De Nora launches Cechlo-MS 200 OSCG system

New design ensures reliable treatment, while minimising safety concerns and enabling supply chain independence for water operators

De Nora has launched the Cechlo-MS 200, an on-site chlorine generation system aimed at addressing water and sewage treatment challenges. The Cechlo-MS 200 system utilises ion exchange membrane electrolysis (IEM) technology to turn salt, water and electricity into a chlorine-based solution ensuring on-demand supply of chlorine on site, improving safety, mitigating concerns on storage, securing availability and minimising lifecycle cost.

Marwan Nesicolaci, general manager, Asia hub of De Nora Water Technologies, commented: “The Cechlo-MS 200 is the latest generator in the De Nora Cechlo-MS systems product family. Unlike other solutions available in the market, the Cechlo-MS 200 system offers advantages thanks to its optimised and standardised design – customers benefit from simple and quick installation, easy operation and maintenance and a faster turnaround on projects. Cechlo technology gives our customers the flexibility to choose from on-site generation of chlorine gas or hypochlorite solution, which are both proven effective and economical for water disinfection applications.”

Responding to modern water and sewage treatment challenges
In an environment with ever tightening regulations, water and sewage treatment plans have been increasingly challenged to build treatment processes and plants that offer regulatory compliance, self-sustainability, safe operation, value economics and environmental-friendly solutions.

Cechlo-MS on-site chlorine generation system was developed based on De Nora’s expertise in electrochemistry combined a deep experience of complex water treatment applications. The system allows plant operators to build a self-sustainable and reliable supply chain of chlorine, eliminating the safety risks associated with having delivered and storing large amounts of chlorines, especially in populated areas. It also allows plants to optimise operation cost and improve sustainability to address the modern-day challenges.

Many centralised water treatment plants today have either installed or are considering the adoption of this solution to address their needs, while meeting increasingly strict country safety regulations.

New and improved Cechlo-MS 200
De Nora Cechlo-MS 200 system generates on-site high strength sodium hypochlorite at 12% and chlorine gas in a plug-and-play configuration that produces chlorine on site. At the heart of the Cechlo-MS 200 system is the IEM electrolyzer, which has been continuously optimised through innovative upgrades, powered by De Nora DSA electrodes.

“Modern-day challenges of water treatment are becoming more complex globally, and there is increasing demand to rise to these challenges with technology,” said Nesicolaci. “The new De Nora Cechlo-MS 200 system utilises our technologies to help our customers to achieve a balance of safety, reliability, cost efficiency, and sustainability in water treatment. The team at De Nora continues to deliver innovative solutions that support safe and cost-effective water access for businesses and individuals, and we look forward to our continued working partnerships with water providers globally.”

This new product launch continues De Nora successes and partnerships in the region. It comes on the back of ground-breaking and solutions integrating both its Cechlo-MS on-site generation system and Capital Controls safe gas feed system to produce and feed chlorine gas and hypochlorite. This hybrid solution was implemented by Hong Kong’s Water Supplies Department (WSD), where De Nora delivered to several water treatment locations, with a combined design capacity of 8.46 tonnes/day chlorine.

This solution is a response to safety concerns around the transportation and storage of large amounts of liquid chlorine containers in waterworks located in highly populated areas, and for these waterworks to include self-sustainable water treatment designs. All systems are scheduled to be operational across the water treatment plants by 2022.
