The current research experimentally investigated a sustainable desalination method to maximize freshwater production at minimal costs. Solar photovoltaics are used as a source of clean and renewable energy. The system used in conducting the experiments consists of: an air heater, water heater, two stages of cross-flow humidification, two stages of cross-flow dehumidification, and an oxyhydrogen gas generator. The setup's working principle is the open-air and closed water cycle. A centrifugal fan blows the ambient air to pass through the air heater. Air is heated through a heat exchanger, which is consequently heated by hot water. Water is heated using a new heating approach by using a mixture of 20% natural gas and 80% hydrogen gas with less impact on environmental pollution. Air is then humidified through two-stage humidification systems using a high water temperature technique, then through the innovative vibrating plate circuit, respectively. The humidified air is condensed through two consecutive dehumidification heat exchangers. The system parameters are optimized to enhance freshwater productivity. The studied operative parameters are air mass flow rate, water mass ratio (WMR), and the effect of adding a second stage of humidification. The results showed that the maximum daily productivity is 49.3 kg/day. The optimum air mass flow rate and water mass ratio to obtain maximum productivity was found to be 0.375 kg/s and 0.6, respectively. Furthermore, the experiments' results showed that two-stage humidification enhanced freshwater productivity by 23.25% than that of the single stage of humidification. Finally, an economical study analysis conducted for the test rig showed the cost per liter to be 0.

Industrial wastewater contains high concentrations of inorganic salts and organic matter. This experiment studied a system for treating wastewater containing high concentrations of inorganic salts and organic matter. The setup consists of a closed-cycle humidification and dehumidification system and a filter press. Chemical wastewater was used as the treatment solution, and the treatment performance of the system was tested and analyzed. The system effectively reduced the chemical oxygen demand (COD), electric conductivity (EC), total nitrogen (TN), and ammonia nitrogen (NH4-N) in the wastewater and, at the same time, dehydrated sludge was obtained through a filter press. The system maintains a stable removal rate of each index (COD, EC, TN, and NH4-N) in wastewater and can remove inorganic salts and organic matter from wastewater. The system can successfully treat industrial wastewater containing high concentrations of inorganic salts and organic matter.
