Description
Summary:Conventional secondary biological treatment processes do not provide the degree of wastewater treatment required for most water reuse applications, nor do they provide a completely satisfactory method for protecting natural waters from pollution by waste discharges. A process employing chemical clarification, filtration, and adsorption by activated carbon was developed and researched on pilot scale for the treatment of primary wastes. This physicochemical process is a major divergence from the concept of the more expensive tertiary treatment following secondary processes. The research revealed total organic carbon and biochemical oxygen demand removals of 95 to 97 percent, 90-percent phosphate removal, and 95-percent nitrate removal. Costs are about $0.16/1,000 gal (3.8 cu m), including amortization of the capital.
