Beschreibung
Zusammenfassung:	The article has investigated the processes of water purification of sulfates when treating with lime, sodium aluminate or aluminum hydroxide. It has been shown that the efficiency of removing sulfates depends on the type and consumption of reagents containing aluminum and the method of pretreating aluminum hydroxide. The paper has determined the effect of after treatment by carbon dioxide or magnesite on the efficiency of water purification of sulfates, the degree of its softening, and residual alkalinity.
