In this work, it is studied the influence of the pH of the waste in the coagulation with aluminum by conventional and electrochemical dosing. To do that, the speciation of aluminum as a function of the pH has been characterized, and this information has been used to interpret the results obtained in the treatments (by both coagulation methods) of a synthetic oil-in-water emulsion and an actual effluent of a door-manufacturing factory. Results show that a simple change in the pH of the wastes… CONTINUE READING
