A new approach to sewage treatment which involves rapid clarification of raw sewage with fine magnetite particles is described. The process, which is essentially a greatly accelerated chemical coagulation, provides a quick separation of the sewage into two liquid streams, one clarified, the other highly concentrated. Development of the process up to and including operation of a fully continuous pilot is outlined and potential advantages and disadvantages identified.
Keywords: Sewage; clarification, adsorption, coagulation, magnetite; magnetic flocculation, regeneration, sludge treatment.
