COST-EFFECTIVE TREATMENT TECHNOLOGIES FOR REMOVING CECS
Speth, T., U.S. EPA Tools and Resources Webinar Series, 40 slides, March 2019
Treatment technologies for three contaminants of emerging concern-PFAS, cyanotoxins, and perchlorate-were presented in this webinar with an emphasis on determining cost-effective solutions for small systems. Specifically, how contaminant properties influence treatment effectiveness, operational complexity, cost, and residual stream handling were discussed. Also, novel technologies were discussed using anaerobic biofiltration of perchlorate and nitrate as an example, and a demonstration of the impact of system size on capital and operating costs was shown. For each technology and contaminant, how to avoid unintended consequences, such as increased water corrosivity or residual handling problems, was covered. https://www.epa.gov/sites/production/files/2019-03/documents/2019-03-20_cec_treatment_state_webinar.pdf
