FOULING OF MEMBRANES

(biogrowth and precipitation)

Surface Modification

- Surface deposition of non-reactive metals

using electroless plating, e.g., Pd, Pt, etc.

- Deposition layer thickness ~ 1-3 microns (low

cost)

- Hollow fiber retains porosity and flexibility

Pressure Pulsing

- Frequent pressure pulsing results in sloughing-

off action of surface deposits and growth

- Prevents concentration polarization
