A case study of industrial MBR process for poultry slaughterhouse wastewater treatment

The wastewater discharged from the poultry slaughterhouse always contains high levels of chemical oxygen demand (COD) and biochemical oxygen demand (BOD) and thus, it requires proper treatment to minimize its negative impacts on the receiving water bodies. In this work, we presented a local case stu...

description The wastewater discharged from the poultry slaughterhouse always contains high levels of chemical oxygen demand (COD) and biochemical oxygen demand (BOD) and thus, it requires proper treatment to minimize its negative impacts on the receiving water bodies.

Over the 6-month monitoring period, our results showed that the permeate flow rate of the MBR process was relatively stable and only suffered from approximately 16% flux decline for the entire period with 8-h operation daily.
