    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.
