Dairy industry wastewater was treated by a micellar‐enhanced ultrafiltration (MEUF) process. Sodium dodecylbenzene sulfonate and Tween‐80 were used as anionic and non‐ionic surfactants, respectively, along with the dairy industry wastewater sample. A deep eutectic solvent (DES) membrane was prepared by phase inversion via non‐solvent immersion precipitation. The DES (choline chloride/urea) as pore‐forming agent was synthesized and added into the casting solution at various concentrations and blended to form a membrane, using a dead‐end filtration setup. The prepared membranes were characterized to examine the presence of functional groups and the surface morphology. The permeate flux and rejection performance of the prepared membranes were investigated. The newly developed MEUF membrane is promising for the treatment of dairy effluents.
