Alkaline Cleaner Recycling Using Microbial Digestion An Environmental Technology Verification-Metal Finishing (ETV-MF) Pollution Prevention Pilot Test Report

摘要

The ETV-MF Program, in association with EPA's Common Sense Initiative for the Metal Finishing Sector, is a pilot for verifying innovative, commercial-ready technologies designed to improve industry performance and achieve cost effective pollution prevention solutions. Test plans are developed cooperatively between CTC, EPA and the technology supplier. Verification is conducted under strict EPA quality guidelines in metal finishing shops, where possible, under actual operating conditions. This paper will discuss the verification testing of a cleaner recycling technology that uses microbial digestion to remove organic soils from the bath. The test methods, data analysis, and conclusions will be presented, including the environmental and economic benefits of this technology. The presentation will conclude with an update of the EPA ETV-MF program and the status of other verification test projects.
