What is the method, principle and common choice of seawater desalination? Please, 3Q. The seawater desalination method, the seawater desalination in the modern sense, was developed after the Second World War.After the war, international capital vigorously developed oil in the Middle East,To make the region's economy develop rapidly,Rapid population growth,Demand for fresh water resources is growing in this otherwise arid region.The unique geographical location and climate conditions in the Middle East,With its abundant energy resources,In addition, seawater desalination has become a realistic choice to solve the shortage of freshwater resources in the region,And put forward the requirements of large-scale seawater desalination device.In this context,In early 1960s,Multi-stage flash desalination technology came into being,The modern seawater desalination industry has also entered an era of rapid development.The large-scale application of seawater desalination technology began in the arid Middle East,But not li
