Hollow Fiber Membrane
Hollow fiber membranes, or Ultrafiltration, are used to remove particulate and molecules from contaminated water. Hollow fiber works through size exclusion. The hollow fiber tubes have thousands of tiny holes (0.1 microns) that block 99.9999% of harmful bacteria, Giardia, E. coli, protozoan cysts, Cryptosporidium and more. All of these organisms are too large to fit through the 0.1 micron holes. Some of benefits of using hollow fiber are; there are no chemicals required, you can backflush the fibers to remove particulate and increase life of the filter, hollow fiber exceeds regulatory standards of water quality, and there is no shelf life for the fiber.
Using the same ultrafiltration technology viruses can be excluded. With holes measuring 0.02 microns, rather than the traditional 0.1 mircons, the dangerous viruses are removed and viruses such as Hepatitis A, Polio, Typhoid, Enteroviruses, and more are filtered out. Additionally, this same filter can block 99.999% of bacteria as the tiny holes are much smaller which creates secure barrier from contaminates.
Hollow fiber is used in many different industries, including, chemical and pharmaceutical manufacturing, food and beverage processing, blood dialysis, and waste water treatment.
