A review of clean and sustainable water production via curved desalinators: A super recent data

Abstract
Designing of solar energy – having the advantage of zero fuel cost – based enclosed water evaporators is typically related to some created standards. In this connection, there has been an on–going global push, where a lot of academics have joined the fever of beautifully constructing solar distillers. These latter, as a pragmatic choice to tangibly match the demand and fresh water sustainably supplied, are a tapestry of uniquely combining both such shapes and suitable materials. The current review aspires to investigating into the effect of, in particular, reforging the prismatic solar desalinator geometry to curved one (specifically tubular (or cylindrical), conical, oval, semi–cylindrical, spherical, and hemispherical (dome) stills). Being the former is facing some real issues, the previous one has emerged to somewhat solve them, such as solar radiation receiving, shadow creation during operation, and another next issue, sun–tracking. Furtherly, a comparison with the recent released reviews on the same subject in order to target the best configuration (s) employed for producing distillate in terms of quantity and quality (adhered to the World Health Organization rules). The analysis concludes that three potential solar still designs have topped the list of reviewed works, namely tubular, hemispherical, and active conical distillers. These systems demonstrated a great capability of generating distillate, higher efficiency, as well as minimized produced fresh water price; however, still there is another constraint of cost of additional solar collectors as pre–heaters, which render, for certain cases, the water cost challenging. • Super recent updates on curved shapes of solar stills were presented. • Examining the significance of design, TES addition, collectors’ coupling, and others. • The best configuration for generating distillate has been targeted.
