摘要： The disclosed invention consists of a water oxidation method, comprising the treatment of micropollutants in bromide-containing water with ozone and hydrogen peroxide in an ozonation reactor (1), reaching reproducible low and homogenously distributed ozone concentration in the ozonation reactor. This avoids any residual of ozone in solution and therefore BrO 3 - formation. This goal is reached by a controlled addition of hydrogen peroxide to the water in a first step. The solution is then introduced in a multiplicity of hollow fiber membranes (20) permeable to gas, extended along the inner space (10) of the ozonation reactor (1). In parallel, ozone is added from the ozone filled inner space (10) of the ozonation reactor (1) with a controlled concentration (partial pressure?) through the hollow fiber membrane walls (200) in a homogenously distributed way without gas bubbles into the fiber compartments (201) carrying the water/hydrogen peroxide solution with an adjustable flow rate all along the entire hollow fiber membrane length (L).

摘要： The dual diffuser assembly (10) of the present invention includes a first (23) and second (24) diffuser body in fluid communication with an air distribution pipe (14). The diffuser assembly (10) further includes a saddle (16) that connects the first diffuser body (23) and the second diffuser body (24) to the distribution pipe (14). The fluid received from the distribution pipe (14) passes into the first and second diffuser bodies (23, 24) and exits the first diffuser body (23) through a first diffuser (35) and exits the second diffuser body (24) through a second diffuser (36). The first and second diffusers (35, 36) form the air into fine bubbles that serve to facilitate aeration of the medium.

摘要： A container assembly includes a flexible bag having an interior surface bounding a chamber and an opposing exterior surface, the bag having a top end wall, a bottom end wall, and an encircling sidewall extending therebetween, the bottom end wall including a first polymeric sheet overlying a second polymeric sheet. A first weld line welds the first polymeric sheet to the second polymeric sheet, the first weld line bounding a first sparging area formed between the first polymeric sheet and the second polymeric sheet. A plurality of first perforations are formed through a portion of the first polymeric sheet that overlies the first sparging area so that gas can pass from the first sparging area, through the first perforations and into the chamber of the bag.

摘要： The invention relates to a mixing vessel that includes a flexible container (2), a means (7) for mixing the content, and an aeration means (13). The vessel further includes a drain port/lower bearing (6, 11) having a rigid flange (16) with a drain passage (17), tightly attached to the lower portion (3a) of the container wall (3), and supporting a lower bearing adjacent to the drain passage. The mixing vessel further comprises an extended member (15a) for dispensing an aeration gas that is substantially radially spaced from the drain port/bearing. The at least one tubular member (14a) for dispensing the aeration gas extends from the extended dispensing member within the inner space and along the inner surface of the lower portion (3a) and the side portion (3b) of the wall (3) of the container (2), and extends outside the container from the upper portion (3c). At least one mixing member (10) is substantially spaced from the lower portion of the container wall, from the lower bearing, and from the at least one extended member for dispensing an aeration gas. The vessel of the invention is intended for receiving a bio-pharmaceutical mixture and for mixing the same.

摘要： A fermentation process uses substantially pure oxygen. The oxygen is the only reactive gas which is injected into a fermentation vessel. The oxygen is moved through the vessel solely by its own pressure. The process can be used with both mechanically-agitated and air-lifted fermenters. The mechanically-agitated fermenter includes an analyzer (35) for measuring oxygen concentration in the exhaust line, and adjusting the flow of fresh oxygen into the vessel accordingly. In the air-lifted fermenter, an analyzer measures the oxygen concentration in the head space of the vessel, and operates valves which either recycle the gas from the head space, or vent that gas to the outside, according to the measured concentration. A stream of nitrogen is periodically injected into the vessel to drive out carbon dioxide and other gases, to control the pH of the fermentation medium. The present invention substantially improves the efficiency of a commercial fermentation process.
