The Kingdom of Saudi Arabia has great interest in the development of desalination technologies. Great efforts have been carried out in several projects that aim at developing water technologies such as osmotic membranes, porous membranes, and ultrafiltration membranes that are used in several water technologies related fields. Water technologies are divided into several types, such as water desalination, and each has many branches and divisions. Each technique is applied depending on the amount of water to be produced, to the energy needed for operation as well as water quality needed, and several other considerations. Water treatment technologies are considered important for the purpose of removing various contaminants that are harmful to humans, or to agricultural or industrial purposes. Water treatment technologies, on the other hand, are divided into several branches, depending on the required quality of water produced. For example, filtration technologies using organic and inorganic membranes are the most widely used technologies for removing particulates and organics with large molecular weights. Physical and chemical oxidation treatment technologies are also important and can be used for removing harmful chemical compounds in water. We aim at developing water treatment and desalination technologies, establishing a database for water treatment and desalination technologies, and developing efficient pilot plants, experimental rigs and technical products for water treatment and desalination. Aligned with water technologies, we aim to train and develop young leaders under the Technology Leaders Program which promotes scientific research for a brighter industrial future.
