With the rapid rise of ro uf membrane in various fields, there are many ultrafiltration membrane material on the market, and the quality and main purposes of different raw materials are also different. Many consumers have a headache when choosing. The following introduces the production raw materials of ro uf membrane, and compares different materials and properties to choose uf membrane module that suits your needs.
1. Polyacrylonitrile (PAN) PAN is a kind of membrane material used in the early days. It is a hydrophilic material and easy to coat. The advantages are that the materials are easily available, the film production cost is low, the production process is simple, and the daily output is large. The disadvantages are low compressive strength, high ductility, and poor acid and alkali resistance.
5. Polypropylene (PP): The material is cheap, the whole process of environmental protection, low consumption, low cost, good acid and alkali resistance, resistance to organic solutions. It is usually manufactured by the stretching method to realize the microfiltration grade. The disadvantages are low filtration accuracy, easy to be polluted by the environment, backwash recovery, high tensile strength, and large total membrane area. Used for purified water filtration and wastewater treatment.
Generally speaking, the above-mentioned ro uf membrane materials have their advantages and disadvantages, as long as you select the corresponding ultrafiltration membrane 1 according to your needs, you can use it.
