Abstract
The invention relates to the technology of inorganic substances, in particular to the production of aluminium sulfate, which can be used in municipal economy and industry for purification of potable and wastewaters, and also in production of catalysts and adsorbents. The purpose of the invention is a process for preparation of coagulant –basic coagulant aluminium sulfate by sulfatisation of aluminium hydroxide with subsequent crystallization of ready product. Performing sulfatisation process in autoclave conditions with use of sulfuric acid and dilution of product before crystallization provides reduction of heat costs, acceleration of the process for preparation of coagulant with saving the yield thereof.
