The Use of Biological Waste Treatment Systems for the Stabilization of Industrial Wastes ROSS E. McKINNEY Assistant Professor of Sanitary Engineering Massachusetts Institute of Technology Cambridge, Massachusetts The economic disposal of dilute organic wastes is one of the major problems facing industry today. The volume and the nature of the organic wastes being produced by many plants are such that the receiving body of water is not able to assimilate the wastes without creating nuisance conditions. Municipal sewage treatment plants are not always available or of sufficient capacity to handle both the domestic sewage and the industrial wastes. In either case the industry must reduce the strength of its organic wastes to such an extent that the wastes can be satisfactorily disposed into municipal sewers or to a receiving body of water. Biological treatment is the most efficient method for reducing dilute organic wastes since it is possible to obtain any degree of purification required. Unfortunately, it is not always easy to decide on the best type of biological treatment for a particular industrial waste. It is the purpose of this paper to briefly set forth the characteristics of the major biological waste treatment systems as a guide in the selection of the proper treatment units. The four biological treatment systems in operation today are anaerobic digestion, oxidation ponds, trickling filters and activated sludge. The basis for all four systems is the same. The microorganisms in each system utilize the organic matter in the wastes for the production of new cells and for energy to remain alive. The organic matter which has been converted into new cells has not been completely stabilized but merely transformed from one chemical structure to another. The organic matter which has been utilized for energy and converted into carbon dioxide and water has been completely stabilized. It can readily be seen that the two problems in biological waste treatment systems are the removal of the organic matter from the waste waters and the removal of the microorganisms which have been created in the first phase. 465
