Membrane Filtration Technology

1. Membrane Filtration

2. Membrane Filtration

3. Categorized into four processes based on membrane
pore size;
A. Microfiltration
B. Ultrafiltration
C. Nano filtration
D. Reverse Osmosis
Membrane Filtration

Algae, some bacterial
species and oil Emulsions.
Microfiltration

5. Used in :
purification of juices and beverages.
cold sterilization of pharmaceuticals.
separation of oil and water emulsions.
pre treatment of nano filtration or
reverse osmosis
…microfiltration

6. 0.003 to 0.1 microns
