Abstract

As part of the planning process for design and construction of advanced treatment facilities at the Sacramento Regional Wastewater Treatment Plant, demonstration-scale pilot facilities evaluated alternative advanced treatment processes needed to meet new NPDES discharge permit limits. The test facilities consisted of a biological nitrogen removal (BNR) activated sludge treatment process, parallel membrane and granular media filtration processes and a biologically active filter preceded by ozone treatment, and three parallel disinfection processes (free chlorine, ozone, and UV irradiation). Twelve trace organic indicator compounds were selected for study. The report summarizes the performance characteristics of common biological treatment processes, filtration technologies, and disinfection technologies in reducing trace organic compounds.
