The Skikda desalination plant in Algeria has been in operation since 2009 with a capacity to desalinate 100,000 cubic meters of sea water per day through reverse osmosis. It supplies drinking water to the over 600,000 people in the city of Skikda and surrounding areas. The plant uses an intake tower, physicochemical pretreatment, double filtration stages, and five reverse osmosis membrane sets to treat the water. This desalination plant is part of Algeria's national program launched in 2005 to desalinate 1 million cubic meters of water per day to address the country's water scarcity issues.
