Analysis of fouling mechanisms in TiO2 embedded high density polyethylene membranes for collagen separation

- HDPE/TiO2 membranes were successfully fabricated via TIPS method.
- Incorporation of TiO2 nanoparticles increased surface roughness of the membranes.
- Fouling properties of membrane were analyzed using classic and combined models.
- Membrane containing 0.50-1 wt.% TiO2 showed reversible fouling properties.
- Neat HDPE membrane showed irreversible fouling property.
