What is The Removal of Manganese, Iron and Ammonium Nitrogen on Impregnated Activated Carbon about?

Intensive development of industry branches and agriculture causes a progressive deterioration of natural environment and a decrease in drinking water resources. Both in surface waters and underground waters, the increase in concentration of different elements and compounds which are dangerous for humans is observed. Unfortunately, the removal of these impurities by means of traditional methods is not always effective. Therefore, new, more and more efficient and modern methods of water treatment are searched for. In natural conditions, iron and manganese mostly occur in the form of hydrocarbons, sulphates, chlorides, combinations with humus compounds and sometimes in the form of phosphates. While getting into contact with air, these elements precipitate from water in the form of dark deposits, and water becomes turbid and dark-brown. The occurrence of these elements always creates some problems during water treatment. The occurrence of iron and manganese causes that water-pipe network to become overgrown. At much higher concentrations, both iron and manganese also have disadvantageous influence on people and animals. What is more, over-concentration of ammonium nitrogen accelerates
