By the example of the reconstruction of the Uzyn water supply system treatment facilities it is given the grounds for biological factors use in water treatment systems for deferrization and removal of  excessive nitrogen and silicon compounds from groundwater. It is shown the feasibility field for the use of biological systems of deferrization depending on pH, Eh, rH.

Key words:  removal of iron from water, Pourbaix diagrams, iron-bacteria compounds, iron, biological removal of iron, oxidation-recovery potential, redox potential, silicon.

The article presents an overview of physical and chemical transformations of various forms of iron which are typical for groundwater. As factors that influence the form and contents of iron, the presence of oxidants, pH, redox potential, ionic composition of water and the presence of organic compounds ( mainly humic substances) are considered.

Keywords:  iron, oxidation, pH, redox potential, humic substances.
