Evaluation of Flow Equalization in Municipal Wastewater Treatment

摘要

This study was conducted to analyze the impact of flow equalization on the operation and performance of municipal wastewater treatment plants. Objectives of the study were: (1) Establish the effects of flow equalization on plant performance; (2) summarize current experience with design and operation of equalization facilities; and (3) summarize unit costs of equalization facilities and appurtenances. A national survey identified facilities and provided detailed information on design; operating practices; and construction, operation, and maintenance costs. Quantitative effects of equalization on plant performance were analyzed. Quantitative design methodology is presented for the sizing and estimation of costs for equalization facilities.
