The use of the activated sludge process to treat wastes arising in remote environment appears to be feasible if the process can be successfully miniaturized. A major problem in the development of equipment utilizing the process is the continuous separation of effluent of satisfactory quality. A method devised for pre-treating the mixed liquor with polyelectrolyte coagulants to aid in phase separation. The effect of coagulants on the metabolism of algae was also evaluated.
