ABSTRACT:
A method for the removal of dissolved and/or suspended solid wastes from the liquid effluent of an industrial plant subsequent a stepwise formation of flocs and precipitates with subsequent removal of same utilizing coagulating and floculating agents while simultaneously adjusting the pH of the treatment medium. Both ferric chloride, lime and aluminum sulfate are used as primary flocculants with their action enhanced by the use of suitable polyelectrolytes. A coagulant for starches and fats facilitate more complete precipitation of wastes. Means for carrying out the method include at least one clarifier with a special arrangement of baffles to enhance the formation of the flocs and precipitates. In a preferred mode of operation, liquid industrial effluent is first pre-treated with a cationic coagulant and cationic polyelectrolyte prior to the stepwise floc formation and pH adjustments.
