Greatbatch: Consistently high water quality for the production of implants

Greatbach relies on EnviroFALK water treatment for cleaning medical implants.

Medical implants are repeatedly cleaned during the manufacturing process to remove processing aids. A detergent containing surfactants is used for the various cleaning stages, which must then be rinsed off without leaving any residue. Rinsing is carried out with water of various purity levels – from city water to permeate and demineralized water. Special attention is paid to the final rinses. They determine the purity of the components.

Challenge for the customer
Provide high-purity water with a constant conductance of less than 0.1 µS/cm and a TOC of less than 0.5 ppm.

zu den Verfahrenstechniken

The task at Greatbatch was to provide high-purity water with a constant conductivity of less than 0.1 µS/cm and a TOC of less than 0.5 ppm. In addition, a low-water process should be selected that enables “inline disinfection”. Interventions in the closed water cycle, such as changing filters, were rejected. Standard components such as activated carbon, adsorbers or mixed-bed ion exchangers and particle filters could therefore not be included in the planning, as they have to be replaced after saturation with particles.

EnviroFALK designed a system solution made entirely of PVDF, consisting of permeate-staged reverse osmosis, modern EDI technology, ozonization and UV sterilization. The water treatment system continuously produces demineralized water of a consistently high quality. To reduce the bacterial count (CFU) and endotoxins, the water is permanently looped.

  • The water treatment system continuously produces demineralized water of a consistently high quality.

Geatbatch is very satisfied with the EnviroFALK water treatment system.
