METHOD FOR OBTAINING OF REAGENT FOR WATER TREATMENT

摘要

A method for obtaining of reagent for water treatment comprises the preliminary baking of caoline raw materiald and its decomposition with sulphate acid followed by product drying. Starting caoline clay is baked at temperature of 500-510 °С during 44-46 minutes; for decomposition by sulphate acid dilute sulphate acid with concentration of 34-36 % is used; obtained product is dried at temperature of 110-115 °С. After drying the reagent is kept in environment with relative humidity less than 70 % during 7 days.
