Synthesis and application of a composite NaA zeolite/gamma-alumina membrane for oil-water separation process

Abstract This study proposed the development of an efficient membrane composed of zeolite-alumina to be used for water-oil separation of wastewater effluents contaminated by oil extraction processes. The efforts made to care for the environment and to decontaminate bodies of water are extremely valuable and constantly being updated. Little research has been done on this subject and this study contributed to remedying this lack. Membrane technology is a reasonable alternative to conventional procedures if economics and eco-sustainability are considered. The objective of this study was to examine the performance of a composite membrane produced through mechanical mixing. The potential of the composite membrane (NaA zeolite/gama-alumina) to separate oil-water emulsions was tested. The results obtained demonstrated that the composite membrane is an excellent alternative for the oil/water emulsion separation process; the membranes are efficient and low-cost alternatives for treating oily wastewater.
