SUEZ has announced that it has developed a new corrosion and scale control chemistry for cooling water.
E.C.O.Film, which stands for Engineered Carboxylate Oxide, relies on the company’s proprietary engineered film technology to eliminate the need for phosphorus, and other anti-corrosion solutions that employ EPA priority pollutant metals. With wide applicability across cooling systems, E.C.O.Film is a socially responsible product that removes the risk of costly phosphate deposition, and meets regulatory requirements in environmentally restricted and phosphorus restricted applications. In a pilot study, the product helped a large gas plant reduce phosphate discharges by more than 80%, enabling them to comply with new regulations while avoiding the need for a US$5 million capital equipment expenditure.
“E.C.O.Film is a complete cooling water treatment solution that uses no phosphate and requires no metal additives,” said Hoshang Subawalla, Executive Vice President of Chemical & Monitoring Solutions for SUEZ – Water Technologies & Solutions. “It’s the perfect solution for systems with calcium phosphate deposition challenges, those facing tightened environmental restrictions, and customers that want to meet sustainability goals.”
Since the 1970s, phosphorus-based corrosion inhibitor programmes have provided a cost-effective method of protecting industrial assets such as cooling towers, chillers, and heat exchangers. When discharged into natural water bodies however, the phosphorus contributes to eutrophication and algae blooms due to the increased nutrient pollution.
SUEZ claims that its proprietary E.C.O.Film technology can eliminate deposition issues related to calcium phosphate, zinc phosphate, and other phosphate salts. It can help customers improve operational efficiency and increase time between cleanings and turnarounds.
