Abstract:

Following the installation of polyurethane panel diffusers at the City of Richland's treatment plant aeration basin, off-gas oxygen transfer efficiency tests were conducted to confirm design values for alpha and to observe any deterioration in diffuser performance after two years of operation. The measured values of alpha were lower than had been anticipated. It was determined that contributing factors to these lower values were increased plant loading stemming from changes in sludge management practice, lower SRTs, and the aeration basin geometry. It was suggested that the sloped walls of the aeration basin contributed to the lower OTE values than comparative measurements in straight-sided aeration basins.
