Oil Refineries: Product Solution

FRC provided a solution for one of the longest continuously running refineries in the United States at a facility producing 11,000 bbl/d. The existing wastewater treatment system included a trickling filter upstream of a sand filter before sending the effluent to the local river. The sand filter was becoming overloaded with solids coming out of the trickling filter. FRC installed a DAF in front of the sand filter to remove the biosolids, allowing the sand filter to operate at a higher efficiency and the client to stay in compliance.

Design Data

FRC Solution

  • High-Rate DAF – Float the agglomerated biosolids, yielding effluent water with very low solid concentration that the sand filter is better able to handle.
