Ultrafiltration equipment

Nov 14, 2019

The ultrafiltration equipment uses the ultrafiltration membrane as the core product, and utilizes the intercepting ability of the porous material to remove a certain amount of impurity particles in the water by physical retention. Under pressure driving, substances such as water, organic low molecular weight and inorganic ions in the solution can reach the other side of the membrane through the micropores in the fiber wall, and the large size of the bacteria, colloids, particles, organic macromolecules, etc. in the solution. The material is trapped to achieve the purpose of sieving the different components of the solution.

The ultrafiltration device uses a pressure as a driving force to utilize a physical screening process in which the ultrafiltration membrane separates the liquid at different pore sizes. The molecular cut amount (CWCO) is generally from 6,000 to 500,000 and the pore diameter is 100 nm (nanometer). The membrane used for ultrafiltration is an asymmetric membrane, and the surface active separation layer has an average pore diameter of about 10 to 200, and can intercept macromolecules and colloidal particles having a molecular weight of 500 or more, and the operating pressure difference is 0.1-0.5 MPa.
