摘要： The present invention relates to methods of producing aluminium-containing coagulants based on ultra-high-basicity polyaluminium chlorides (PAC), with Al2O3 content of more than 15.0% (wt. %), relative basicity within 70.0÷75.0% and long shelf life of at least 18 months. The production method can create a wide range of concentrations of an aqueous solution of polyaluminium chloride and is particularly useful for obtaining high concentrations of this substance. Compared to conventional coagulant production processes, the processes described herein are unique since they do not require the use of aluminium metal as a starting material. The products of the process are suitable for use in the technology of drinking water treatment and wastewater treatment for various branches of industrial production.
