Wastewater from refineries and petroleum plant lead to severe environmental pollution. There are various ex- isting processes applied for oily water treatment, but membrane-based technology is one of the most efficient methods. Polymeric membranes prepared from organic materials for the separation of oil in water often face chronic problem of mem- brane fouling. Inorganic membranes are considered to be more efficient due to longer lifetime than organic membranes. Zeolite membranes have better chemical stability and long-term recyclability. The presence of hydrophilicity enhances the water flux of membrane. Ceramic membranes prepared from zeolites are another efficient class of inorganic membranes ap- plied for oil water separation. This review is focused on oily wastewater separation based on zeolite membrane which classi- fied into two categories, i) neat zeolite and ii) zeolite composites with other materials.
