“…Case (b) (heat inflow from one side of the channel, outflow from the opposite side) is found, for example, in the Memsys modules adopted in Vacuum Multi Effect Membrane Distillation (V-MEMD) [21], in which the generic stage is powered by the condensation heat from a previous stage, thus saving the thermal energy that otherwise should be provided from the outside. One side of each channel is provided with a microporous membrane allowing the passage of vapor, while the other side is a thin polypropylene sheet, on the outside of which the vapor from the previous stage condenses.…”

“…In its current state of development, since module production started in 2010, technical articles with trial results are currently unavailable. Pilot plants have been installed around the world, including in Singapore, Australia and India [140][141][142] . Current module capacity is specified at 50 m 3 /day [140].…”

Membrane distillation is a process that utilizes differences in vapor pressure to permeate water through a macro-porous membrane and reject other non-volatile constituents present in the influent water. This review considers the fundamental heat and mass transfer processes in membrane distillation, recent advances in membrane technology, module configurations, and the applications and economics of membrane distillation, and identifies areas that may lead to technological improvements in membrane distillation as well as the application characteristics required for commercial deployment.

“…The last point is important to compete with the many advantages of Reverse Osmosis (RO). In which, the Memsys V-MEMD unit, due to its modularity, it has wide range of applications, from small to large scale [7]. Figure 4a shows the photograph of the complete Memsys unit.…”

“…In general, the working principle of the Memsys unit is based on the Vacuum Multi-Effect Membrane Distillation (V-MEMD) process. According to the literature [7], the Memsys V-MEMD process has advantages due to some reasons, such as: internal heat recovery, high distillate flux, minimum heat loss, low specific heat transfer surface, low mechanical stress due to less pressure difference on membrane from feed stream and negative pressure, modularity. The last point is important to compete with the many advantages of Reverse Osmosis (RO).…”

Abstract. This research focused on the development of an innovative design of solar-powered desalination (SPD) system which was expected to solve the water and energy problem simultaneously. We have developed a portable and hybrid solar-powered desalination (SPD) system for producing potable water from saline water. It is a self-contained and integrated system which combines solar-thermal collector and solar-photovoltaic for its operation, and thus the system can operate to produce water by only using solar energy. Therefore, the system is highly suitable to be implemented in remote arid and coastal areas without infrastructures or connection to the grid (water and power), but blessed with abundant solar irradiation, like in Saudi Arabia. A Memsys Vacuum Multi-Effect Membrane Distillation (V-MEMD) unit was used as the core of the SPD system. A heat pump was also integrated into the SPD system for energy recovery and to improve the performance of the system. The system could be considered as sustainable and "green" desalination technology, which will be very useful for the Kingdom of Saudi Arabia. To study the performance of the system, small-scale tests have been carried out at the Engineering College -King Saud University, Saudi Arabia. Based on the experimental results, the system has run successfully by only utilizing solar energy.
