What is the difference between MBR and immersion ultrafiltration membrane? Feb 28, 2018


The MBR is used for sewage treatment, soaking in sludge, and immersion ultrafiltration is only a form of ultrafiltration, and filtration is water without sludge.

Among them, the performance requirements of the two kinds of films are different. The MBR requires that the type of lining film can be relatively strong, and the pore diameter is low, and the general pore size is wide and the pore size is large, and the film can be clean.

However, the immersion ultrafiltration is relatively low in strength requirement, and the pore diameter is high, and the distribution is narrow and the hole is small. Even after filtering, the water can be used directly for RO.
