“…Gorjian also supports that this method should be applied in regions where the demand does not exceed 200 cubic meters per day [17]. The results obtained on the size of the desalination plant emphasize that large amounts of land are required.…”

Water is essential for the hotel industry, its disposition is key to ensure the viability of the tourism sector that grows disproportionately day by day plus the scarcity of water in the world, this situation forces hotels to find alternatives to meet the demand for water. One of the preferred alternatives is solar water desalination. The purpose of this paper is to demonstrate through this first literature review whether solar desalination is a viable technique to meet the demand of potable water in a medium-sized hotel in a coastal area. We conducted a review of the literature published between 1987 and 2018, the subject of which is solar HDH desalination. Inclusion and exclusion criteria were formulated and applied to determine the most relevant studies to achieve the purpose of this research. The review found that solar desalination can be feasible to apply in hotels if they have large amounts of land for installation or the demand for water is not large. However, there are more economic methods to desalinate water while at the same time producing more water with similar sizes of facilities. Such results have practical implication for the use of the systems of hotels in general.

“…The humid air must then be dehumidified by being brought into contact with a cold surface.In the first major 20 variation of the HD process,condensation occurs in a heat exchanger used to preheat the 21 seawater. In the second variation (dewvaporation), evaporation and condensation take place in 22 the same vessel [54].Humidification-dehumidification desalination requires a large amount of 23 thermal energy (300 to 550 kWh/m 3 ) but may be a viable process when a waste heat source or renewable energy source is available [39]. In HD processes, filtration and softening are required to prevent equipment fouling.…”

Assessment of desalination technologies for treatment of a highly saline brine from a potential CO2 storage site

et al. 2017

Brine extraction is a promising strategy for the management of increased reservoir 2 pressure, resulting from carbon dioxide (CO 2) injection in deep saline reservoirs. The extracted brines usually have high concentrations of total dissolved solids (TDS) and various contaminants, and require proper disposal or treatment. In this article, first by conducting a critical review, we evaluate the applicability, limits, and advantages or challenges of various commerciallyavailable and emerging desalination technologies that can potentially be employed to treat the highly saline brine (with TDS values greater than 70,000 ppm) and those that are applicable to a ~200,000 ppm TDS brine extracted from the Mt. Simon Sandstone, a potential CO 2 storage site in Illinois, USA. Based on the side-by-side comparison of technologies, evaporators are selected as the most suitable existing technology for treating Mt. Simon Brine. Process simulations are then conducted for a conceptual design for desalination of 454 m 3 /h (2,000 gpm)pretreated brinefor near-zero liquid discharge by multi-effect evaporators. The thermal energy demandis estimated at 246 kWh per m 3 of recovered water, of which 212 kWh/m 3 is required for multiple-effect evaporation and the remainder for salt drying. The process also requires additional electrical power of ~ 2kWh/m 3 .

“…In addition, the condensation rate was found to increase with lower cooling water temperatures. While the aforementioned parameters were set to their optimal levels, it was also found that the forced convection method had a higher yield of fresh water in comparison to the natural convection, A recent humidification dehumidification desalination technology known as humidification compression was presented by Ghalavand et al [22]. The main characteristic of this technology is the polytropic compressor where no heater is required.…”
