Ultrafiltration

Ultrafiltration: A process for effective water treatment

Ultrafiltration is a pressure-driven filtration process. Ultrafiltration membranes have a pore size ranging from 0.01 to 0.1 µm and can retain viruses, bacteria, other microorganisms, proteins, and other macromolecules.

Ultrafiltration offers an effective and efficient method for purifying and treating water, especially for applications where high purity and quality are required.

What is Ultrafiltration?
“Ultrafiltration” might sound huge, and indeed, the process behind it is quite complex. In simple terms, the function of an ultrafiltration system works as follows: Inside, there is a polymer membrane. Due to the extremely fine pores of this membrane, even the smallest dirt particles can be easily removed from the water. Ultrafiltration is thus the perfect pre-treatment for raw waters with seasonally fluctuating particle loads. These raw waters can first be pre-treated before undergoing further processes, such as water desalination via ion exchange.

Advantages of Ultrafiltration using EnviroFALK Filter Systems

• Retention of fine particles due to the small pore size of the ultrafiltration membrane
• Ideal pre-treatment for subsequent membrane processes, such as reverse osmosis or electrodeionization (EDI)
• Easily automatable process in the ultrafiltration system through PLC control
• Increasingly cost-effective production of ultrafiltration membranes and ultrafiltration membrane units
