Functionalized porous filtration media for gravity-driven filtration: Reviewing a new emerging approach for oil and water emulsions separation

Oil and water separation technology has been continuously progressing throughout the years. Recently, gravity-assisted filtration has gained considerable attention, although most of the studies have focused on oil and water synthetic mixtures which can be easily separated under gravity. It is deemed challenging for mechanically and chemically stabilized emulsions to be separated without the addition of an external pressure other than static...
