The use of the activated sludge process to treat wastes arising in a 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 was 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. The polyelectrolyte C-32 produced by the Dow Chemical Company was found to enhance the filterability of high-solids activated sludge, and to produce an effluent of good quality for the growth of Chlorella pyrenoidosa 71105.
