- Abstract:
- The study was carried out for optimizing the separation mesh between the membrane area and the carrier area by using a baffle in a hybrid growth membrane bioreactor (HGMBR). The effects of the area and the location of the baffle on the hydrodynamic characteristics of the reactor were investigated by clean water experiment. It was found that the use of a baffle could improve the hydrodynamic characteristics of the reactor, mitigate the negative impact of the separation mesh on the mobility of the carriers, reduce the aeration rate required for driving the carriers, enhance the recirculation of the carriers in the reactor, and therefore reduce the energy consumption. The optimized operation results showed, when the closed design of a baffle (an area of 0.71 m2) on the upper part of the separation mesh between the membrane area and the carrier area was adopted and the filling ratio was 50%, obvious energy saving effects were achieved as aeration rate driving for the moving of the carriers was reduced more than 15%.
