The Treatment of Food Processing Wastes ; '^^ , R- J- DOUGHERTY i '' ' " Sanitary Engineer '^ _ ¦ ') - H. J. Heinz Company Pittsburgh, Pennsylvania The food industry, like others, has come to the realization that industrial waste treatment is a real item of production cost. Consider¬ able effort and interest is being given to reducing the cost of this phase of production, particularly in competitive product fields. In addition to the economic considerations it has been learned that all too often this phase of production has considerable importance to the company in terms of public relations, both in the factory community and in the area where its products are sold. Consumer resistance to a product as a result of adverse publicity is serious and difficult to alleviate. The engineer's problem is to provide effective treatment at a mini¬ mum cost. Effective treatment Is attainable by: (1) lagooning and land irrigation, (2) chemical precipitation, (3) biological treatment, (4) combined treatment with domestic sewage. Also, there are under Investigation two other methods which are believed to have definite possibilities, they are: (1) anaerobic digestion and (2) accelerated activated sludge. The method of treatment used will be dependent upon: (1) the degree of treatment required to protect the receiving stream, (2) the ultimate disposal of the effluent, and (3) the cost, which Is most important to the management. This paper will not attempt to tell how food wastes should be treated, but will relate some of the experiences in meeting the problems and to relate the information developed on methods not now in general use. Lagoons and land irrigation—For the small seasonal canner this is best and the least costly method of treatment and disposal, providing: (1) there is sufficient land area available, (2) the topography and character of the soil is suitable, (3) the location is isolated from popu¬ lated areas and the factory, and (4) the time of year, duration of operation and volume of flow is consistent with the other factors. 479
