A corrosion and scale control chemistry for cooling water, in a study at a large gas plant, reduced phosphorous content in the cooling tower discharge by more than 80 percent while achieving the targeted mild steel corrosion rates. As a result, the plant will meet pending phosphorous discharge regulations and avoid capital costs of approximately $5 million for a phosphorus removal system.
E.C.O.Film, which stands for engineered carboxylate oxide, was developed by Suez. It 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. E.C.O.Film removes the risk of costly phosphate deposition and meets regulatory requirements in environmentally restricted and phosphorus-restricted applications.
