    Abstract: Inorganic species are removed from liquid streams such as waste water streams by treatment with an emulsion of reagent-containing aqueous droplets suspended in an organic liquid containing surfactant which forms a membrane around said aqueous droplets. The inorganic species, such as phosphates in waste water will permeate the membrane; the reagent within the droplet is such that it will react with the permeating inorganic species to form a new compound which will precipitate and remain within the droplets. The emulsion is then removed from the system.

    Abstract: Organic compounds are removed from waste water streams by treatment with an emulsion of aqueous droplets containing a reagent coated by an organic liquid membrane containing surfactants through which the organic compounds in waste water will permeate and react in the aqueous droplets to form new chemical compounds and from which they can be recovered eventually by flashing off or emulsion breakup. The formation of new chemical compounds in the aqueous droplets prevents the organic compounds from permeating out of the emulsion. In a preferred embodiment of the invention phenol is removed from waste water streams.
