The lack of pure water and electricity in remote regions pushes to simulate of an innovative high-productive hybrid desalination system with the lowest power consumption rates, and this represents a major challenge recently. To achieve this goal, the present study aimed to simulate an innovative hybrid HDH-RO desalination system powered by photovoltaic-thermal modules and a solar dish concentrator. The proposed innovative hybrid system is characterized by integrating two common technologies for pure water production namely: HDH desalination unit and RO desalination unit with an energy recovery device. In order to achieve the highest production rates of pure water with the lowest possible rates of power consumption, the proposed innovative hybrid system was provided with photovoltaic-thermal modules and solar dish concentrators, as preheating units to heat the feed water before its entering the HDH-RO desalination unit. The photovoltaic-thermal modules have a dual function: enhancing the performance of photoelectric conversion, and simultaneously preheating the feed water before it enters the spiral coil of the solar dish concentrator. The solar dish concentrator with a solar thermal receiver was purposed to raise the feed water temperatures before it enters the HDH-RO desalination unit, to improve evaporation rates within the HDH unit as well as increase the rates of water permeating for the RO unit. The results indicated that the utilization of the photovoltaic-thermal modules and solar dish concentrators, as preheating units to heat the feed water before its entering the HDH-RO desalination unit has positive effects in terms of increasing the pure water productivity and reducing the rates of power consumption. The productivity of pure water for the innovative hybrid system ranged between 793 and 861 kg/h, with an improvement of 25.

“…It can operate at low temperatures and use any low-grade waste heat for powering the system. It is cost effective, can adopt local materials for construction, and can be possibly integrated with sustainable energy resources, such as solar and biomass [5,6]. In addition, one of the main advantages of this technology is the use of separate humidification and dehumidification components for the thermal desalination process.…”

Humidification-Dehumidification Desalination System Powered by Simultaneous Air-Water Solar Heater

et al. 2021

A humidification–dehumidification (HDH) desalination system requires thermal energy to desalt seawater. An environmentally friendly approach to obtain thermal energy is to utilize solar energy using solar collectors. Either seawater or air (or both) are typically preheated by HDH desalination systems before these fluids are conveyed to the humidifier column. Compared with preheating only air or water, preheating both is preferred because improved performance and higher productivity are achieved. Many researchers have proposed dual preheated HDH systems utilizing two separate solar heaters/collectors for simultaneous air–seawater preheating. In this study, dual-fluid preheating is achieved using a single solar collector. The proposed simultaneous air–water solar heater (SAWSH) is a modified flat-plate collector designed for simultaneously preheating air and seawater before the fluids reach the humidifier. A thermodynamic study was conducted using formulated mathematical models based on energy and mass conservation principles. Then, the dual-fluid heating HDH system is compared with HDH systems in which only air or only water is heated. This work found that the former outperformed the latter. The daily and monthly performance levels of the system in terms of the outlet temperatures of air and water, distillate rate, and gain output ratio were calculated using the weather data of the hot and humid climate of Jeddah City, Saudi Arabia.

“…The device which was used to manage this process is called the SS and the principle of its work depends on the famous physical evaporation-condensation concept (Ghodbane et al 2021). The comprehensive details about the characterization and types of the SS was reviewed by Kabeel and El-Agouz 2011, Chauhan et al 2021, Alnaimat et al 2021and Jobrane et al 2021. The conventional single or double slope SS produced low productivity due to shadow effect occurs by the basin walls.…”

The present work deals with the experimental investigation of Hemispherical Solar Still (HSS) using different basin materials with and without Internal Reflector (IR). Three solar stills such us HSS with Steel Basin (HSS-SB), HSS with Zinc Basin (HSS-ZB), HSS with Copper Basin (HSS-CB) was fabricated. Experiments was conducted with and without IR. It was found that, the productivity of the HSS-CB (4.99 kg/m2/day) was better than HSS-ZB (4.26 kg/m2/day) and both of them were better than HSS-SB (3.64 kg/m2/day). Also, It was found that the productivity of the HSS-CB&IR (5.67 kg/m2/day) was better than HSS-ZB&IR (5.04 kg/m2/day), and both of them were better than the HSS-SB&IR (4.28 kg/m2/day). The results revealed that use of IR improves the yield of HSS from 12 to 15.6%. Also thermal and exergy efficiency of the HSS was improved by 14.4 to 20% and 21.1 to 25.4% using IR than the without IR. Furthermore, recovery period and water quality analysis has been carried out. The recovery period of HSS-SB, HSS-ZB, HSS-CB, HSS-SB&IR, HSS-ZB&IR and HSS-CB&IR are 43, 38, 33, 36, 32 and 29 days, respectively.
