Characterization of Two Nanofiltration Membranes for the Separation of Ions from Acid Mine Water
We evaluated nanofiltration for separation of
ions from acid mine drainage (AMD), using two composite
nanofiltration membranes (Nano-Pro-3012 and NF90) as
examples of the polyamide class of acid-stable membranes.
The structure of the NF membranes was characterized by
scanning electron and atomic force microscopy. The NF90
displayed a higher permeate flux than Nano-Pro-3012, with
higher relative roughness at both pH values. Both membranes
suitably rejected most of the metals found in the
AMD, but the Nano-Pro-3012 membrane proved unsuitable
for sulphate remova
