Your challenges
Patented drinking water treatment process

Increasing micropollutants in raw water
Water resources are increasingly contaminated by residues from agriculture, industry, and households (pesticides, pharmaceuticals, solvents…). Though concentrations are low, the variety of molecules creates a "cocktail effect" with potential health risks. Our technology CARBOPLUS® eliminates them.
Health safety and regulatory standards
Drinking water regulations are increasingly stringent, especially regarding pesticides and treatment by-products. Clean water must be guaranteed without converting pollutants into toxic residues. This calls for a safe, proven, and reliable process.
Integration into existing plants
Many treatment plants need upgrading to meet new standards without building new infrastructure. Our technology integrates easily within compact facilities and also allows future expansion.
Operating cost control
Energy efficiency and reduced chemical consumption are crucial. Our technology is simple, automated, and low-maintenance. A cost-effective and reliable solution essential for public utilities.
How does it work ?
CarboPlus® eliminates micropollutants through adsorption on suspended activated carbon within an upflow reactor.
A large carbon mass, continuously renewed, provides extended contact time for high and consistent treatment efficiency.
The resulting water meets the most stringent health and safety standards, ensuring reliable, long-term performance.

Reliable and effective
CarboPlus® removes a wide range of micropollutants: pesticides, pharmaceuticals, chlorinated solvents… It acts without chemical transformation, permanently removing unwanted molecules. Its performance is consistent over time.
Compact and integrable
Its small footprint allows easy integration in both new and retrofitted plants. It fits spatial constraints, including in protected areas. CarboPlus® is already implemented in many sensitive environmental zones.
Cost-effective
The process uses little energy and no chemicals. It operates with a wide range of activated carbons, tailored to local needs. It is a long-term technology anticipating regulatory developments.
Easy to operate
With no electromechanical parts inside the reactor, separation occurs by gravity. The system is automated and requires little maintenance. It easily adapts to seasonal variations in raw water quality.
