Abstract

-carboxymethyl chitosan(NOCC)composite nanofiltration(NF)membranes were prepared by coating and cross-linking.The fermentation effluent from a wine factory was treated with the resulting NOCC/polysulfone(PSF)composite NF membranes.The permeate flux and the removal efficiencies of the resulting NF membranes for the color

chemical oxygen demand(COD

)

total organic carbon(TOC)

and conductivity of the fermentation effluent were investigated in relation to the driving pressure

the feed flow

and the operation time.The permeate flux and the removal efficiencies were found to increase with the increase of the driving pressure or the feed flow.At 0.40 MPa and ambient temperature the removal efficiencies were 95.5%

70.7%

72.6%

and 31.6%for color

COD

TOC

and conductivity

respectively.The membrane was found to be stable over a 10h operation for the fermentation effluent treatment.
