Food processing plants have the capability of discharging up to 36 billion gallons of waste water annually. This liquid waste must be disposed of in a manner which decreases its strength to a level required by water regulatory agencies. Several variations of lagoon type biological systems using two lagoons in series have been investigated over a two year period. The results indicate that the semi-anaerobic-aerated and the forced aerated systems merit further consideration as efficient disposal methods. The open or facultative system serves only as a dumping place with settling as the primary treatment process. The BOD/COD relationships were studied and variations from the ratios reported in the literature were observed. In the anaerobic and open systems the BOD/COD ratios were approximately 1.0 or greater. In the forced aeration units the ratio was considerably less than 1.0. The possibility exists that these values could be of assistance in determining the conditions of the lagoon.
