We fabricate a novel cellulose acetate (CA) ultrafiltration membrane modified by block copolymer F127-b-PDMAEMA, which is synthesized using F127 and DMAEMA via the ARGET ATRP method. Compared to conventional ultrafiltration membranes, the incorporation of both F127 and PDMAEMA can not only readily increase the hydrophilicity of the membrane, but also exhibit stimuli-responsiveness to temperature and pH. Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (NMR), and gel permeation chromatography (GPC) are employed to analyze the structure of the F127-b-PDMAEMA. The membrane properties are evaluated via scanning electron microscope (SEM) imaging, porosity test, automatic target recognition Fourier transform infrared spectroscopy (ATR-FTIR), water contact angle test and permeation test. The results indicate that the F127-b-PDMAEMA is an excellent pore agent, which contributes to an enhancement of the membrane in sensitivity to temperature and pH. The modified membrane also exhibits lower water contact angle (64.5°), which is attributed to the good anti-fouling performance and high water permeation.

a b s t r a c tIn the present study membrane filtration was applied for the purification of crude oil containing stable oil in water emulsions (c oil = 100 ppm; d oil droplets < 1.5 µm) with and without pre-ozonation using polyethersulfone (PES) microfiltration membrane (d pore = 0.2 µm). The effect of ozonation on the size of oil droplets and on Zeta-potential was determined by dynamic light scattering measurements. The effects of applied transmembrane pressure, stirring speed and duration of ozonation were investigated in detail. Removal efficiency was determined by measuring turbidity, chemical oxygen demand (COD), total organic carbon content (TOC) and extractable oil content (TOG/TPH). Results pointed out, that short pre-ozonation (absorbed ozone was 30 ± 5 mg L -1 ) causes increased fluxes and decreased resistance without notable change in the purification efficiency in case of low transmembrane pressure (0.1 MPa). However longer pre-ozonation or higher transmembrane pressure results in increased irreversible resistance, lower permeate fluxes or even lower purification efficiency.

“…Since polyethersulfone is one of the most extensively used material to produce nano-, ultra-, and microfilter membranes [4,23,24,41], because of its chemical-and thermal stability, easy processing and environmental endurance [4,42], therefore in the present study polyethersulfone microfilter was used to eliminate the oily contaminants with and without the destabilization pretreatment. Permeate fluxes, resistances, fouling models and purification efficiencies were investigated in both cases.…”

ABSTRACT. In the present study the purification of finely dispersed oil contaminated water (100 ppm crude oil; doil droplets<2 µm) was investigated by using coagulation/flocculation process, membrane separation and combined methods. As coagulant, polyaluminum chloride (Bopac) iron(III) chloride and aluminum(III) chloride, while as flocculant anionic polyelectrolyte were applied. For the membrane separation, hydrophilic polyethersulfone (PES) microfilter (d=0.2 μm) was used, while for the determination of the purification efficiencies turbidity, chemical oxygen demand and extractable oil content were measured. The utilization of Bopac polyaluminum chloride coagulant (by setting Al 3+ content to 20 ppm) resulted in high purification efficiency (96.7%). The extra addition of 1 ppm anionic polyelectrolyte lead to the increase in efficiency up to 98.8%. Due to the effective destabilization of oil in water emulsion the flux highly increased during the microfiltration of the emulsion, since both irreversible and reversible membrane resistances were greatly reduced.
