“…The COD is lower for Samples N1 and N3 and differs by 8%, while the COD difference between N2 and N3 exceeded 23%. Higher organic pollutant content in Sample N2 caused an increase in cake layer formation (Tanis-Kanbur et al, 2018) and consequently lower emulsion flux. The limiting flux of 100 L/(m 2 •h) was reached with acidic samples N1 and N3, as shown in Fig.…”

Membrane surface properties and their effect on the efficiency of ultrafiltration (UF) of real waste oily emulsions was studied. Experiments were performed in cross-flow operation at total recycle condition in a lab-scale system. The ceramic UF membrane in the tubular type module was employed. During the experiments permeate flux was measured. The most important influential factors, such as temperature, TMP, and pH, were considered during the experiments. Zeta potential was measured in order to explain the phenomena on the membrane surface. The isoelectric point of the fouled membrane was shifted to the alkaline range. COD removal efficiency reached 89%. Gas chromatography measurements were performed in order to determine the composition of waste emulsions. SEM micrographs showed the formation of calcite on the membrane, which contributed to membrane fouling. Chemical cleaning was examined using alkaline and acid solutions, and a cleaning strategy was determined.

“…8. Most likely, negatively charged surfactants are attached to the membrane surface and influence its surface charge (Tanis-Kanbur et al, 2018). As the conductivity is very high, it is assumed that many charged ions are present in waste emulsion, and contribute to the membrane surface charge.…”

“…The shape and charge of the surfactant head can significantly affect the fouling tendency. The latest study by Tanis-Kanbur et al evidenced that the highest critical flux was obtained in the absence of surfactant stabilization due to the stronger oil-water interaction over oil-membrane interaction, hence the oil droplets remain in the bulk aqueous feed [63]. When the oil emulsion was stabilized with cationic surfactant dodecyltrimethylammonium bromide (DTAB), the lowest critical flux was achieved as the weak oil–oil repulsion has resulted in the extensive coalescence of the oil droplets.…”

View full text Add to dashboard Cite

Oily wastewater discharge from various industry processes and activities have caused dramatic impacts on the human and environment. Treatment of oily wastewater using membrane technology has gained worldwide attention due to its efficiency in removing the amount and concentration of oil and grease as well as other specific pollutants in order to be reused or to fulfill stringent discharge standard. The application of thin film composite (TFC) membrane in reverse osmosis (RO) and forward osmosis (FO) for oily wastewater treatment is an emerging and exciting alternative in this field. This review presents the recent and distinctive development of TFC membranes to address the issues related to oily wastewater treatment. The recent advances in terms of TFC membrane design and separation performance evaluation are reviewed. This article aims to provide useful information and strategies, in both scientific knowledge advancement and practical implementation point of view, for the application TFC membrane for oily wastewater treatment.
