    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.

    摘要: The invention relates to a facility which comprises an evaporation device (1'), which comprises an evaporation chamber (10) intended for containing water (11) in liquid form and allowing only a portion of the water contained in the evaporation chamber (10) to be evaporated, and gas-supply means (12) for injecting a gas into the water (11) contained in the evaporation chamber (10), such as to form gas bubbles in said water, and a heat exchanger (3), which comprises cooling means (300, 310, 311 / 300, 301) and which allows at least the water vapour from the evaporation chamber (10) to be condensed. The facility comprises water-supply means (14), which make it possible to pump water in liquid form (L) in a natural environment, to send said water pumped in a natural environment through said cooling means (300, 310, 311 / 300, 301) or to bring said water into contact with said cooling means (300, 310, 311 / 300, 301), such as to allow the cooling of the water vapour from the evaporation chamber (10), and to supply the evaporation chamber (10) with said water after said water has been heated, having passed through or been brought into contact with said cooling means (300, 310, 311 / 300, 301). The evaporation chamber (10) comprises means (10c; 143) for discharging a portion of the water in liquid form (L) contained in the chamber which, in combination with the water-supply means (14), make it possible to renew the water inside the chamber such that the temperature of the water contained in the chamber (10) is kept at a temperature that is sufficient for maintaining the evaporation of a portion of the water contained in the evaporation chamber (10).

    摘要: Gegenstand der Erfindung ist ein Verdampfer (1), der mit einer Umwälzleitung (2) sowie mit per se bekannten Mitteln ausgestattet ist, um die zu verdampfende Flüssigkeit im Kreislauf zu führen. Dieser Verdampfer (1) zeichnet sich dadurch aus, dass eine Luftzuführung (6, 6') vorgesehen ist, die entweder im Verdampfer (1) unterhalb des Flüssigkeitsspiegels (5) im Verdampfer (1) in die zu verdampfende Flüssigkeit mündet und/oder in der Umwälzleitung (2) mündet. Gegenstand ist ferner ein Verfahren zum Eindampfen, Eindampfkristallisieren, Vakuumkühlkristallisieren oder Vakuumkühlen in einem Verdampfer, bei dem die zu verdampfende Flüssigkeit mit Hilfe von per se bekannten Mitteln durch eine Umwälzleitung im Kreislauf geführt wird. Dieses Verfahren ist dadurch gekennzeichnet, dass Luft unterhalb des Flüssigkeitsspiegels im Verdampfer in die Flüssigkeit und/oder in die in der Umwälzleitung im Kreislauf geführte Flüssigkeit eingeleitet wird. Dadurch wird erreicht, dass eine störende Kurzschlussströmung verhindert oder zumindest verringert werden kann.
