Reducing residual aluminium concentration in drinking water at the Yaroslavl South water treatment plant

Summary

The aspects of elevated residual aluminium concentrations in drinking water at the Yaroslavl South water treatment plant are considered. On the basis of analyzing the data on water quality the effect of separate parameters on the residual concentration of aluminium was revealed. The experimental results of investigating the Volga river water treatment with the use of different coagulants and flocculants are presented. The expediency of replacing aluminium sulfate and Praestol-650 flocculant with aluminium oxychloride coagulant in cold seasons is shown.
