PVC membrane is a membrane material with water purification function. It can effectively remove impurities and pollutants in water, including suspended solids, macromolecular organic matter and some ions, through physical screening and molecular screening, thereby improving water quality. Its screening ability depends on the size and shape of the membrane pores. Since the ultrafiltration membrane made of PVC has finer membrane pores, it can remove tiny particles and organic matter.
In addition, PVC membrane also has good chemical resistance and is not easily eroded by chemicals such as acids, alkalis, and salts, which makes it highly adaptable when treating water containing chemical substances. At the same time, the surface of the PVC membrane is smooth and does not easily adhere to dirt, so it is easy to clean and maintain, and can maintain high water filtration efficiency.
However, the PVC material itself may have an odor, which may affect the taste of the water filtered through it. In order to solve this problem, activated carbon is usually added behind the PVC film to absorb odor and enhance the taste. Activated carbon has strong adsorption capacity and can effectively absorb organic pollutants in water and remove heavy metals, residual chlorine, volatile organic compounds and other pollutants.
In general, PVC membranes have broad application prospects in the field of water purification. However, considering the odor problems it may bring, other materials or technologies may need to be used in actual applications to further optimize the water purification effect.
