“…The United Nations estimates that by 2025, about 1,800 million people worldwide will face severe water shortages (Amirfakhraei et al 2021a). To relieve serious shortages of potable water supplies, water desalination methods and relevant devices have become attractive (He et al 2018;Amirfakhraei et al 2021b). Existing desalination plants are mostly large-scale.…”

Humidification–dehumidification desalination (HDH) is one of the suitable methods for desalination of saline and brackish water in a small scale. In this research, a HDH desalination method with a direct contact dehumidifier has been analyzed theoretically and experimentally. The setup consists of two similar packing towers for humidification and dehumidification, 10 inches in diameter, which are filled up to 1 m with Rushing packing. In this new HDH configuration, seawater and freshwater recirculation has been used in humidifier and dehumidifier sections, respectively. A steady-state mathematical model based on the mass and energy equations for each system component is presented. The effect of various input parameters on the freshwater production, gain output ratio (GOR) and specific energy consumption has been investigated. The results revealed that the inlet seawater and air temperature to the humidification tower had the highest and the lowest effect on the produced freshwater, respectively. Also, the maximum value of the GOR is 3.3, which is obtained in the equilibrium condition of the dehumidifier. The experiments show that the freshwater production of the proposed HDH device is 300 L/day, which can provide water for domestic consumption of a small family.

“…Olkis et al [17] analyzed the feasibility of a solar-powered ADS at two distinct European locations using advanced ionogel materials with regeneration temperatures as low as 25 • C. 1 m 3 /ton/day required 140 kg of ionogel and 200 m 2 area of solar collectors. Amirfakhraei et al [18] presented an advanced mass and heat recovery design for the ADS. During this recovery cycle, a heat exchange directly occurred between the adsorption beds and evaporator, resulting in an improvement in SDWP by 31%.…”

In this paper, improving the overall heat transfer coefficient by adding aluminum species to silica gel has been studied theoretically. An adsorption desalination system is proposed, and a lumped theoretical model conducted to investigate employing the metal additives within the adsorbent bed with and without a heat recovery between condenser and evaporator. A 30% of the total mass of the adsorbent bed contents was considered to be replaced by aluminum species. According to this, the overall heat transfer coefficient has been increased by 260%, which shows a good impact on the performance of the adsorption system. Daily water productivity was increased by 70% at the worst-case, reaching up to 17 m3/day/ton of silica gel without heat recovery. By employing heat recovery with the metal filing, the daily water productivity reached 42 m3/day/ton of silica gel which is four times the productivity of the classic silica gel-based adsorption desalination system.
