Advantages of nanofiltration membranes

Nanofiltration is a relatively new membrane process that is commonly used with waters with low total dissolved solids (such as surface water and fresh groundwater) to soften (remove multivalent cations) and remove disinfection by-product precursors, Such as natural organic matter and synthetic organic matter.

Causes and Operation Analysis of Nanofiltration Membrane Pollution

Microorganisms include bacteria, algae, fungi and viruses. Adverse consequences: First, the mass reproduction and metabolism of microorganisms will produce a large amount of colloidal substances, which will cause the membrane to be blocked and cause a sharp decrease in the membrane flux; second, it will cause an increase in the total number of bacteria in the produced water. It is extremely unfavorable for the long-term operation of the entire device, so great attention should be paid to the microbial contamination of the nanofiltration membrane.

How does nanofiltration membrane technology decolorize xylose?

Xylose is a component of xylan derived from plant and animal heparin, chondroitin and glycoproteins. In some glycoproteins, it is the linking unit between the sugar chain and serine (or threonine). So far, no free xylose has been found in nature. Xylose can provide intercellular communication for glycoconjugates of receptors on cell membranes. Secondly, xylose has antibacterial and antifungal effects, especially against Gram-negative bacteria and Streptococcus albicans, and can help the growth of intestinal probiotics.
