“…Bench-and pilot-scale studies have been undertaken on solar MD [43,130,137,159,[161][162][163][164][165][166]; however, they are still few compared to studies with the more mature technology of solar PV-driven RO and solar distillation. A solar MD system was tested to recover water and reduce brine volumes from RO concentrates by Dow et al [75].…”

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.

A B S T R A C TFresh water and electricity production in desert areas via the use of solar radiation represent examples of sustainability. The concentration of solar power by means of parabolic trough (PT-CSP) technology has a great potential not yet exploited in the realm of renewable energy production. A new technology for the solar energy section is being proposed by the authors which uses air as a working fluid. The use of air allows the cycle to be coupled with an inter-cooled compression section and a re-heated expansion section which is called Discrete Ericsson Cycle, (DEC-based plant). The paper presents an integration of such a CSP-DEC plant with desalination: where freshwater is produced according to a Low Temperature Multi Effect Distillation (LT-MED) technology. The LT-MED plant operates on the heat from the air coolers in the inter-stage cooling of the DEC-based plant. This heat is normally expelled to atmosphere. In fact, the heated air has the same temperature ranges required for the operation of the LT-MED desalination technology. This provides an efficient integration of energy for desert applications. The most important feature of this new solar energy plant is that the thermal needs of desalination in DEC-based plants do not interfere with the electricity production of the plant as is the case for current conventional PT-CSP plants which use diathermic oils as Heat Transfer Fluid (HTF). When the performance of the CSP DEC-based plants, integrated with the LT-MED technology, are compared to conventional CSP plants, they show an increased efficiency in terms of fresh water production per unit of energy produced. Thus, fresh water production can be considered as a valuable addition to the plant.

“…Normally in Carbon black industries, Solar power and desalination plant (Palenzuela et al, 2011) solar fields combined with thermal storage system power plant and Reverse osmosis (RO) (Attia, 2012;Antipova et al, 2013;Manolakos et al, 2009;Pérez-González et al, 2012;França et al, 2000;Song et al, 2002;Tan et al, 2012) desalination plant. Solar energy is received through solar field collectors (Nixon et al, 2010) in the form of heat and transferred to Heat transfer fluids (Esen, 2000;López-González et al, 2013) (HTF) by means of heat conduction.…”
