SEACLOR® seawater electrochlorination systems are the preferred solution for biofouling control in power plants, cooling towers, LNG terminals and desalination facilities. SEACLOR® systems use a simple and straightforward process, combining two common consumables – seawater and electricity. This proven process eliminates the purchase, handling and storage of hazardous chemicals. 

SEACLOR® systems include electrolytic cell assemblies of modular construction combined in an electrical and hydraulic series. Electrodes are coated with De Nora’s patented DSA® formulas for varying water temperatures and chloride concentrations. Standard SEACLOR® systems range in capacity starting at 480 kg/day to 21,600 kg/day (1058 lb/day to 47,620 lb/day) per train with higher capacities achieved by adding trains. 

SEACLOR® systems are designed and assembled for continuous and unattended operation requiring minimal monitoring. Typical transport and handling limitations have also been considered to minimize customer logistics.
