  • Process for separating oil from emulsions of oil in water
    Patent number: 3931005
    Abstract: At least one iron salt and a sodium hydroxide solution are added to an emulsion of oil in water to adjust a pH value of 5.5 to 6.5. An intimate mixture is formed as said steps are performed. The mixture is left until a layer of iron hydroxide having a high oil content has creamed. When said flotation has resulted in a separation of phases, the oilfree water is withdrawn first and the oil-containing sludge is withdrawn thereafter.
