Brehm Chirurgie-Mechanik e.K.: Efficient preparation of DI water for cleaning implants
Peter Brehm Chirurgie-Mechanik e. K., based in southern Germany, produces implants and instruments for artificial joints made from the most advanced materials. To date, a mixed bed ion exchanger has been used to produce DI water, which meant that the water quality needed to be tested each time that the cartridge was changed, so Brehm contacted EnviroFALK’s experts to discuss the problem.
Following in-depth analysis and consultation they came up with a water treatment system consisting of reverse osmosis followed by electrodeionisation (EDI). This system produces DI water with a consistently high water quality of 0.06 µS/cm. The microbial load is below 20 cfu/ml and endotoxins are below 0.01 EU/ml.
Dr. Rolf Schreinert, Product Manager at EnviroFALK: “The intermittent water consumption was the real challenge, so we decided to produce only small amounts of DI water that are then stored under an almost sterile atmosphere and treated with UV radiation. This allows larger amounts of high-quality DI water to be drawn any time.” The DI water is needed for final cleaning of implants, which are made of cobalt-chrome, titanium, polyether and PEK.
