"This study was undertaken to determine the effect of a continuous low temperature on the operation of a waste stabilization lagoon and to provide information of value to the sewage treatment field.

The investigation was conducted using two experimental lagoons subjected to a continuous illumination of 550 to 600 foot candles emitted by two fluorescent light fixtures. Of these units, the Cold Room Lagoon was maintained at a controlled temperature of 5° C. and the Warm Room Lagoon was operated at room temperature in the range of 16 to 32° C.

Dissolved oxygen and biochemical oxygen demand determinations were the primary parameters used in this study. In addition pH, suspended solids, and coliform bacteria determinations provided additional information of value.

Several different loadings of raw sewage were applied during the early phases of the investigation to establish the appropriate loadings for this study and to enable the acclimatization of the units. During the main portion of the study 16 fluid ounces of raw sewage were added daily to the Cold Room Lagoon resulting in a BOD loading of 11.3 pounds of BOD per acre per day and 32 ounces were added to the Warm Room Lagoon providing a loading of 22.3 pounds of BOD per acre per day.

It was found that waste stabilization lagoons operated effectively under a continuous low temperature but had a decreased efficiency and required reduced organic loadings"--Abstract.
