In this study, the aim was to observe organic removal performance from synthetic greywater in a fluidized membrane bioreactor using granulated activated carbon as fluidized media and to understand membrane fouling behavior aided by GAC. Prior to the application, the batch and column adsorption test were done to monitor adsorption behavior of GAC for greywater. Later, effect of GAC was observed varying different permeate fluxes and hydraulic retention times in a lab-scale fluidized bed membrane reactor. Fluidization of GAC reduced the membrane fouling caused by greywater effectively. However, organic removal alone with the PVDF membrane suggests the adsorptive effect by GAC on fouling mitigation was limited through the adsorption effect by GAC fluidization. Organic removal alone with the membrane found to increase organic removal efficiency with time due to the fouling layer on membrane surface acting as a secondary membrane. |
