The wastewater will be also highly acidic and oily with Sulphate and Phosphate content that cause serious threat to environment and mostly the aquatic life. With the increasing demand on treating wastewater from edible oil processing units, membrane technology including ceramic membrane bioreactor and RO /NF combined process has been applied to treat edible oil processing wastewater.

Overall, the newly developed FO membranes can recover ∼80% of the water at a ,high, average water flux of 10.4 LMH using 1 M NaCl as draw solution from a 500 ppm oil–water emulsion containing a low salt ,concentration, of 0.5 g/L. This, in turn, demonstrates the potential of the FO membranes for ,oily wastewater, reclamation.

Usually phenolic wastewater with a mass concentration of 1000mg/L is called high-concentration phenol-containing wastewater, and this kind of wastewater must be recovered after treatment. The phenol-containing wastewater with a mass concentration of less than 1000 mg/L is called a low concentration phenol-containing wastewater.
