Water desalination by brine recirculation using solar energy

Scientists have studied how solar energy can be used to power multi-stage brine recirculation desalination plants (MSF-BR or multistage flashing-brine recirculation) to supply drinking water to the city of Aqaba in Jordan.

MSF plants have a high energy consumption compared to other desalination technologies and, at the same time, they can be powered by renewable energy with a high production quality. These plants produce around 26% of all desalinated water in the world and, if coupled with BR and solar energy, could be cheaper than reverse osmosis (RO) if the salinity is above 10,000 ppm, according to the scientists.

An MSF installation mainly consists of a multi-flash evaporator, which includes a heat recovery section and a heat rejection section, in order to reduce the system's excess energy.

This type of evaporator is generally used to produce fresh water from seawater, well water or industrial water.
