Ultrafiltration membrane is a kind of microporous filtration membrane with consistent pore size specifications and a rated pore size range below 0.01 microns. Applying proper pressure on one side of the membrane can screen out solute molecules smaller than the pore size to separate particles with a molecular weight greater than 500 Daltons (atomic mass units) and a particle size greater than 10 nanometers.

Its application range is very wide, ranging from household water purifiers to modern industrial production, mainly used in separation, concentration, purification of biological products, pharmaceutical products and food industry; also used in blood treatment, wastewater treatment and ultrapure water preparation In the terminal processing device; even in environmental protection also has a great range of applications.

At present, the commonly used ultrafiltration membrane devices in the industry mainly include the following five types: plate and frame type, circular tube type, spiral wound type, hollow fiber type, capillary type. Various basic types of membranes have different applicability. Today we Let’s talk about the application of hollow fiber membrane nozzles in ultrafiltration membranes.

Hollow fiber ultrafiltration membranes are widely used in the water purification industry due to their advantages of high packing density, large effective membrane area, high pure water flux, simple operation and easy cleaning. However, the materials used to manufacture hollow fiber ultrafiltration membranes are mainly a part of polymer materials with good fiber-forming properties. The requirements for the film material are good film-forming properties, thermal stability, chemical stability, acid and alkali resistance, microbial erosion and oxidation resistance. And has good hydrophilicity to obtain high water flux and anti-pollution ability.
