DISCUSSION ON THE MECHANISM FOR REDUCING THE FLUORINE CONTENT IN WATER AND IMPROVING ITS QUALITY BY NATURAL CLINOPTILOLITE—POTASSIUM ALUMINIUM SULPHATE SYSTEM

摘要:

Abstract:

This paper discusses the feasibility and the mechanism for reducing fluorine content in water and improving its quality for drinking by the natural clinoptilolite—potassium aluminium sulphate system based on the theory of surface chemistry of the hetrogeneous coagulation and through tests and verification with different experimental methods.The process of exchange-adsorption reaction is discribed in detail and relevant chemi- cal equations have been given.A fluorine-removing water-supply station designed ac...
