Abstract

The objectives of this study were: (a) to determine if aeration of secondary treatment plant effluent will enhance wastewater quality; (b) to determine the most satisfactory detention times if aeration is feasible; (c) and, to determine if there is an advantage to operating aeration basins in series. To accomplish the objectives of this study a pilot plant was designed on a continuous now basis and then constructed at the Brookings wastewater treatment plant. Preliminary batch studies were made during the summer of 1967 to find the general ranges of the parameters used in the analyses. No definite values could be determined at that time because only one fifth of the student body was living_ on campus and consequently the waste flows were at a minimum. The main study utilizing the pilot plant with continuous flow was run in October and November and was divided into three testing periods. For each period the detention time and number of analyses varied. The analyses of the influent, reaction basins, and effluent samples consisted of chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), and volatile suspended solids (VSS).
