PIGNAT Ultrafiltration For Food Processing – UFA3000


SKU: UFA3000 Category: Tags: , ,


Membrane characterisation:

  • Study with a domestic water network: determine the hydraulic resistance Rm of the membrane
  • Study the ultrafiltration of a macromolecule:
    • study the influence of the sweeping speed
    • study the influence of the macromolecule concentration
    • study gel layer formation
  • Study the ultrafiltration process
    • Open loop and closed loop ultrafiltration process
    • Procedure for cleaning the unit with bactericidal solutions.

Proposed experiments:

  1. Concentrate a coloured aqueous solution
    • In an open loop
    • In a closed loop
  2. Characterise and compare membranes:
    • Plot the retention graph.
    • Determine the cutoff threshold and the conversion ratio.
  3. Study the process:
    • Influence of parameters: transmembrane pressure, flow rate.
    • Phenomena related to ultrafiltration: polarisation, clogging.
  4. Regenerate the membranes.
