A home water treatment system is the best way to remove manganese from yourdrinking water.
Air injection oxidation filtrationAir-injection oxidation filtration is the best treatment for well water containing iron,manganese and hydrogen sulphide (three minerals which often occur together).
Air-injection oxidation filters have an air bubble and water tank on top. As the waterpasses through the bubbles, the minerals (including manganese) oxidise. Theseminerals then become trapped in a bed of manganese green or manganese ore.
When the system is backwashed, the minerals are backwashed out of the media.
Air-injection oxidation can remove as much as 5 ppm of manganese from water.
Cation exchange
A cation exchange water softener will take out small amounts of manganese fromwater.
Cation exchange removes calcium and magnesium and other cations from thewater. The main goal of cation exchange is to avoid damage from hardnessminerals, but the process can also be used to get rid of small amounts of otherminerals, such as iron and manganese. If your water has high levels of manganesethen cation exchange is not the best solution.
Distillation
Distillation for removing manganese from drinking water.
In distillation water is heated until it boils and becomes vapour.Some minerals, suchas manganese, boil at a different temperature than water. They stay in the boilingchamber as the water passes through cooling channels, forming a separatecontainer.A cation exchange water softener can remove trace amounts ofmanganese in water.
Almost all impurities can be removed from water by distillation. But the problemwith this method is that the distillation process is very slow and can only be usedfor point of use applications, so it will not solve manganese problems throughoutthe home.
