The scarcity of drinkable water supplies is becoming a serious and troubling challenge to long-term development. This issue emphasises the urgency implementing rapid desalination options. However, capital-intensive process that requires significant amount energy, since it now mostly powered by fossil fuels across globe, has potential leave carbon footprint. In this light, transitioning green en...

Abstract Humidification–dehumidification desalination (HDH) is one of the suitable methods for saline and brackish water in a small scale. In this research, an HDH method with direct contact dehumidifier has been analyzed theoretically experimentally. The setup consists two similar packing towers humidification dehumidification, 10 inches diameter, which are filled up to 1 m Rushing packing. ne...

Water scarcity is a pressing global issue driving the need for efficient and sustainable water reuse desalination technologies. In last two decades, humidification–dehumidification (HDH) has emerged as promising method small-scale decentralized systems. This paper presents comprehensive review of recent scientific literature highlighting key advancements, challenges, potential future directions...

This paper applies irreversibility analysis to characterize humidification-dehumidification (HD) desalination cycles and to identify how to further improve cycles and components. It is shown that minimizing specific entropy generation of the cycle maximizes the gained output ratio (GOR). It is also shown that each cycle has one limiting component that cannot be substantially improved and a seco...

This article applies nonlinear programming techniques to optimize humidification-dehumidification (HD) desalination cycles for operating conditions that result in maximum gained output ratio (GOR). Closed air open water as well as open air open water cycles, each with either an air or a water heater, were considered in this analysis. Numerical optimization resulted in a substantial increase in ...
