An investigation was carried out on the potentials of Alkaleri and Kankara kaolin for the production of aluminum sulphate using sulphuric acid (H2SO4) solutions. The kaolin samples were beneficiated and calcined at 700 o C for 7 h to obtain meta-kaolin. The aluminum contents in meta-kaolin were extracted using varied concentration of H2SO4 ranging from 30-50 % in the increment of 5%. Results obtained revealed that the produced aluminum sulphate were effective in treating Gubi-Dam raw water. Performance evaluations of various parameter tests indicate the superiority of the produced products over the commercial aluminum sulphate and these parameters fell below the World Health Organization Standard. Aluminum sulphate samples produced using 40 % and 35 % H2SO4 gave the best performances for Alkaleri and Kankara clays respectively. Therefore, Alkaleri and Kankara clays can be used to produce aluminum sulphate within the experimental limits used in this study. Keywords:Beneficiated;Calcined;Kaolin;Sulphuric acid; Coagulant aid
