Challenge
‘What’s Cooking?’ wanted to drastically reduce its water consumption and make reuse of process water possible within a sustainable and future-proof framework. The ambition: evolve towards a closed water loop and be less dependent on groundwater and mains water.
Approach
Chosen Water Treatment
Selected Technologies
Result
Smart reuse, maximum impact! With a reuse capacity of 30 m³ per hour, ‘What’s Cooking?’ is taking a significant step towards circular water management. The purified water, which reaches drinking-water quality, is reused for cleaning machines. The residual stream? Minimal and limited to salts and chlorides. The following water treatment techniques were used:
- Biological pre-treatment of effluent
- Triple glass filtration to capture residual biological fractions
- Closed Circuit Reverse Osmosis (CCRO) for maximum water recovery with minimal waste stream
- Chlorine dioxide injection for disinfection of reused water
- Sand filtration + upflow softening to top up with groundwater
- Water softening for mains water, only as an emergency solution
Thanks to a combination of biological pre-treatment, glass filtration, Closed Circuit Reverse Osmosis (CCRO) and a chlorine dioxide injection, a robust system is created with high yield and low impact. Topping up is done with groundwater or – only in emergencies – softened mains water. The entire installation is managed via a ‘water service model’ in which Eco-Vision is responsible for design, operation and maintenance. This ensures that ‘What’s Cooking?’ has sustainable water management without operational worries. A showcase of how technology and sustainability together make the difference.

Other cases
Bendec
Zero Liquid Discharge in aluminium treatment
For Bendec, Eco-Vision realised a mobile closed water circuit, reusing rinse water via ion exchangers and evaporating residual water with a vacuum evaporator on heat pump. Result: 11,000 m³ water savings, €22,000 annual savings and no more liquid discharge. 100% circular water management is now a reality.

Eurocircuits
Smart wastewater management in the PCB sector
Thanks to a combination of physico-chemical treatment and advanced ion exchangers, Eurocircuits reuses 60,000 m³ of water each year and reduces the copper content to below 0.05 ppm. Result: official authorisation to discharge to surface water and an annual saving of €110,000.

Datwyler
Closed water loop in the medical industry
At Datwyler, the rinse water from rubber components has been fully reused since 2018 via a reverse osmosis installation in closed loop. The result: 33,600 m³ less water consumption and €85,000 saving per year. Circular, pure and efficient.
