The site is a former oil recycling facility where the groundwater has been contaminated with a variety of organic and inorganic constituents. Accidental releases during the operation of the facility deposited approximately 29,000 gallons of used oil on the ground water surface.
All units operate at atmospheric pressure.
The emulsified oil then flows downward inside the outer shell of the unit and upward through a middle portion of the unit that contains plates that coalesce the oil. Final cleansing occurs as the remaining material flows upward through the center of the unitand then drains through the bed of oleophilic granules. The treated water than exits the system through Port C. For the SITE demonstration, the feed oil was recovered from the site and thinned with lighter petroleum products. The feedstream to the SFC System was generated by emulsifying the feed oil and ground water using an air powered inline blender. The effectiveness of the oleophilic granules were evaluated by comparing the TRPH concentration in the water before passing through the granules.
