Determine the Effects of Individual Wastewater Characteristics and Variances on Primary Clarifier Performance
Research Impact
WERF sponsored a one-year study quantifying the affects of certain wastewater characteristics and their variability on the performance of primary clarifiers. The researchers set out to provide a recommended procedure for determining the maximum performance efficiency for a primary clarifier given the wastewater to be treated and the ability to measure the benchmark primary effluent concentrations which primary clarifier designs should strive to achieve. The report offers justification for the use of chemically enhanced primary treatment for stormwater flows and emphasizes the need for design engineers to evaluate biological process loading calculations on primary effluent not plant influent because of the stabilizing affect of primary clarifiers on influent variability.
Originally funded as WERF project 00-CTS-2.
