Which is better, MBR membrane or hollow fiber ultrafiltration membrane? This mainly depends on where you use it and what kind of water quality you use. It is best to choose MBR membrane to deal with waste permeate. If it is used for water pretreatment, it is best to choose hollow fiber ultrafiltration membrane. next small make up for you to introduce in detail mbr membrane and hollow fiber ultrafiltration membrane, take a look at it!
The traditional secondary sedimentation tank uses gravity to settle impurities. In this process, many other situations may occur, such as sludge floating expansion, foaming, etc. Membrane filtration is more thorough and wastewater treatment is more convenient. However, because they are all membranes, MBR membranes will also face the problem of membrane pollution.
Hollow fiber ultrafiltration membrane is a kind of ultrafiltration membrane. Ultrafiltration technology is more mature and advanced technology. The hollow fibers are divided into an outer diameter and an inner diameter. The hollow fiber walls are covered with micropores. The pore size is expressed by the molecular weight of the interceptable species.
The raw water flows under pressure outside the hollow fiber membrane or in the cavity, and the raw water flows under pressure outside the hollow fiber membrane or in the cavity, forming an external pressure type and an internal pressure type, respectively. Ultrafiltration is a dynamic filtration process, the retained material can be discharged together with the concentrated water, will not block the membrane surface, and can run continuously for a long time.
