Object of investigation - manganese oxide-carbonate ore, dolomite (Dnipropetrovsk region., Ukraine) and sorbents, catalysts for the removal of water manganese compounds developed on its basis; clay mineral saponite (Khmelnitsky region., Ukraine) and sorbent for the removal of fluoride ions from water; Purpose - to create selective sorbents to remove fluoride from the water, the rationale for ways to improve the catalytic activity of catalysts, sorbents for iron removal and demanhanatsiyi. Main results - The processes of purification of natural underground water of manganese in free-flow filter settings and types of pressure loaded IC, the linear filtering speeds from 3.1 to 10 m / hr. The best results from a technological and practical point of view was obtained at pressure filtration installation type. Established that the joint removal of iron and manganese compounds sorbent-catalyst of water, increased concentration of iron compounds above 1 mg / dm3 disrupts sorbent catalyst to remove manganese compounds. The difference in the mechanisms of metal oxidation Fe2 + and Mn2 + leads to the formation of several functional areas within a single filter cleaning downstream water cleared. Proskok compounds of manganese in the filtrate was caused by a decrease in net volume through the filter block active centers of the surface Insurance iron compounds. The technology of underground water purification compounds of iron and manganese. Technology demanhanatsiyi water using sorbent-based catalyst to control hryazoyemnosti timely and washing the filter. Sorbent-catalyst needs no regeneration of the chemical reagents. Scope - water treatment and water treatment.
