New anaerobic membrane bioreactor

Our company has launched a new product, anaerobic membrane bioreactor

MBfRThe total volume of the membrane bioreactor is2356mLThe volume of hollow fibers used for gas transportation is11mLThe volume used for fiber materials is45mL.MBfRThe working volume for liquid flow and biofilm growth is2300mL，MBfRfrom12Composed of hollow fiber membranes, methane is injected into the membrane cavity through a gas cylinder. Each bundle is composed of5 0 0Root hollow fiber(Non porous polypropylene hollow fiber)Composition, long30 cm, inner and outer fiber diameters90/2 0 0MmThe total surface area of the membrane is1.13m²One end of all fibers is connected to a methane cylinder(95%methane+5%carbon dioxide)The gas pressure of the internal hollow fibers is regulated by a regulator connected to the gas cylinder250 kPaManually adjust and monitor with a gas pressure gauge.

adopt20LThe inlet water tank stores synthetic wastewater containing nitrite and ammonia nitrogen. Therefore, ensureMBfRThe anaerobic operation is connected to a nitrogen filled feed tank20Lgasbag. Artificially synthesized wastewater enters the reactor through the inlet pump. By using a peristaltic pump for liquid reflux(600mL/min)Ensure the mixing of the reactor.
