- •
Constant flux deposition of layer-by-layer polyelectrolytes turn UF hollow fiber membranes into backwashable NF membranes.
- •
Permeated volume and rejected polyelectrolyte mass precisely determine selectivity and flux.
- •
Method can be applied on already existing hollow fiber membrane modules as a post-treatment.
