De Nora, a company specialized in sustainable electrochemical solutions, has developed CECHLO™ – MS, a 12.5% sodium hypochlorite generator system that also produces chlorine gas (Cl₂) and sodium hydroxide (NaOH) directly at the point of use. This technology is designed to improve safety, efficiency and sustainability in the treatment of drinking water, wastewater and industrial processes.
How does CECHLO™ – MS work?
The system operates from common brine by means of an electrolysis process with a patented ion exchange membrane. This process converts salt water into chlorine and caustic soda, which are combined in a hyporheater to form high concentration (12.5%) sodium hypochlorite.
The modular plug-and-play design and skid-mounted system allow for quick installation, integration with existing systems and reduced maintenance. In addition, it incorporates De Nora’s exclusive DSA® electrodes, which improve performance and extend the life of the system.
Operational and environmental benefits
The use of CECHLO™ – MS has distinct advantages over conventional methods:
- Improved safety: no transport of liquid chlorine and no storage of hazardous substances.
- Reduction of disinfectant by-products (DBP) and assured regulatory compliance.
- Minimized operating costs, thanks to low salt and energy consumption.
- Greater hypochlorite stability, with less degradation of active chlorine.
- Sustainability: avoids transportation emissions and reduces the need for disposable packaging or hazardous waste.
- Adaptability: can operate as a centralized or decentralized unit and supply multiple plants.
CECHLO™ – MS 200: expanding into new markets
Following its implementation in large-scale projects in Hong Kong, Korea and Japan, De Nora has launched the regional version of CECHLO™ – MS 200 in North America, which responds to the demand for resilient solutions in the face of chemical market volatility, strengthening local support for municipalities and industrial operators.
The localization strategy seeks to streamline supply and facilitate technology adoption in countries where bulk chlorine infrastructure represents a logistical or financial risk.
A scalable and future-ready solution
CECHLO™ – MS represents a strategic evolution in water disinfection by offering a flexible, scalable solution aligned with global sustainability goals. Its implementation allows public and private operators to reduce costs, improve safety and gain independence from the chemical market.
