Performance of SIDMBR for Emulsified Oil Wastewater Treatment

Abstract:

The Sequencing Inclined Dynamic Membrane Biological Reactor (SIDMBR) was investigated on a pilot scale for 60 days of emulsified oil wastewater treatment at zero excess sludge discharge. Results indicate that at hydraulic retention time of 24 h, the average removals of chemical oxygen demand (COD), ammonia nitrogen and oil are 66.83, 64.2 and 70.8% in 1~60 days, respectively. The membrane flux, biofilm quantity, and extracellular polymeric substances (EPS) content begin to change after 20th, which indicate that membrane fouling has occurred.
