The presence of Fe in water in concentrations higher than a few milligrams per liter gives water a flavor described as “metallic”. Fe is found in the water in its insoluble form (Fe hydroxides) which causes various problems during the use and exploitations of the water.

      Most frequent problems manifested due to the Fe presence in the water are: sedimentation in the switching pipe, enhancing the development of microorganisms, textile dyeing during the washing up, damaging the water-works, and, in the end, Fe hydroxides make it harder for other processes we use in the water, such as ion exchange.

     Fe removing is done in the filters under the pressure known as DEFERIZATORS, which filter filling is either quartz sand or dolomite. If it is filter filling that uses quartz sand, Fe oxidation must be done first – aeration in the so-called “mixer”.

     Other way for Fe removing is so-called contact oxidation on the special catalytic filter material without previous oxidation. They consist of filter column filled with special filter-catalytic compound that transforms Fe from its solvent form into dissoluble form and sediments it on the filter compound. Sediment Fe on the surface of filter compound can be removed from deferizator with a simple backflow washing, which results in low exploitative spending and high efficiency.
