Del Rio water treatment plant retrofitted with hollow-fiber ultrafiltration cartridges

Sponsored by


WILMINGTON, MA, June 13, 2014 -- Koch Membrane Systems, Inc. (KMS), a developer and manufacturer of innovative membranes and membrane filtration systems, recently announced it has successfully launched the initial phase of its retrofit to the ultrafiltration (UF) system at the City of Del Rio's water treatment plant located in Del Rio, Texas. The full retrofit project is scheduled to be completed over the course of a year.

In 2003, the city commissioned a new Aquasource brand UF membrane filtration plant in response to the Interim Enhanced Surface Water Treatment Rule (IESWTR) and recommendations by the Texas Commission of Environmental Quality (TCEQ). By 2011, the plant's original UF membrane cartridges were showing signs of wear, requiring frequent fiber repairs. Ultimately, the cartridges were determined to have reached the end of their useful life and needed to be replaced.

Replacement costs utilizing the existing specified membranes were beyond the facility's operating budget, forcing the City of Del Rio to pursue a retrofit project, initially with little success. Most of the UF membrane companies contacted could either not match the footprint of the existing cartridges, or the quoted expense for the retrofit project was cost-prohibitive to take on.

Following successful testing of Koch Membrane's TARGA II UF membranes, it was determined that a retrofit could be implemented with minimal modification to the existing system. KMS system designers were able to provide prefabricated rack inserts including manifolds, connectors and membrane cartridges that fit within the existing rack framework and utilized existing system controls. KMS also provided installation and startup assistance.
