Abstract: Alums have been produced from kaolin clay using two processes of production: the base leached process and the acid leached process. Kaolin clay which has some quantity of potassium in it as part of its constituent members gave alum samples that have above the stochiometric value of 8.23% in it. The base leached process gave a yield of 29.20 ± 1.07% of alum using the raw kaolin and 31.87 ± 1.13% of alum using calcined kaolin clay. Also, the acid-leached process gave a yield of 47.35 ± 1.64% of alum using raw kaolin and 59.47 ± 1.32% of alum using the kaolin clay Kaolin was blended with aluminium rich material such as alumina (Al203) and aluminium scraps to bring the quantity of the potassium in the alums to the stochiometric values. X-ray flourescence technique was used for the elemental analysis of the alums. This technique is good for analysing solid samples without having to solubilise them. The coagulative activities of the produced alums and the commercially available alums were assessed using both domestic water and tannery waste water samples.
