ABSTRACT
In this paper, we have reviewed the application and efficiency of MicellerEnhanced Ultrafiltration (MEUF) method which is used to remove HeavyMetals, Dyes, Polyaromatic Hydrocarbons (PAH), Novel Compounds,Chromium, Phosphorous and Phenolic Compounds. It uses various surfactantslike Hexadecylpyridinium chloride (CPC), Sodium Dodecyl Sulphate (SDS),Hexadecyltrimethyl Ammonium Bromide (CTAB), Oxyethylated MethylDodecanoate (OMD) and Alkylpolyglucoside (APG). These surfactants areretained after the process to be reused. Bisorption, Coagulation, polyelectrolyteenhanced ultrafiltration, Reserve Osmosis, Nanofitration are some of themethods that are used for the treatment of wastewater. Available researchfocused on the removal of metals, phenol, organic & inorganic materials,aromatic hydrocarbons by MEUF mainly on the type of surfactant used,surfactant concentration, applied pressure, operating time and pH. Formation ofsurfactant micelle and mechanisms for the attraction between micelle and metalions are ignored during the research study on MEUF. It has been reported thatMEUF combines the efficacy and simplicity of the conventional options with theoperational flexibility of membrane-based separation. MEUF could be used forremoval of wastewater provided the pollutants have low molecular weight.Higher reagent and electrical costs are reported in conventional MEUF methodas compared to the hybrid process with MEUF. The hybrid process requiresfewer surfactants. MEUF is considered a better alternative to the typicallyavailable membrane separation processes. The advantages of this method overother methods are high removal efficiency, low energy consumption, and easyoperation. The selection of surfactant for the removal purpose is based on thetarget pollutants.Keywords: Miceller Enhanced Ultrafiltration; Surfactant; Micelles;Polyaromatic Hydrocarbon; Novel Compounds.
