Oily wastewaters are generated in many industrial processes, such as petroleum refining, petrochemical, food, leather and metal finishing. Fats, oils and greases (fog’s) present in these wastewaters have to be removed before the water can be reused in a closed-loop process or discharged into the sewer system or to surface waters.
However, chemically stabilized oil/water solutions should be managed in an appropriate manner. These solutions can be purified by means of membrane filtration.
