Abstract:
Recently, dye has been broadly used in many applications especially in industries.
Discharged of dyes wastewater generates large volumes of effluents on a daily basis,
which contains substantial loads of organic compounds, inorganic salts, and
suspended impurities. Polysulfone nanofiltration membrane had been applied for dye
containing wastewater treatment. However, one of the disadvantage of polysulfone is
it easy to cause fouling onto the membrane surface. So, to overcome this problem,
nanoclay, alkyl phosphonium montrnorillonite (APM) was used to decrease the
fouling and to increase hydrophilicity. In this study, the effects of polysulfone/alkyl
posphonium montrnorillonite nanofiltration membrane on efficiency of dyes removal
from wastewater and able to improve the overall performance were determined.
Polysulfone (PSf) of 19 wt% and 21 wt% were used as the polymer backbone for
nanofiltration (NF) membrane and alkyl phosphonium montmorillonite (APM) consist
of range of 0.0 wt%, 0.1 wt%, 0.5 wt% and 1.0 wt% were used as nano-composite
material in order to improve hydrophilicity of the native membrane property.The
Nanofiltration membranes were fabricated using dry/wet phase inversion technique
with an electrical casting machine.
