The aim of this work is selecting the optimal method for the purification of groundwater with different acidity and alkalinity from iron compounds and ammonium.

Research was conducted in production conditions on groundwater containing iron compounds and ammonium.  Waters belong to different classes of acidity, alkalinity and organic matter content. The research examined the effect values of pH and alkalinity on the number of iron bacteria colonies in a unit volume of water. The dependence was studded of the effect of alkalinity, pH, and contact time on the process of oxidation of ammonia by iron bacteria. The kinetics of the oxidation of organic compounds and ammonia consortia of microorganisms is studied. It is shown that the planned stops of water treatment equipment for more than three hours, there is the deterioration in the efficiency of its operating. It is connected with the development reducing bacterias of sulfate and iron in the in the filtration leyer. This process leads to the restoration of the pre-oxidized iron and the formation of nitrogen gas as a result of normal oxidation of ammonium. The process was studied, investigated the simultaneous biochemical oxidation of iron compounds, ammonia, dissolved organic at current iron removal station in bioreactors. The mechanism of biological oxidation of these compounds is shown. We carried out the spectral analysis of the biofilm from loading granules of bioreactor.

Based on the research and developed the theory of the mechanism of biological oxidation of iron compounds and ammonia, we develop, designed and recommended for introduction groundwater treatment technology.

Keywords: oxidation, iron bacteria, bioreactor, bio-physical and chemical cleaning methods, the Fenton reaction
