Power plant operators around the world are upgrading traditional water treatment systems in an effort to improve the efficiency of plant processes and lower customer costs. Microfiltration membrane technology is a proven method of achieving this goal. At the International Water Conference (November 4 th-8 th) in San Antonio, Texas, topic experts Marvin Drake of the Indiantown Cogeneration plant in Florida and Dr. Ram Venkatadri of Pall will present a paper discussing the latest membrane technologies that can help power plants reduce costs and improve processes. The paper was also co-authored by Spence Wise and Narasimha Charan, both sales professionals at Pall.

The plant required the flexibility to use different combinations of makeup water, including surface water, treated municipal effluent, and high TDS (total dissolved solids) well water. “The need for improvements in water footprint along with continuous cost reductions has made the reuse of process and waste water in power plants increasingly important,“ said Dr. Venkatadri, global marketing manager at Pall. “The trend of the future is towards complete zero liquid discharge (ZLD) plants and the deployment of microfiltration and reverse osmosis technology has facilitated the implementation of ZLD schemes.” The Pall AriaTM system, a cornerstone of Pall’s water treatment solutions portfolio, utilizes unique hollow fiber membranes with outstanding regeneration capabilities that cost-effectively produce high-quality water. The robust fibers also help ensure consistent system performance and reliability. “Pall’s automated membrane system has functioned smoothly for over a year while treating challenging cooling tower blowdown water,” said Mr. Drake, plant chemist at Indiantown Cogeneration plant. “We are very pleased that the system has met all of our performance goals while making good on its promise of cost savings.”
