Abstract

The different polymeric membrane materials were fabricated using modifiers such as sulfonated poly(ether ether ketone) (SPEEK) and bentonite for effective ultrafiltration of proteins from dairy effluent. Polyvinylidene fluoride (PVDF), polyethersulfone (PES), polyetherimide (PEI), polyamide-imides (PAI), cellulose acetate (CA), and polyphenylsulfone (PPSU) were selected for modification. Membrane morphology and functional group analysis were characterized using scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FTIR). Pure water permeability (64.66 × 10^-9 m/s kPa) was higher for the PES/SPEEK/bentonite membrane when compared with other polymeric membranes. Contact angle (54.05°) value was lower for CA/SPEEK/bentonite membranes and which indicates that hydrophilicity has got enhanced. The membrane performance was tested using model dairy wastewater by ultrafiltration under longer run mode. Further it was evaluated using resistance in series model. This study infers that modification of membranes using charged SPEEK polymer and nanofiller as bentonite can be used to alleviate the fouling in the treatment of dairy wastewater.
