    摘要: A bioreactor vessel (13) includes an open-ended tank (14) having suspended therein an air supply means (15) adapted to inject air into a liquid (16). The bottom member (17) is sealingly mounted with sidewalls (18), which has open port (20) and, the sidewalls define a constant tank diameter (21). The supply means (15) may include elongated tubular support shaft (22) which includes a longitudinal axis (24) which passes through the longitudinal axis (26) of the tank (14). Hollow riffle tubes (70) are fixedly mounted to shaft (22) for slurry flow which, after flowing through the riffle tube (70), impacts on the slurry (16) contained in the tank (14). Each radial arm (90), supported by support arm (96), extends outwardly from shaft (22) along longitudinal axis (107) and contains diffusers (100), which directs oxygen to the slurry (16). The diffusers include upright rigid frame structure (104) and a membrane fitted face (106). The membrane adheres to the sidewalls (110) whereby each compartment (114) is sealed. Each compartment (114) contains aperture (115) for measuring CO2 concentrations. Fitted on the lower surface of radial arm (90) are scrapers (117) to collect solids. In one construction, radial arm (90) and support (96) are mounted on cylindrical sleeve (121) which is made rotatable with shaft (22). Positioned in the upper region of the tank (14) is the bridge support (112).

    摘要: A reactor for the production of plasmids and bacteriophage uses a standard centrifuge bottle (10) to hold a sample. In the device, a column (16) is removably placed on the bottle (10) and has a gas delivery and venting system for aerating and mixing the sample. A port is disposed in the column for sampling and injection of reagents. At the completion of bacterial growth, the device is removed from the centrifuge bottle (10), which is transferred to a centrifuge for further processing.

    摘要: A method and apparatus for generating microbub­bles in a flowing liquid stream for use in a froth flota­tion system. The system utilizes a microbubble generator (50) having a tubular housing (53) with an inlet end (51) and an outlet end (52). Located coaxially within the housing (53) is an inner member (90) with an elongated exterior cylindrical surface. A porous tubular sleeve (80) is mounted between the housing (53) and the inner member (90) coaxially therewith to define with the cylindrical interior surface of the housing (53) an elongated air chamber (85) of annular cross section. The porous sleeve (80) also has a cylindrical inner surface that defines with the exterior surface of the inner member (90) an elongated liquid flow chamber (99) of thin, annular cross section. An aqueous liquid is supplied to the liquid flow chamber (99) at a rela­tively high flow rate and air under pressure is supplied to the air chamber (85) so that air is forced radially inwardly through the porous sleeve (80) to be diffused in the form of microbubbles in the flowing stream.
