The extensive way of industrial development and the rate of population growth determine the increase in the amount of drinking water consumed and the requirements for water treatment. Known and applied technologies for the industrial production of aluminum oxychloride coagulant used in reagent water purifi cation are based on high-temperature processes that require complex hardware design. The paper presents the results of studies on the production of basic aluminum chlorides by the microwave method. The experiments were carried out on a designed laboratory setup based on a microwave oven; data were obtained on the yield of aluminum polyoxychloride depending on the change in process parameters, duration, coeffi cient of effi ciency, and 36% concentration of hydrochloric acid solution. Studies of the use of microwave technologies in inorganic synthesis have shown the eff ectiveness of such technologies, a decrease in the reaction time, an increase in the effi ciency of the installation, and the absence of contact between the heating elements and the reaction mixture. The infl uence of sulfuric acid as a process activator substance, which positively aff ects the productivity of aluminum polyoxychlorides, has been established. The results of physicochemical studies of the synthesized samples and their coagulation properties are presented, which indicates the possibility of using microwave technologies in the inorganic synthesis of aluminum polyoxychloride coagulants.
