Application Of Nanofiltration Membrane In The Separation Of Amoxicillin From Pharmaceutical Wastewater
Separation of amoxicillin from pharmaceutical wastewater by
nanofiltration (NF) membrane has been investigated in this study. For
this purpose a membrane system including a polyamide spiral wound NF
membrane was evaluated for the treatment of amoxicillin wastewater. The
effects of operating conditions such as flow rate, pressure and
concentration of amoxicillin and COD in the feed, on the efficiency of
the membrane were evaluated. The permeation flux and rejection of
amoxicillin and COD were the criteria for this evaluation. The
rejection of the amoxicillin by the selected NF membrane was adequate
and in most cases exceeded 97% whereas COD reached a maximum of 40%
rejection and permeation flux was over 1.5 L/min.m2. The rise in
pressure enhanced the transport rate of the solvents. Permeation flux
of the NF membrane increased with increasing flow rates. Experimental
data also indicated that concentration polarization existed in this
membrane separation process. The stable permeation flux and high
rejection of amoxicillin indicated the potential of NF for the recovery
of amoxicillin from the pharmaceutical wastewater
