Oil-Water Separators

Our oil-water separators are efficient and long-lasting

The Xerxes underground oil-water separator (OWS) provides an efficient, long-lasting solution for removing free-floating oils and settlable sands from oil-water mixtures in a variety of applications. Our tank is the perfect solution for managing water and effluent runoff in sites such as parking lots and equipment washdown stations. The coalescer technology in our oil-water separator removes oil droplets to a size of 20 microns or larger.

Customers can select the appropriate flow rate and spill capacity for their specific needs, making Xerxes tanks ideal for a variety of sites and applications, including vehicle repair garages, bulk fuel plants, truck stops and commercial parking lots. Performance of a Xerxes oil-water separator is enhanced with the addition of a liquid-level monitoring system to gauge the oil level. Our separators are available in UL-listed and ULC-listed models, making tank owners and project designers confident that the effluent performance data has been third-party validated.
