Cutting-edge industrial processes

The Safran Electronics & Defense site at Domérat in the Allier department uses treated surface water both for fire protection purposes and for its industrial processes. In particular, it is used in cooling processes and in the cleaning and assembly of advanced electronic components and circuits.

The requirements in terms of treating the water used in these processes are both qualitative, to obtain ultrapure water, and quantitative, to optimise consumption and discharges, in order to improve the site's industrial, energy and environmental performance.

Since the early 1980s, BWT has dedicated a team of on-site technicians at SED, working closely with the Safran teams in place to implement and develop innovative solutions. These include ultra-filtration, softening, reverse osmosis and electrodeionization, which make it possible to obtain ultrapure water and 18 Megaohm water from surface water, of optimum quality for industrial electronics processes.

The assistance of the BWT technicians, who are continuously on site, with their in-depth knowledge of both SED installations and the BWT solutions implemented, are an invaluable asset in guaranteeing sustainable and effective water treatment solutions, and ensuring the monitoring of indicators and continuity of service for the entire site.

Thanks to a physico-chemical detoxification station, discharges into the natural environment are also better controlled and meet current regulatory standards. Eventually, SED hopes to deploy a zero-waste treatment plant, which would enable the site to stop collecting from and discharging waste into the natural environment.
