How does an oil water separator work?

Above Ground Clarifier Oil Water Separator Flow Process

  1. The oil/water/sludge mixture enters the oil water separator
  2. The heavier sludge and particulates fall out of the fluid and are captured in the sludge hopper
  3. The oil and water mixture with lighter particulates travels up the inclined plates
  4. The inclined plates start to separate the mixture. Some oil rises to the top of the separator and the remainder of the particulates slide back down to the sludge hopper.
  5. The remaining oil and water mixture then moves through the coalescing media packs where the majority of the smaller oil particles attach to the media and combine together to form larger oil particles.
  6. These larger oil particles become so buoyant that they release from the media and travel to the top of the separator.
  7. As the oil volume in the separator reaches a certain level, the oil is drained to through piping to an oil storage tank.
  8. The clean water continues over the weir to the clean water chamber where it goes through a final polishing pack and out to the sewer.
