Aluminium sulphate used during the coagulation process is hydrolyzed in the water, forming polynuclear complexes. Aged aluminium solutions show different coagulation behaviour than that of freshly prepared solutions. The aim of presented research was to highlight the infl uence of the aging of aluminium sulphate solution on the turbidity removal from water. Obtained results reveal that using of optimal aging solution of coagulant improves the coagulation process. application/pdf
