Purpose - to study the influence of pH, filtering speed and degree of saturation of oxygen to clean underground water containing elevated concentrations of iron and manganese, as well as defining the technological conditions applying sorbent-catalyst in local water treatment plants. Methods - spectrophotometric method pH-measurement by the statistical analysis methods. Main results - the processes of natural underground water purification of manganese in free-flow filter settings and types of pressure loaded sorbent-catalyst filter with linear speeds from 3.1 to 10 m / h. The best results from a technological and practical point of view was obtained at a pressure filtration installation type. Layer loading height is 0.86 m, linear filtering speed 3.0 - 3.5 m / h. Monitoring the installation work carried out within 1 year. The total volume of treated water per year was 103 m3 wash mode filter demanhanatsiyi - 1 time per week. Manganese compounds in the leachate were found. Technology demanhanatsiyi water using sorbent-based catalyst to control hryazoyemnosti and timely washing filter and can be used in water treatment.
