METHOD FOR INDUSTRIAL WATER TREATMENT

摘要

The invention relates to a method for separating fluorine-containing surfactants out of industrial water, comprising the method steps of: a) providing the industrial water having at least one fluorine-containing surfactant, wherein the fluorine-containing surfactant has a concentration below a foam forming concentration in the industrial water; b) generating gas bubbles in the industrial water while forming an aerosol on the surface of the industrial water; and c) separating the aerosol from the industrial water. To summarise, the method according to the invention creates a means, which can be easily carried out and is cost-effective, for separating fluorine-containing surfactants out of industrial water in a particularly effective manner. For example, such industrial water can be process water or waste water from a galvanic process or extinguishing water or ground water.
