ADA’s innovative oxidant sensor technology monitors and controls biofilm formation in seawater cooling systems used in submarines, surface vessels, industrial processing plants, power plants and off-shore industrial facilities.
ADA’s oxidant sensor monitors the electrolytic halogenation of seawater, a process that uses electricity to convert natural bromide and chloride salts in seawater to the hypohalous acids hypobromite and hypochlorite. (Hypochlorite is the ingredient in household bleach that makes it an effective disinfectant.)
Although hypohalous acids effectively kill marine organisms that invade seawater cooling systems, they are harmful to the environment if released in large concentrations. ADA’s oxidant sensor accurately monitors hypohalous acid concentration, providing real-time feedback to ensure the levels fall within a narrow range that is effective, yet harmless when discharged to the surrounding environment. Prior to ADA’s R&D efforts, there was no reliable method of monitoring electrolytic halogenation.
