Reactor fouling
WebThe average pH in the reactor was 7.2 ± 0.4. As a result, the recirculation of the anoxic gas was successfully applied to control the membrane fouling in the anoxic MBR. AB - Anoxic gas recirculation system was applied to control the membrane fouling in pilot-scale 4-stage anoxic membrane bioreactor (MBR). WebFouling of a reactor zone is partially overcome by a periodic increase of the reactor pressure by means of the operation of a control valve located near the reactor exit. The periodic operation of the valve results in an increase of the velocity of the reaction mixture that tears away the polymeric deposits.
