Severn Trent De Nora will provide its SEACLOR® seawater electrochlorination system for biofouling control of key mechanical equipment at Phases 2A and 2B of the Keppel Merlimau Cogen 800-MW power plant in Singapore. The contract for the SEACLOR system was awarded by Alstom, the project’s general contractor.
Thermal power stations located along seacoasts typically use seawater as a coolant in the steam condensers. SEACLOR systems generate sodium hypochlorite onsite, and introduce the disinfectant to the power station’s seawater intake. The disinfectant works to prevent the fouling of the steam condensers and equipment such as seawater circulating pumps, bar screens and drum screens. By controlling biofouling, power generation efficiency can be significantly increased. According to Marwan Nesicolaci, vice president of international sales and business development for Severn Trent De Nora, “Severn Trent De Nora worked on Phase 1 of the plant and we’re pleased to supply our SEACLOR system for Phases 2A and 2B of this project.”
SEACLOR systems have demonstrated reliable, economic and low maintenance operation in controlling biofouling at power plants and at cooling towers, liquefied natural gas terminals and desalination facilities around the world. The systems range in capacity from 10 to 900 kg/h per train.
