  • Iron removing Principles and applications Nobel Srl

    Brief description of the process. Iron can be contained in water as a dissolved matter or as a precipitate suspended. Obviously, the removal of suspended iron, normally consisting of ferric hydroxide, is not very complicated; it can be made by mean of a common mechanical filtration (mechanical sediment filters, sand dual media filters).
