NANOPARTICLES OF ALUMINIUM SALTS HYDROLYSIS PRODUCTS IN WATER TREATMENT AND DISINFECTION

摘要

The size, surface area, electrokinetic potential, hydration, as well as rate and degree of aggregation of aluminium salts hydrolysis product particles (HPP) as a function of salt dosage, pH, alkalinity, water ionic strength, and 0H/A1 ratio in the salt molecule has been determined. A relationship between surface characteristics and the degree and mechanisms of HPP aggregation is established. The efficiency of aluminium salts HPP in removal of dispersed particles and bacteria from water is demonstrated. A new method of electric spark discharge for producing aluminium-hydroxide HPP and its use in water treatment is described.
