Washington State Ferries, a company that operates on routes with tremendous environmental concern and legislation, recently refit one of its ferries, Nisqually, with a bio-enhanced Oil Water Separator solution from ECP Service Corp. The Washington State Department of Transportation operates one of the largest passenger and automobile ferry services in the world, with 29 vessels capable of generating between 2,000 to 3,000 gallons of oil water in the vessels' bilge each month. The company sought a solution that would reduce or eliminate disposal cost, improve oily water separator efficiency and create a more environmentally responsible operation.
