Abstract: The present invention relates to a device, particularly a nozzle, for treating waste water, said nozzle having an outer tube and an inner tube. An intermediate space is formed between the outer tube and the inner tube and said intermediate space between the outer tube and the inner tube is divided into at least two chambers in the longitudinal direction of the tubes. The inner tube tapers in the longitudinal direction and then widens again and has at least one opening into each chamber at the constricted area. On the inner side of the inner tube and/or in the interior thereof, the device preferably has a catalyst. The present invention further relates to a method for oxidising polluted waste water and a system for performing the method.

Abstract: The invention relates to a device (1) for adding chlorine dioxide to water, comprising a first feed line (5a) for feeding a first reaction component, a second feed line (5b) for feeding a second reaction component, a mixing tube (2) for mixing and reacting both reaction components to form chlorine dioxide. Both feed lines (5a, 5b) open into one end of the mixing tube, and at the other end of the mixing tube, a suction chamber (4) is disposed, into which feed water to be enriched with chlorine dioxide can be injected by means of a nozzle (12). The device further comprises a wastewater line (13) leading downstream out of the suction chamber (4). The aim of the invention is to further develop such a device such that said device has a simple and robust design and allows for chlorine dioxide syntheses that are based on two reaction components to be carried out safely. Said aim is achieved by providing the mixing tube (2) with an admission opening (10) for admitting reaction-component-free admitted water to be enriched with chlorine dioxide.

Abstract: A generator device to produce a fluid stream comprising bubbles includes a casing having an inlet port and an outlet port through which water comprising contaminates flows with the casing having a region that constricts fluid flow between the inlet port and the outlet port, a pair of feed ports that receive fluids supported by the casing and a pair of microporous sleeve members disposed in an longitudinal relationship with the outer casing, and spaced from an inner surface of the outer casing, the pair of microporous sleeve members containing microporous media disposed within a space defined between the sleeve members, with at least one of the pair of feed ports that receive the fluid coupled to deliver the fluid through the microporous media. Bubble generator devices produce a fluid stream comprising bubbles to treat waste and/or frac-water.

Abstract: A dissolving apparatus (1) has a cylindrical tubular container (15) closed at both ends with its center axis being inclined to the horizon. A center of an interface (6) between a gas and a liquid in the container (15) is positioned at a center in a lengthwise direction of a side wall (13) of the container (15). Two inner spaces of the container (15) above and below the interface are referred to as a gas section (61) and a liquid section (62). An injection inlet (11) for injecting a gas-liquid mixed fluid into the container (15) is provided at a level corresponding to, or lower than, the interface (6). A liquid outlet (12) for discharging the liquid is provided near a bottom of the liquid section (62) of the container (15). Since the container (15) is inclined, the interface (6) can have an area large enough to promote dissolution of the gas into the liquid. Since the depth of the liquid in the liquid section (62) is sufficiently deep, the liquid can be prevented from being discharged through the liquid outlet (12) with large gas bubbles being present therein.
