Our oil-water separators are efficient and long-lasting

With a fiberglass underground tank at the heart of the design, a Xerxes oil-water separator incorporates unique refinements within the vessel to create a separator that removes free-floating oils and settleable sands from oil-water mixtures. A properly sized coalescer is designed to produce effluent quality acceptable to most regulatory requirements for water runoff.

Our oil-water separator is an excellent choice for parking lots, equipment washdown stations, vehicle repair garages, bulk fuel plants and truck stops. Adding a liquid-level monitoring system to gauge the oil level enhances the tank's performance.
