The potential of solar-driven humidification-dehumidification desalination for small-scale decentralized water production
World-wide water scarcity, especially in the developing world, indicates a pressing need to develop inexpensive, decentralized small-scale desalination technologies which use renewable resources of energy. This paper provides a comprehensive review of the stateof-the-art in one of the most promising of these technologies, solar-driven humidification-dehumidification (HDH) desalination. Previous...

متن کاملExperimental Validation for Two Stages Humidification- Dehumidification (hdh) Water Desalination Unit
This paper demonstrates the preliminary experiments for two stage water desalination by humidification-dehumidification HDH process. An experimental set-up consists of two stages of closed air humidification dehumidification units. In this design, the saline water was heated by evacuated tube solar water heater integrated with electrically heated tank. A series of tests were performed in outdoo...

متن کاملSimulation of Hdh Desalination System Using Tilted, Two-pass Solar Air Heater
The present work represents a theoretical investigation of the performance of a solar air-heated desalination system using humidification-dehumidification (HDH) technique based on closed-water, open-air cycle under the geographical conditions of Dhahran (26.5°N, 50.2°E), Saudi Arabia. The HDH desalination system is suitable for small-scale decentralized fresh water production. It essentially co...
