[0002] Recycling water is an important means of saving water resources. Geotextiles are needed to filter the recycled water to achieve the purpose of purification. Geotextiles are permeable geosynthetics made of synthetic fibers through needle punching or weaving. They are widely used in geotechnical projects such as water conservancy, electricity, mines, roads and railways. Therefore, geotextiles need to be permeable for filtration and drainage, so they must have good permeability. Geotextile permeability meter can be used to detect the permeability of geotextiles. It is one of the important instruments for monitoring whether the permeability quality of geotextiles is qualified or not.
