Abstract

"The application of preaeration of sewage on the operation and design of waste stabilization lagoons was investigated and its effect on the permissible BOD loadings was determined to provide original and basic information of value to the sewage treatment field.

The investigation was conducted using two 15 gallon aquariums, one of which was designated as the Control Lagoon and the other as the Test Lagoon. These experimental lagoons were subjected to 12 hour diurnal light and dark cycles, provided by means of fluorescent light fixtures.

Raw sewage and aerated raw sewage were fed daily to the Control and Test Lagoons, respectively. Three different BOD loadings were used in this investigation ranging from 35 to 118 pounds of BOD per acre per day. The raw sewage was aerated for a period of four hours before use.

The primary parameter employed in this investigation was the BOD determination. In addition, the dissolved oxygen, suspended solids, pH, and coliform group determinations and a microscopic examination provided information of value to the studies.

It was found that preaeration was beneficial to BOD reductions for loadings above 59 pounds of BOD per acre per day but that at lower loadings preaeration had no appreciable effect on the reductions"--Abstract, page ii.
