Membrane Fabrication And Application For Removal Of Pollutant From Wastewater

Abstract

: Dye contamination of wastewater has become one of the most critical environmental problems these days and can have adverse impacts on human health if discharged without any treatment. There are various techniques for the removal of dyes from wastewater such as adsorption, oxidation process, photocatalyst, biological decolorization, membrane separation technology, etc. In the present work, we have fabricated a polyvinylidene fluoride (PVDF) and membrane was modified by dispersing nano-sized titanium (IV) oxide (TiO2) particles in a PVDF solution. PVDF flat-sheet composite membranes were synthesized using a phase inversion method. Polyester Nonwoven fabric was used as the support layer. Membranes fabricated with support had good mechanical, thermal strength than membrane fabricated without support. We have applied the synthesized PVDF flat sheet composite membrane for the removal of Acid Blue 113 dye of concentration 100 mg/L from wastewater. PVDF/ TiO2/ non-woven polyester support membrane, PVDF/ polyester support membrane and pure PVDF membrane showed the 67.64%, 48.34% and 32.25% of Acid blue 113 dye removal, respectively. Experimental results indicated that the dye removal was found to increase with increasing the TiO2 concentration in membrane matrix. PVDF/TiO2/polyester non-woven support membrane showed the maximum Acid Blue 113 dye removal than pure PVDF membrane and it has a significant potential for the treatment of dye bearing wastewater.
