Oil / Water Separators

The Xerxes underground oil/water separators, which allow customers to select the appropriate flow rate and spill capacity for their specific needs, are simply one example of the company’s reputation for innovation. Xerxes was the first to make fiberglass underground tanks and separators with integrally constructed ribs, which dramatically increase the tanks’ robustness. Xerxes was also the first to make fiberglass underground doublewall storage tanks and to obtain the Underwriters Laboratories (UL) Subject 2215 listing. The added design flexibility Xerxes brings to its oil/water separators couldn’t have come at a better time.

Today, more and more regulations are in place to diminish the impact of oily water runoff on the environment. To address environmental and regulatory concerns, Xerxes offers an oil/water separator that is:

  • cost-effective
  • rustproof
  • lightweight
  • designed to meet customer site-specific needs
  • offered as a UL Subject 2215-listed option
  • made with unique vertical-tube coalescers
  • backed with a Xerxes limited warranty

Unique Coalescer for Superior Performance and Maintenance

At the heart of Xerxes' oil/water separator is a unique vertical-tube coalescer. The random tube matrix design provides laminar flow important to proper separation. Small oil droplets are attached to the polypropylene tube matrix because of its oil-attracting characteristics. Once attached, they provide additional surface area to the tubes while attracting other small oil droplets with their own inherent properties. This process combines oil droplets until they are large enough to rise to the surface to await periodic removal.

Please consult a Xerxes representative for more details on Xerxes' oil/water separators.
