| Popis: | The technology of obtaining a coagulant—aluminum hydroxychloride—from aluminum chip by the alkali-acidic method is investigated. In this method, the largest part of impurities present in the starting raw material is separated during the filtration of the aluminate solution. The reagent for the removal of oils, petroleum derivatives, and lubricoolant from the surface of aluminum chip is selected. A new principal process flow chart for obtaining the coagulant by the alkali-acidic method is suggested. The flow chart allows one to obtain a coagulant with a minimal content of impurities with the simultaneous liberation of chlorine for water disinfection and sodium hydroxide for the alkali dissolution of aluminum chip. |
