Abstract Generalized estimates of both performance and cost are presented for wastewater treatment processes which can be used with activated sludge process to reduce the pollution load on the receiving stream. Processes and groups of processes believed to be leading candidates for use downstream of secondary treatment are listed. Data from various sources on the fraction of 5-day BOD associated with suspended solids are tabulated. Microscreening or rapid sand filtration removes about 42% of the 5-day BOD and 21% of the COD and TOC. Other solids-removing processes, such as lime clarification, multimedia filtration, and granular carbon adsorption, remove a greater fraction of the suspended solids. Some of the dissolved organic contaminants might be removed, but this appears to be negligible. A large fraction of the dissolved organic species is removed by granular carbon adsorption. Estimates of the concentrations of BOD, COD, TOC, nitrogen, and phosphorus downstream of each group of processes are tabulated. Estimated capital and operating and maintenance costs for each process are shown. (WRSIC abstract)
