A method to prevent biofouling settlement in sea or brackish water intake and cooling water systems is necessary to help retain their efficiency and integrity. The most common method is continuous dosing with sodium hypochlorite, which is both expensive and environmentally undesirable. A pulsed chlorine dosing technique, Ecodosing™, has proved to be effective yet cheaper and less environmentally harmful in controlling biofouling at a refinery in the Botlek Rotterdam area in the Netherla

The UNIPER power plant, Maasvlakte (MPP3) is located adjacent to Rotterdam harbour on the North Sea coast and has a capacity of 1100 MW netto. The Power Plant utilises seawater for cooling of the condenser during the energy generating process. The seawater is extracted from the Europahaven and discharges the warmed seawater into an exhaust basin that flows out through the joint outlet (block dam) in the Princess Margriethaven. UNIPER uses bulk sodium hypochlorite to control biofouling and has

Project facts

Advanced Water Technology (AWT) build the Al Khafji Seawater Reverse Osmosis SWRO Desalination Plant, which is the world’s first large-scale solar-powered desalination plant. It is located in Al Khafji to the north-eastern part of Saudi Arabia near the Kuwait border.

The desalination plant was completed by late 2017. It will supply 60,000m³ of desalinated seawater a day to the city of Al Khafji in north-eastern Saudi

To maintain a reliable and efficient operation of seawater cooling systems, a biocide must be added to prevent settlement and growth of marine fouling species, both macro- and microfouling. Worldwide, the typical industry practice in coastal areas includes continuous chlorination of the seawater with periodic shock dosing. However, this practice is not based on ecotoxicological data of targeted species, but is generally based on a post-hoc observation of antifouling efficiency or performed as
