Anti-fouling system for ship's saltwater circuit SANILEC®
Severn Trent De Nora
The purpose of on-site generation of a sodium hypochlorite solution from seawater is to economically and safely produce this powerful biocide and disinfecting agent in offshore applications. When injected into the cooling water circuits, on-site generated sodium hypochlorite solution provides efficient protection to the equipment against the growth of organic fouling (micro and macro). This occurs without the undesirable side effects of commercial hypochlorite (such as the build up of hard deposits by reaction of excess alkalinity with the substances dissolved in water) or the safety hazard connected with the transportation, storage and handling of chlorine gas. Because this technology eliminates dependency upon outside suppliers and the heavy costs of purchased commercial products, it finds application in a broad spectrum of offshore facilities requiring biofouling control of water systems.
