Multistage Membrane Distillation System for Water Desalination

Water scarcity is a worldwide challenging problem which is increasing sharply with the industrial development and population expansion. More than one-third of population in the world lives in water-stressed areas. Many people do not have access to freshwater because of the low amount of renewable resources of freshwater. In addition, many current freshwater resources are contaminated with waste water comes from the industry, cultivation, and human beings. Nevertheless, there are many seawater resources in the earth. As a result, researchers have used different types of desalination processes to overcome this water scarcity problem. This work is discussing one of the promising techniques for water desalination and treatment which called membrane distillation (MD) process.
