Brioche Pasquier entrusts Veolia with new wastewater reuse unit

French industrial pastries company Brioche Pasquier has partnered with utilities company Veolia to meet its wastewater reuse needs at its site in Les Cerqueux, France. The new installation, operational since September 2023, allows for the reuse of 3m3/hr of wastewater as cooling water for its cooling towers.

Brioche Pasquier has entrusted Veolia Water — a Veolia subsidiary specialised in water treatment for industries for over 30 years — with the implementation of a packaged treatment plant to reuse the wastewater it generates. Veolia will operate it for two years.

The facility, located at Brioche Pasquier HQ in the Pays de la Loire region, allows the manufacturer to be 100% compliant with water quality requirements in the food industry. Serving as a pilot unit for its other production sites, the water treatment solution is instrumental in Brioche Pasquier meeting its sustainable development goals (SDGs), limiting its impact on the water resource by reducing its consumption. Overall, this installation is said to save 85% of the drinking water used for cooling the factory, which represents 18,000m3/yr. The treated wastewater that is not recycled in the plant is used for agricultural irrigation.

With a capacity of 3,000L/hr, the facility features a customised pretreatment using filtration and a reverse osmosis (RO) stage including a Sirion Advanced Pro, allowing for the production of high-quality industrial process water, eliminating up to 98% of dissolved inorganic materials and more than 99% of dissolved organic materials, colloids and particles. Veolia’s Hydrex chemicals which optimises the performance of utilities and water treatment assets, complete the unit.
