GREENDSAND FILTERS

iron and manganese removing systems

Manganese greensand is made of zeolite with similar characteristics to ion exchangers. In order to oxidize and then remove materials like iron or manganese it has to be treated with potassium permanganate solution. This filter media performs very well, eve if there are higher concentrations of iron, manganese, etc. The pH range should be between 7 and 8, at least 6.5, for effective removal. Hydrogen sulfide is not a source of problem and will be sufficiently eliminated. For higher concentration in the raw water, it is favorable to have a continuous potassium permanganate (0.3% solution) injection instead of regeneration.
