WP 6: Environmental Impacts Impacts of Conventional Desalination • Seawater intake for desalination and for the cooling system may cause impingement and entrainment of organisms, • airborne emissions of pollutants and carbon dioxide are caused by the generation of electricity and heat required to power the desalination plants, • chemical additives and biocides used to avoid fouling, foaming, corrosion and scaling of the desalination plants may finally appear in the brine, • discharge of hot brine with high salt concentration to the sea may affect local species.
