“…Therefore, the still productivity is greatly improved. On the other hand, similar results can be obtained if the still is integrated with a hot water storage tank [65], a mini solar pond [66,67], a heat exchanger [68,69], a heat pipe [70], an evacuated tube collector [71,72], solar air heater [73], photovoltaic-thermal (PV/T) modules [5,74], solar chimneys [75], cooling tower [76,77], and solar water heater [78,79]. Figure 15 illustrates some photos related to various types of hybrid solar stills [Gajendra et al [80], Omara et al [81], Siddiqui et al [82], and Panchal and Pravin [83].…”

This up-to-date and comprehensive literature study provides a rich overview of recent developments in several solar still types. This review examines a large number of theoretical, experimental, and computational studies connected to the single-slope, double-slope, solar still with a condenser, hybrid, and other limited types of solar stills. To make the work more relevant to readers, the authors provide a panoramic view of solar still varieties as well as a complete overview of the most recently published review papers in the solar stills field. The most important conclusions drawn from prior research are carefully discussed and outlined in a useful table to give interested researchers a good road map of many various sorts of solar stills and encourage them to pursue new research avenues in this field. The foremost key results of the evaluated work are presented in a table for readers’ convenience. The results indicated that the absorption in the basin was improved by adding charcoal, matt, sponge, jute and cotton clothes, dye, wick, porous or energy-storing material, black rubber, and floating absorber sheet. Moreover, the productivity of solar stills was significantly improved by using the inclined external flat-plate reflector, combined stills, condenser, sun tracking system, reflectors, greenhouse, hot water tank, solar collector, heat exchanger, and solar pond. Further, heat loss was minimized by re-utilizing the latent heat of condensation, cover cooling, and increasing the insulation thickness.

Life without water is not possible on the earth while modern humans need water not only for drinking, sanitization, and agriculture but also for industry, thermoelectric, and cooling plants. Hence, emphasis on water sustainability through different sectors including thermoelectric and cooling plants is an intelligent strategy while the tight connections of water and energy guide study towards energy-water nexus investigations. Cooling towers are equipment for dissipating the excess heat by water evaporation or they hidden gates for wasting water. The objective of the present study is to elaborate on the role of cooling towers, categorizing various methods for modifying water and energy consumptions through past studies, and mapping future studies regarding cooling towers. Presenting a history of energy-water modeling methods of cooling towers, the Markel, the Poppe, and the effectiveness–(NTU) models, has followed by assessing the environmental impact of cooling towers in the form of excess water consumption, plume, and energy usage. Summarizing and organizing the past efforts for upgrading water management in cooling towers have been in two directions either providing more water supply, or modifications of the cooling tower to use less water. Then the different methodologies for each direction are introduced for further elaborations. The practical outcome of this study is proposing the practical methods of improving water sustainability for any cooling towers from past studies to assist engineers in the industry for quick modifications of cooling towers. Showing the roadmap for the planning future investigations on the cooling towers based on the past efforts is another outcome of the present study to provide an insight for academia with research interest on cooling towers.

“…Several techniques have been developed to increase the productivity of solar stills with various designs, including the use of primary solar heating in different ways to increase the evaporation rate [43,44]. The use of internal and external reflectors to reflect solar rays increases the heating of the absorption basin [45,46], and the use of fins in the absorption tank increases the heat exchange process between the absorption tank and water [47][48][49]. Different types of fillings can accelerate the evaporation process [50,51], and nanomaterials can be used to improve thermal performance [52][53][54].…”

Pyramidal Solar Stills via Hollow Cylindrical Perforated Fins, Inclined Rectangular Perforated Fins, and Nanocomposites: An Experimental Investigation

et al. 2022

A practical study was conducted to improve the performance of conventional pyramidal solar stills (CPSS) using two types of fins with differing geometries, as well as nanocomposites of TiO2 and graphene. The first fin was hollow, cylindrical, and perforated (HCPF), whereas the second fin was an inclined perforated rectangular fin (IPRF). The fins were integrated with the base of a solar still to evaluate their performance in comparison with a CPSS. The obtained experimental results demonstrated that the pyramidal solar still with hollow perforated cylindrical fins (PSS-HCPF) and the pyramidal solar still with inclined perforated rectangular fins (PSS-IPRF) produced more distillate than the PSS-HCPF and CPSS under all examined conditions. The daily productivities of the CPSS, PSS-HCPF, and PSS-IPRF were 3718, 4840, and 5750 mL/m2, respectively, with the PSS-HCPF and PSS-IPRF improving the productivity by 31.3% and 55.9%, respectively, compared to that of the CPSS. In addition, using nanocomposites with PSS-IPRF improved the daily distillate production by 82.1%.
