| Summary: | The current world population is expected to increase to about 9 billion in the next fifty years,
which will increase the intake of fresh water significantly. Purified water for drinking purposes
has become problem especially in arid regions, and is considered, nowadays, one the most
significant international health issue. Billions of Dollars are currently spent worldwide on
different desalination technologies to produce fresh water from Brackish and Seawater in order
to meet the world’s population demand for drinking water. Demands for reducing the cost of the
desalination processes by reducing/ eliminating the input energy have recently become a trend
and significant topic for researches. Therefore, the need for decreasing or if possible eliminating
the dependency of desalination technologies on fossil fuel and oil and make them
environmentally friendly through integration with renewable energy sources has become
inevitable. In this paper, a critical review of different aspects relevant to desalination
technologies has been presented. The review includes demonstration and comparative study of
the most popular desalination technologies currently in use and the focus is on Membrane
desalination (MD). It also includes the advantages and feasibility of integration the desalination
technologies with solar energy or waste heat sources. Recent developments in cost of Seawater
and Brackish water desalination, types of membrane desalination, types of membrane, and
fouling of membrane have been considered. |
