Ultrafiltration

Ultrafiltration uses membrane filters with pore sizes of typically 1 to 10 nm which can remove particles as small as proten macromolecules. UF is an excellent technology for ensuring consistent ultra pure water quality with respect to particles, bacteria and pyrogens.

How Ultrafiltration removes particles from water

The water flow is directed straight through the membrane, or in "cross flow" fashion where a portion of the input water flows across the membrane surface to filter out most colloids, enzymes, microorganisms, particles and endotoxins above their rated sizes.

Advantages:

  • Effectively removes most colloids, removes most colloids, enzymes, microorganisms, particles and endotoxins above their rated sizes, keeping them above the ultrafilter surface.
  • Efficient operation
  • Lifetime can be extended by a regular high speed flush

Restrictions:

  • Does not remove dissolved inorganic or organic substances
  • Can block if presented with a high level of molecular weight contaminants
