Desalination plants are responsible for removing salt from water sources, so that it becomes usable for human consumption. Reverse osmosis, multi-sage flash and Multi-effect distillation, are three main types of equipment and processes used that differentiate desalination plants. Thermal technologies such as MSF and MED are the most used in the Middle East, as they have low access to fresh water supply yet have access to excess energy.
