Membrane manufacturer Koch Membrane Systems has started the initial phase of its retrofit to the ultrafiltration system at a water treatment plant in Del Rio, Texas.
Following successful testing of Koch Membrane Systems’ TARGA II UF membranes, the firm determined that a retrofit could be implemented with minimal modification to the existing system. Koch has provided prefabricated rack inserts including manifolds, connectors and membrane cartridges that fit within the existing rack framework and used existing system controls.
The full retrofit is scheduled to be completed in a year.
The plant was commissioned in 2003. By 2011, the plant’s original UF membrane cartridges were showing signs of wear, requiring frequent fibre repairs. They have now reached the end of their useful life.
