In-tank aeration reduces disinfection byproducts to help utilities achieve Stage 2 compliance
PAX Water Technologies will unveil the Trihalomethane Removal System (TRS) at the AWWA Annual Conference and Exposition (ACE ‘12) in Dallas, Texas. Designed in partnership with Utility Service Company Inc., the largest tank asset management company in the United States, TRS is a custom-designed aeration system for storage tanks that removes trihalomethanes (THMs) from drinking water to help utilities comply with the EPA’s Stage 2 Disinfectants/Disinfection Byproducts Rule. The product will be featured at the ACE ‘12 New Product Technology Showcase.
THM is a suspected carcinogen and a volatile type of disinfection byproduct that can be naturally removed from water through aeration, or infusing water with air. By using proprietary design and modeling software, PAX Water is able to compare the relative performance of different aeration technologies and create designs that achieve predictable levels of THM reduction while ensuring maximum energy efficiency. This approach enables PAX Water to accurately predict the effectiveness and operating cost of an aeration system before it is built so that utilities can select the most cost-effective TRS for each storage tank.
“The Stage 2 D/DBP Rule is already on our doorstep, and municipalities across the United States are looking beyond costly treatment plant upgrades to achieve compliance,” said Dr. Peter S. Fiske, CEO of PAX Water Technologies. “With TRS, utilities can target trihalomethane removal where it is most needed: inside their storage tanks. The key is to custom-design the aeration system for each tank’s unique operating conditions—delivering the right level of trihalomethane reduction with the lowest possible energy footprint.”
Additionally at ACE ‘12, Dr. Fiske will be presenting “Biomimicry: A Resonant Theme for Winning Back the Public's Trust in Their Drinking Water” on Tuesday, June 12, 2012 at 11:30 a.m. Dr. Fiske’s presentation is part of the conference session Communicating the Value of Water Part 1: Educating Your Public. PAX Water has been awarded the ACE ‘12 Green Ribbon Award for its sustainability initiatives and will be exhibiting at booth 2142. Utility Service Company will be exhibiting at booth 2026 and will be available to discuss the successful results of TRS case studies.
