Abstract
Membrane distillation-crystallization (MDC) is presented as a novel technique in the treatment
of waste concentrated water which produces valuable crystals along with pure water. In the
present study, multi-walled carbon nanotubes (MWCNT)/polyvinylidene fluoride (PVDF) flat sheet
membranes were prepared via the wet phase inversion method and applied in MDC for the
treatment of pharmaceutical waste. The pure and modified membrane surface properties are
characterized with the help of SEM, FTIR, and contact angle measurement. The present work
reported the effect of MWCNT content and feed temperature on the MDCperformance and
measured pure water flux and pharmaceutical compounds recovery. The observed maximum
permeate flux and crystal recovery for Salicylic acid system was 5.5 kg/m
2
h and 50%, respectively
for PVDF+0.5% CNT membrane and 5 kg/m
2
h and 48%, respectively for pure PVDF. Also, for
paracetamol system it was 3.9 kg/m
2
h and 41% for PVDF +0.5% CNT membrane and 3.5 kg/
m
2h and 38% for pure PVDF. Obtained results show that MDC has good potential in treating
pharmaceutical waste.
