Membrane method is based on the difference in rates of diffusion through the polymer membrane.
The membrane separation
Ultrafiltration – Continuous process
• Punching through a porous membrane
• Removal of suspended solids, organic matter and microorganisms
• Types: a dead-end filtration and tangential
Desalination:
• Filtration
• scavenger
• Ion exchange filters
– Counterflow
