What is Ultrafiltration?

What is Ultrafiltration?

  1. Membrane needs to retain large molecules or colloidal particles
  2. Smaller Molecules pass through along with the water
  3. No significant Osmotic Pressure
  4. Typical Operating Pressure 10-100 PSI

Performance of Ultrafiltration Systems

  1. Flow across Membrane Surface
  2. Operating Pressure
  3. Operating Temperature
  4. Recovery
