Reverse osmosis requires low salt content of the treated water source, but consumes a large amount of electrical energy. The membrane distillation has low water yield due to the problems of overlarge energy consumption, poor hydrophobicity of separation membranes and the like, so that the large-scale industrial application of the membrane distillation technology is limited.
The illumination time in the south ARUM is long, and the solar energy resources are rich, so that the device is suitable for desalting the saline-alkali water by adopting a photo-thermal method, but the traditional photo-thermal method has lower desalting efficiency, and therefore, an efficient, environment-friendly and sustainable saline-alkali water desalting device is needed.
