Optimization of water treatment conditions with usage of aluminium sulphate and ferric sulphate was made with raw water containing high concentrations of natural aluminium. For optimization of coagulation conditions here were used the jar tests. The efficiency of aggregation was evaluated with the help of the degree and test of aggregation. In all water samples used, the total aluminium concentration was fractionated into nine forms. The high values of degree of aggregation and high portion of macro-, micro-, and primary particles were attained in optimally treated water samples using both types of coagulants. It contrasts to the portion of non-aggregated particles ranging in optimal treated water only from 3% to 7%. Fractionation of total aluminium proved that the removal efficiency of all Al fractions is very good.
