Title: Advantages claimed for DOW EDI membranes

No Leakage: DOW™ EDI modules are reliably sealed with high pressure top and bottom end caps eliminating leakage problems commonly associated with plate and frame design. Low Maintenance: Unlike plate and frame EDI systems, DOW EDI modules do not require tightening of nuts and bolts at installation or the retorquing of bolts on an ongoing basis to prevent leaks. Light Weight Modules, Modular, Easy Access Designs: The DOW EDI modules result in very modular systems that allow easy access and the light weight modules are easy to work with, no special lifting devices are required. Each module comes complete with an individual permeate sample port. Quality Control: Each DOW EDI module is performance and pressure tested prior to leaving our factory for trouble free start-up and operation. Cost Effective: The spiral wound DOW EDI modules allow system integrators to build systems that have both lower capital and operating costs when compared to plate and frame EDI devices and is truly a cost-effective replacement for conventional mixed bed ion exchange.
