A more promising alternative for ,wastewater, remediation is the combination of the activated sludge treatment with membrane ,filtration, process. This technology, also known as membrane bioreactor (MBR), differs from CAS since a membrane module is used instead of the secondary clarifier to separate activated sludge from the final effluent ( Xing et al., 2000 ).

The particular ,wastewater, was characterized by oil and grease (O & G) concentrations as high as 6 g/L, COD of 51 g/L, BOD of 16 g/L and volatile fatty ,acid, (VFA) of 8.3 g/L. The use of a submerged membrane bioreactor for the treatment of industrial oil contaminated ,wastewater, was investigated using microfiltration hollow fiber membranes by [56] .
