Applications of reverse osmosis desalination membranes for afforestation

This paper aims to study the reverse osmosis membranes which can desalinate seawater. Mechanism of water seepage has been studied by XRD analysis, scanning electron microscope and other methods. Effects outside temperatures and soil moisture conditions on the water infiltration rate of the membrane are explored by comparison. The experimental results reveal that the water seepage through the dense membrane layer is porous to filter out small ions in order to achieve the role of desalination. And the higher the outside temperature, water seepage rate of the membrane increased; the lower the outside temperature, water infiltration rate decreases; the higher the soil moisture, water seepage rate of the membrane increases; the lower the soil moisture, water infiltration rate decreases. In this thesis, the main innovation is combining the reverse osmosis membranes and afforestation, and analyzed by comparison of experimental factors. The results of this investigation can be applied to the actual afforestation, according to the different conditions to make better use of the reverse osmosis membranes in the actual use.
