Hollow Fiber Membranes and Water Filtration

Posted by Renovo Water on March 14, 2014. 0 Comments

The use of membranes for filtration can be traced back to 1830. However, the most accurate representation of the technology we have today was developed around 1960. The uses were for the reclamation of waste water, desalination, gas separation, and blood diffusion.

How do hollow fiber membranes work

Hollow fiber membranes are small hollow tubes that look like straws. These fibers have a porous membrane that allow clean water into the tube and prohibit contaminants from passing through the membrane. This is illustrated below:

More interesting facts

The hollow fiber membrane can be reclaimed by a process called back flushing where clean water travels through the filter in the opposite direction. This process cleans the pores of the membrane. Hollow fiber membranes can work in a variety of temperatures and climates though if left to freeze it can be damaged. Hollow fiber membrane technology has come along way and will continue to be used in various applications. Learn more about the Renovo Trio.
