The coagulation-flocculation studies using Ti[O.sub.2] suspensions in low strength and intermediate strength ionic solutions, with and without the addition of aluminum sulfate
, were carried out in different values of pH.
Therefore, for the treatment of the raw effluent from the stamping industry, where the average initial COD is 4,500 mg [O..sub.2] [L.sup.-1], the best removal of COD, color and turbidity was achieved when using 600 mg [L.sup.-1] of aluminum sulfate
