“…5–8 Several treatment technologies for oily wastewater, such as floatation, adsorption, coagulation, flocculation as well as membrane–separation processes have been employed to mitigate negative effects caused by oily wastewater and other harmful organic foulants found in wastewater. 9–11 However, membrane technology has proven to be one of the most desirable due to its simplicity of operation, cost effectiveness and low requirements of energy. 12–15 In addition, membrane technologies utilize recyclable materials, are made up of compact systems and do not generate secondary pollutants which are unavoidably created in other wastewater treatment techniques ( e.g.…”
