ABSTRACT:
The present invention provides a method of treating wastewater containing particulate matter and free oil, which method comprises removing free oil from the wastewater, passing the wastewater through a first filtration medium having an effective pore rating of about 200 .mu.m or less, subjecting the wastewater to dynamic filtration utilizing a second filtration medium having an effective pore rating of about 5 .mu.m or less, and contacting the wastewater with an adsorbent bed to form a purified water stream. The present invention also provides an apparatus which can be used to carry out the present inventive method.
