Most of our common geomembrane constructions can play their role with an overall water pool, but for chemical plants, this cannot meet their usage needs. It is like our tap water treatment plant. If impurities need to be removed from sewage, a filter pool is needed. After removing impurities, purifying sewage into grey water is another process, which also requires a filter pool. Then, the grey water is converted into drinkable water, which requires a water storage tank. Of course, the above is just an analogy. For chemical plants, it also needs to treat wastewater multiple times to meet emission standards, so we also need good supporting facilities.
The membrane material used this time is 2.0mm thick HDPE anti-seepage membrane, national standard type, and the geotextile used is 500g short-fiber geotextile. The welding method used is hot melt, and the connection method of the geotextile is seam. Party A conducted on-site sampling of the incoming samples and welding seams, and the inspection method was witness inspection.
The construction time is 90 days, with a total construction area of 30,000 square meters of geomembrane and 60,000 square meters of geotextile. There are 20 construction workers, and the entire construction of the site has been completed.
