A concise review on performance improvement of solar stills

Abstract

Conversion of saline water into freshwater by the use of solar thermal energy is known as solar desalination and the devices used for carrying out solar desalination are known as solar stills. The major problem faced by the solar stills is that they have low productivity and therefore unable to meet the high demand for freshwater. Over the years, several researchers have worked on improving the productivity of solar stills. Preheating of feed water, forced convection and energy storage are some of the methods used to increase their efficiencies. Some of these methods are discussed in the present review. The main aim of the current review is to provide the researchers with an idea to select the appropriate method for the improvement in the performance of currently available solar stills.

“…In the process, a passive solar power distillation system uses direct sunlight to evaporate dirty water in a storage tank, while an active solar power distillation system has several additional requirements that are used to increase heat transfer thereby speeding up evaporation. This can be done through some design modifications, integration of additional devices or a combination of both [6].…”

Energy, exergy, economic, exergoeconomic, exergoenvironment, and enviroeconomic (6E) analysis of solar stills—A critical review

“…According to the results of the investigation, this SS is 51%–148% more productive than a traditional SS and only circulated hot water enhanced the productivity by 56%. Narayanan et al 74 reviewed SS. The essential goal of this review is to guide researchers on how to select the best approach for improving the SS.…”

“…Hampir 75% permukaan bumi ditutupi oleh air dan hanya 0,014% air yang layak dikonsumsi manusia, dimana sebagian besar air yang ada berupa air laut payau yang tidak dapat dimanfaatkan secara langsung [1]. Kelangkaan air tawar bersih berada pada tahap kritis yang akan berdampak buruk pada sektor pertanian, industri dan yang terpenting bagi kelangsungan hidup dan pembangunan manusia [2]. Perkembangan dunia meningkatkan kebutuhan manusia juga meningkat, hal ini menyebabkan meningkatnya permintaan yang akan berdampak habisnya sumber daya air dan sumber daya lainnya [3].…”
