Do you know the common types of MBR membranes?Time：2022-01-18 MBR membrane is the abbreviation for MBR membrane bioreactor, which is a new type of water treatment technology that combines aerated biofilter and membrane separation technology. At present, MBR membranes on the market are mainly divided into four types: ceramic membranes, tubular membranes, hollow fiber membranes, and flat membranes. Ceramic film has also been newly introduced in recent years, and together with organic chemical flat film, it is called "flat film". Ceramic film has good reliability in organic chemistry, and can withstand acid, alkali, solvent, and heat; The advantages of narrow diameters and efficient separation in higher education institutions. Organic tubular membranes, as a type of membrane component, are suitable for membrane separation equipment such as ultrafiltration membranes, microfiltration, and even nanofiltration. Their advantages include wide flow channels, high flowability of the feed solution in the tube, and low precision requirements for the preparation and treatment of the feed solution. The tubular membrane is easy to clean, and can be cleaned not only with chemicals, but also with mechanical equipment and physical cleaning methods. Hollow fiber MBR membrane and flat membrane are collectively referred to as "organic membrane", and the key material is PVDF (polyvinylidene fluoride), which is the key material for most membranes sold in the market today |
