“…Expectedly, for most real distillation processes, an increase in hot feed temperature would lead to an increase in distillate production because more distillate would be produced when a higher quantity of pure water is evaporated from a feed source with significant heat content [1,26]. Meanwhile, a low cold distillate temperature would not necessarily enhance the removal of enough heat of condensation from the vapor, as this extraction depends on the driving force and efficiency of heat transfer, membrane characteristics, flow dynamics, polarization effects and number of stages in the system [33,35,37,38].…”

a b s t r a c tOrthogonal experimental design, correlation analysis and response surface charts were used to identify the parameters influencing the operational efficiency of direct contact membrane distillation (DCMD). The orthogonal array design method was used to optimize the number of experimental trials required for dependence analysis. The operating factors studied were hot feed properties (temperature, salinity, flowrate) and cold distillate characteristics (temperature, and flowrate). The impact of those factors on three DCMD performance indicators -cold distillate production rate, performance ratio and recovery ratio -was investigated. The most significant factors influencing each performance indicator were obtained from the quantitative values of main and interaction effects, and confirmed by using the Pearson product-moment correlation coefficients. The main effects of feed and distillate temperatures on the performance indicators were the greatest, indicating that the most significant factors were the feed and distillate temperatures. The maximum distillate production rate was obtained at feed and distillate temperatures of 90 and 15°C, respectively. The optimum recovery and performance ratios were obtained at a feed flowrate of 1.6 L/min but when feed temperature was kept at 70°C.

This article presents a theoretical study and experimental validation of a new solar bubbler basin using as a humidifier in humidification–dehumidification desalination system. The prototype consists mainly of a simple solar basin, filled with water, through which air is forced to travel upwards in form of bubbles. A detailed mass and heat transfer analysis was elaborated to model the dynamic behavior of the new humidifier. It is through a comparison with the experimental data that the validity of the proposed model was tested. The simulation results have revealed that the humidification efficiency and the amount of evaporated water can reach 98% and 6 kg m−2 day−1, during the spring equinox. The effects of some operational parameters (water depth, inlet air temperature, and flow rate) were investigated. It was found that the inlet air temperature and flow rate have a significant effect on the water content difference in the humidifier. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 518–526, 2019

“…However, due its high salinity, water from seas and oceans cannot be used directly. This is where desalination becomes the key factor of supplying water suitable for human use by converting the saline water to fresh water [2][3][4]. Additionally, according to the World Water Council, the world would be about 17% short of fresh water by 2020 [5].…”

Fossil fuels have been used as the main energy source for the desalination technologies. The continued increase in the demand for desalinated water has resulted in rising greenhouse gas emissions and threat to available fuel reserves. Consequently, most commercial desalination processes powered by fossil fuels have significantly contributed to environmental pollution. Renewable energy comes into the picture as an environmental friendly option as well as a means of fossil energy minimization. In this paper, a review on the use of renewable energy in recent desalination processes has been carried, with a focus on wind and geothermal energy.
