Description:
THE USEPA's Environmental Technology Verification for Metal Finishing Pollution Prevention Technologies (ETV-MF) Program verifies the performance of 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 testing is conducted under strict EPA quality guidelines in metal finishing shops under actual operating conditions. This paper summarizes the verification test results for two alkaline cleaner recycling technologies: microbial digestion and microencapsulation. Following this summary, verification of a cross flow microfiltration technology for an alkaline cleaner bath is discussed in detail. The test methods, data analysis, and conclusions are presented, including the environmental and economic benefits of this technology. The data indicate that this technology is effective in removing organic soils from the bath while preserving the chemical constituents.
