolved manganese and iron components from freshwater sources at a very low cost. These filters are sometimes used in conjunction with a pressurized water treatment system, such as reverse osmosis or gravity feed systems. Birm filters are a great benefit to companies due to the fact that they require no maintenance using chemicals, only periodic backwashing, durable materials, a wide temperature range, and high manganese removal efficiency.
Pyrolox Filters: Pyrolox filter media works by oxidizing manganese and iron in the feed water using a natural chemical reaction. The captured minerals are then filtered out of the filter bed during a backwash cycle.
Water Softener Systems: Water softener systems are an effective solution for reducing water hardness, but they are also an effective solution for removing small amounts of manganese and other metals. The water softening process utilizes ion exchange resins, where manganese and calcium are replaced with sodium. Afterwards, a backwash process can be implemented to eliminate manganese and other metals from the softened water filter resins.
Oxidation Filtration: Oxidation filtration injects oxygen into the water to eliminate impurities. While oxidation is a proven solution for removing iron from water, it requires the addition of chemical treatments such as chlorine to eliminate manganese.
