Multi-port valve blocks: Generation of ultra-pure water - Ion exchanger, reverse osmosis and electrodeionization


As a world leading manufacturer of complex multi-port diaphragm valves made of stainless steel, GEMÜ has earned an excellent reputation in the Biotech and Pharmaceuticals markets. The skills and experience that GEMÜ has gained are now transferred to industrial applications and the company now designs and manufactures multi-port valve blocks from plastic materials. Combining the subprocesses of softening by ion exchange, reverse osmosis and electrodeionization is considered today to be an established procedure for generating pure and ultra pure water in the pharmaceutical industry. BWT Pharma & Biotech GmbH OSMOTRON PRO 1800 HPW‘s pure water treatment plant unites these three treatment steps in one system.
