Brehm Chirurgie-Mechanik: Deionized water for cleaning implants
Brehm Chirugie-Mechanik opts for EnviroFALK water treatment for the production of implants.
Peter Brehm Chirurgie-Mechanik e. K. in Franconia manufactures implants and instruments for artificial joint replacement using state-of-the-art materials. Previously, a mixed bed ion exchanger was used to produce demineralized water, which meant that an additional qualification of the water quality had to be carried out after each cartridge change.

Ultrafiltration and reverse osmosis
Challenge for the customer
Discontinuous water consumption.
Dr. Rolf Schreinert, Product Manager, from EnviroFALK: “The challenge was the discontinuous water withdrawal. We therefore decided to produce small quantities of demineralized water and store it in a low-germ atmosphere using UV treatment. This means that individual quantities of high-quality water can be called up at any time as required.” The deionized water is required for the final cleaning of the implants, which are made of cobalt-chrome, titanium, polyether and polyether ketone.
Brehm then sat down with the experts from EnviroFALK. After detailed analysis and consultation, a water treatment system consisting of reverse osmosis and downstream electrodeionization (EDI) was designed. The system produces deionized water with a consistently high water quality of 0.06 µS/cm. The bacterial load is less than 20 CFU/ml, the endotoxin values are less than 0.01 EU/ml.
- Demineralized water of consistently high water quality
- The bacterial load is below 20 CFU/ml
- The endotoxin values at less than 0.01 EU/ml
The system produces deionized water of a consistently high quality. The customer is very satisfied.
