De Nora, a global water technology company, recently announced that it had won of one of the largest water disinfection projects in Asia at the Johor River Water Works, the largest water works in Malaysia.
This project will see De Nora’s ClorTec® 2250 product, an on-site hypochlorite generator, replacing the existing liquid chlorine and ammonia systems at Johor River Water Works. In total, De Nora will provide 11 units across all three plants on-site. Each unit will have an electrolyzer capacity of 1020kg/day, exceeding the tender requirements of 900kg/day.
This win is on the back of other successful projects with the leading water utility company in Singapore, where De Nora’s ClorTec systems have been installed at multiple locations, including Chestnut Avenue Waterworks in the west of Singapore.
De Nora’s on-site hypochlorite generation products use water, salt, and power to produce chlorine-based disinfectants by passing a solution of sodium chloride through an electrolytic cell and converting the chloride ions into sodium hypochlorite. It provides a safe, economical and effective solution for drinking water treatment without creating or transporting hazardous chemicals.
As part of the tender process for the Johor Water Works project, the ClorTec 2250 systems had to meet stringent performance and efficiency targets in Factory Acceptance Tests (FAT) across the relatively short period of six months.
The company’s systems are optimized to help to minimize production of by-products like chlorate, perchlorate and bromate. In tests performed at Chestnut Avenue Water Works, De Nora showed that on-site hypochlorite generation systems produced by-products such as chlorate and perchlorate at four to six times lower than the recommended value set out. These tests were certified and endorsed by the operation in charge at Chestnut Avenue Water Works.
“We are excited to provide the Johor River Water Works with a safe, economical and effective solution to generate hypochlorite on-site,” says Marwan Nesicolaci, General Manager, Asia Hub at De Nora Water Technologies. “This win is a testament to our ongoing commitment to deliver innovative solutions for water treatment across the region, and we look forward to our continued partnership with other partners across Asia Pacific.”
The company’s units at Johor River Water Works are expected to be operational by March 2023.
