METHOD FOR PREPARATION BASIC ALUMINIUM SULFATE

摘要

The invention is in the field of chemistry and can be applied in the abstraction of base aluminium sulphate that can be used in cleaning draining water, in the paper making industry or in other areas instead of regular aluminium sulphate. The goal of the invention is to shorten the time of the process. The proposed goal is achieved by pouring the aluminium hydroxide pulp (suspension) into concentrated sulphuric acid. The mixture is mixed by the compressed air coming out through the valve. To ensure the abstraction of the base aluminium sulphate, surplus aluminium hydroxide is needed.
