Oil-Water Separators

Our oil-water separators are efficient and long-lasting

The ZCL | 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 ZCL | 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 ZCL | 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.

100% Premium Resin and Glass (No Fillers)
ZCL | Xerxes tanks are constructed of 100% premium resin and glass. We use no fillers or recycled materials, which sets us apart from many tank options. We maintain our standard of excellence by performing verification tests on our resin and glass to ensure that only high-quality materials are used in the manufacturing process.
Corrosion Resistance Inside and Out
ZCL | Xerxes tanks are made of fiberglass, which means they are inherently resistant to corrosion. Because they are corrosion-resistant inside and out, you’ll have the peace of mind of choosing a tank that helps preserve and protect the environment. You’ll also enjoy a lower cost of ownership than with steel and concrete tanks, which corrode over time and require maintenance.
Flexible Design & Installation Options
ZCL | Xerxes fiberglass tanks come in a wide range of sizes and designs – along with numerous accessories and monitoring options – to meet a variety of site and regulatory requirements, for both underground and aboveground installations. Contact us today to discuss your next project.
