A Membrane-Aerated Bioreactor for Simulated Oilfield Wastewater Treatment

Abstract:

A membrane-aerated bioreactor (MABR) was developed for the wastewater treatment with simulated oilfield wastewater. Long-running experimental results showed that the removal percentages of oil and COD were 80-90% and 75-85% respectively and the concentration of NH4+-N was less than 2 mg/L, turbidity less than 50 NTU in the effluent. The results lay a good foundation for further research and development of MABR treatment process and technology. MABR has the technical feasibility for the oilfield wastewater treatment.
