Comparative effectiveness of titanilsulphate, aluminiumsulphate (AS), based sulphate (BSA 2,0 ) and based chloride (5/6 BCA) of aluminium depending on pH (8,0 – 6,3) and alkalinity (5,0 – 2,0 mmol/L) under removing fluorine from water has been studied. The fulfilled researches indicate about the higher effectiveness of BSA 2,0 and 5/6 BCA in comparison with SA under removing fluorine as well as special aimed decreasing pH and alkalinity that provide the decreasing of reagent expenditures and the obtaining water of necessary qualities. It is shown that the using of titanilsulphateunder fluorine removing is perspectiveless.
