- Abstract:
- Humidification and dehumidification desalination process is a kind of water treatment technology which uses low-level heat energy to realize brackish water desalination. This technology improves the heat recovery and utilization rate of the equipment. The equipment can separate the humidification box from the dehumidification box, so that the seawater and fresh water can be strictly separated. The brackish water can be limited in a small area, and other structure can be made of economic materials, thus reducing the equipment cost. In this paper, the principle, structure and research progress of brackish water humidification and dehumidification desalination technology are introduced. The main factors affecting the efficiency of brackish water desalination and related improvement were analyzed. The technical characteristics of the process were summarized in details, and the technical problems to be solved in humidification and dehumidification desalination technology were discussed. It is considered that the humidification and dehumidification technology with solar energy as the heat source is suitable for the arid and semi-arid areas with large reserves of brackish water and abundant solar energy, which is an effective measure to solve the problem of increasing drinking water for people’s livelihood.
