Title: Next Round Brewing
To Inspire and promote dialogue about diversifying our nation’s water portfolio and the importance of reuse water, the Clean Water Professionals of Kentucky and Tennessee and KY/TN Section of American Water Works Association started a challenge called Next Round Brewing. The challenge was to produce high quality micro-brews using recycled water from the Floyds Fork Water Quality Treatment Center in Louisville, KY. Louisville MSD, Louisville Water Company, Isopure Corp, and University of Louisville have collaborated with four local microbrewers, Gordon Biersch, Holsopple Brewing, Akasha Brewing and Apocalypse Brew.
To identify the best design for a robust water purification system, Next Round was proposed as a capstone project for seniors in the UofL’s chemical engineering department. Five teams of four students were tasked with the design of chemical and physical processes, accounting for the challenges associated with process scale and evaluating economic viability of process. Selected treatment units were combined into the Next Round purification system and Isopure Corp, the world’s leading manufacturer of FDA-registered equipment for dialysis water treatment, constructed the scaled-up system.
The Next Round water purification system includes PAA disinfection, micro filters, UV lights, activated carbon filters, Nano filters, and Ozone injector. This robust system was then operated and examined comprehensively at the Floyds Fork treatment center. The ideal operational performance of the system was constantly examined and monitored during two month of pilot study. The quality of produced recycled water was repeatedly examined by Beckmar and LWC laboratories for selective drinking water standards. Finally, 2000 gallons of recycled water were produced and delivered to brewers.
The special edition beers were served during the Water for Life event at August 18th at the Louisville Waterfront Park. Several people enjoyed the beer, had a conversation about value of water, and found a new appreciation for something most of us take for granted.
Next Round Brewing received significant media coverage from WFPL, WDRB, WHAS, and UofL news. For more information, check out our story on YouTube
