Effects of solubility parameter differences among PEG,PVP and CA on the preparation of ultrafiltration membranes:Impacts of solvents and additives on morphology,permeability and fouling performances
The effects of two different hydrophilic additives and two solvents on the membrane morphological structure
permeability property and anti-fouling performances of cellulose acetate (CA) ultrafiltration membranes were investigated. During the phase-inversion process
cellulose acetate was selected as a membrane forming polymer; polyethylene glycol (PEG) and polyvinyl pyrrolidone (PVP) were used as additives; acetone (Ac):
N
N
-Dimethylacetamide (DMAc) and
N
N
-Dimethylformamide (DMF) were used as solvents; and deionized (DI) water was used in the coagulation bath. All the prepared membranes were characterized in terms of hydraulic permeability (

m
)
membrane resistance
average pore radius
and hydrophilicity. The top surface and crosssectional view of the prepared membranes were also observed by using field emission scanning electron microscopy. Membrane fouling and rejection experimentations were done using a stirred batch-cell filtration set-up. The experimental studies of fouling/rinsing cycles
rejection
and permeate fluxes were used to investigate the eff
ect of PEG and PVP additives and effect of the two solvents on the fabricated membranes using bovine serum albumin (BSA) as a model protein.
