Abstract:

The influence of imposed flux and aeration rates on membrane fouling in a submerged membrane bioreactor was studied. The experiments were conducted at four imposed fluxes and three aeration rates. The effect of flux on the reduction of membrane fouling was much higher than that caused by aeration rate. A lower flux of 20L/m2h produced 75 times more water than a higher flux of 40L/m2h with an aeration rate of 2 L/min. Low flux showed slightly higher removal of NH4-N and 93-96% removal of dissolved organic matter and chemical oxygen demand. Imposed flux also had a significant effect on the composition of organics present in the soluble microbial product (SMP) and extracellular polymeric substances (EPS). At a higher flux, both SMP and EPS had organics of high molecular weight (MW) of around 48kDa as well as lower MW organics below 200Da. © 2012.
