摘要:
Die Erfindung betrifft ein Verfahren zum Versetzen einer Flüssigkeit mit einem Gas unter Verwendung eines Gas-Flüssigkeits-Kontaktors (1) mit einem Gehäuse (2), in dem eine Vielzahl von Hohlfasern (3) angeordnet ist und ein die Hohlfasern (3) umgebender Raum (9) ausgebildet ist. Die Erfindung zeichnet sich dadurch aus, dass die mit Gas zu versetzende Flüssigkeit (4) und das Gas (12) durch den Gas-Flüssigkeits-Kontaktor (1) im Gegenstrom strömen und dass der Gas-Flüssigkeits-Kontaktor (1) eine Fluidverteileinrichtung mit einer ersten Seite (18) und einer zweiten Seite (19) und einer Vielzahl von Durchbrüchen (8) aufweist, die sich von der ersten Seite (18) zur zweiten Seite (19) erstrecken und durch die die mit Gas zu versetzende Flüssigkeit (4) strömt. Dabei weist die Fluidverteileinrichtung (7, 13) ferner einen Innenraum, der von der ersten Seite (18) und von der zweiten Seite (19) begrenzt wird und der gegenüber den Durchbrüchen (8) fluiddicht ausgestaltet ist, eine Vielzahl von Öffnungen (10), die den Innenraum mit der zweiten Seite (19) verbinden, und einen Fluidanschluss (14, 15), durch den das Gas (12) in den Innenraum eingebracht oder aus dem Innenraum ausgebracht wird, auf.
摘要:
A micro-bubble generating device is provided which is capable of mixing or dispersing micro-bubbles into a liquid with high stability and has a simple structure that permits reduction of a cost of manufacture. A first member and a first packing are superposed on each other on one side of a gas-permeable film, while a second member and a second packing are superposed on each other on the other side of the gas-permeable film. A pressurized gas delivered via a gas inlet of the first member flows through a fluid passage of the first packing, permeates through the gas-permeable film, and is ejected as micro-bubbles into a liquid flowing through a fluid passage in the form of a narrow shallow strip-like groove provided in the second packing.

The invention relates to a method for stirring and/or aerating fluids, particularly sewage, having the following cyclically repeated steps: aerating the fluid by means of an immersed aerator for a predetermined first period of time (t1) using an aeration device (1) disposed on a carrier (3, 43) designed as a floodable hollow body (2, 42), the hollow body (2, 42) being flooded and air being brought into the fluid by the aeration device, whereby the potential for nitrification is created in the fluid; stirring the fluid by means of the immersed aerator for a predetermined second period of time (t2), the air infeed by the aeration device (1) being throttled or turned off, and the previously flooded hollow body being evacuated in order to fill the hollow body (2, 42) with gas or air, the immersed aerator assuming the function of a mixing device in which fluid rises upward, thus mixing the fluid, wherein the potential for denitrification is created in the fluid; and an immersed aerator.

An apparatus for producing an aqueous carbonic acid solution which is equipped with a carbon dioxide dissolving vessel (3) and a circulating pump (1) and which circulates the water in a bath (11) by the circulating pump (1) and supplies carbon dioxide into the carbon dioxide dissolving vessel (3), to thereby dissolve carbon dioxide in water, characterized in that the circulating pump (1) is a volumetric metering pump having the ability of self-suction; a method for producing an aqueous carbonic acid solution which uses the apparatus; a method for producing an aqueous carbonic acid solution which comprises starting the formation of an aqueous carbonic acid solution and maintaining a desired concentration of an aqueous carbonic acid solution; an apparatus for producing an aqueous carbonic acid solution which is equipped with a means for adjusting a pressure of supply of carbon dioxide so as to achieve a desired concentration of carbon dioxide; an apparatus for producing an aqueous carbonic acid solution which automatically releases a drain to outside; and an apparatus for producing an aqueous carbonic acid solution which is equipped with a transportable bath with legs.
摘要:
An apparatus for producing a carbonated water which comprises allowing water to pass through a first carbonic acid gas dissolving device (7) to dissolve a carbonic acid gas in water, and then allowing the carbonated water having passed through the first carbonic acid gas dissolving device (7) to pass through a static mixer (13) as a second carbonic acid gas dissolving device; and a method for producing a carbonated water using the apparatus. The above apparatus has a simpler structure as compared to that of a conventional apparatus and allows the production of a carbonated water having a high content of a carbonic acid gas, with greatly enhanced efficiency and with ease.
摘要:
A diffuser assembly (14) diffuses a fluid into a medium to aerate the medium. The diffuser assembly (14) includes a diffuser body (16) in fluid communication with a fluid source and a membrane (18) connected to the diffuser body (16). The membrane (18) is circular and includes a slitting pattern divided into a series of similar angular segments (22). The segments (22) are positioned adjacent each other in a circular arrangement to substantially cover the membrane (18). Each segment (22) includes a plurality of rows (24) each having a plurality of slits (26). The slits (26) within the segment (22) are arranged in a parallelogram pattern. A first line (b) extending between adjacent slits (26) in a common row (24) is substantially the same length as a second line (a) extending between adjacent slits (26) in adjacent rows (24).
