WILMINGTON, MA, Aug. 10, 2009 -- Koch Membrane Systems Inc. (KMS) a pioneer in membrane technology, filtration systems, system design and process expertise for nearly half a century, has been selected to provide a seawater reverse osmosis (RO) system for Minera Esperanza's copper-gold mine, at Michilla Port, Chile. The overall project, which was awarded to Nicolaides S.A., will provide drinking water to the mining camp. Construction of the system is expected to be completed in the fall of 2009.

"By using a seawater reverse osmosis system, Minera Esperanza can provide a safe and plentiful water supply to its workers," said Sergio Ribeiro, KMS' Commercial Director for South America. "The system has a number of features that make it ideal for this site, including its small footprint, lower power consumption due to an energy recovery device, high productivity and excellent permeate quality."

Koch's MegaMagnum® RO system.
The project consists of two MegaMagnum® RO MM2 equipment skids with a total of 20 MegaMagnum seawater elements. The water supplied to the copper-gold mine begins with seawater drawn from the Pacific Ocean. The seawater is pumped for about a mile to a water treatment unit and then through the RO system. The final permeate is disinfected with chlorine, making it acceptable for drinking water. The permeate flow rate is 520,000 gallons per day; maximum feed total dissolved solids (TDS) is 45,000 ppm; and the required chloride concentration is less than 250 ppm in the finished water.

MegaMagnum elements are the standard for large diameter RO projects. Among the many benefits of the KMS design are significantly reduced footprint, project costs, and installation time. Since large diameter RO systems use one-seventh the number of elements compared to standard 8-inch systems, maintenance costs associated with connections and O-rings are reduced. KMS has made loading and unloading of MegaMagnum elements safe and easy with the use of a hand operated winch. Typically, it takes less time to empty one pressure vessel containing MegaMagnum elements than the comparable number of 8-inch pressure vessels.
