What is Nanofiltration Membrane

On July 7, the product manager of Beijing Tri-High Membrane Technology Co came to our company to discuss about ultrafiltration membrane and other related products.

We had a deep discussion on the type of ultrafiltration membrane, production process, product details and related market, and discussed the future cooperation plan.

What is Ultrafiltration Membrane

Ultrafiltration is a membrane filtration process that acts as a barrier to separate harmful bacteria, viruses and other contaminants from clean water. Ultrafiltration water systems force water through a 0.02 micron membrane. Suspended particles that are too large to pass through the membrane adhere to the outer surface of the membrane. Only fresh water and dissolved minerals pass through.

What contaminants can be removed by UF membranes?

UF membrane is very effective in reducing rust, sediment, chlorine taste and odor, benzene, cryptomeria, bacteria; it also partially reduces algae, chlorides, copper, lead, mercury; and it has no effect on chemicals and TDS.

What is the difference between ultrafiltration and reverse osmosis?

Both ultrafiltration and reverse osmosis are physical filtration, using pressure to push water through a semi-permeable membrane, blocking impurities larger than the membrane pore size on the outer surface of the membrane.

The main difference between them is the filtration accuracy. Ultrafiltration membranes have pore sizes ranging from 0.01 to 0.1 microns, while reverse osmosis membranes have finer pore sizes of 0.0001 microns. Therefore, RO membranes can remove finer impurities, such as TDS.
