Fiberglass OWS - CSI-10

Our performance-proven fiberglass underground storage tank provides the base for our fiberglass underground oil/water separators.

Specifically designed to remove hydrocarbons with a specific gravity between 0.68 and 0.95, The CSI-10 model is design-tested and performance-rated. The model number (CSI-10) indicates an effluent quality of (10) parts per million.

Performance Features:
  • Removes free floating oils and settleable solids for oil/water mixtures to achieve an effluent quality not to exceed 10 ppm (mg/L) of free hydrocarbons.
  • Removes free oil droplets required to achieve 10 ppm effluent quality.
  • Includes a 30-year internal and external corrosion warranty.
  • Includes a 30-year structural warranty when installed according to CSI installation instructions.
  • Carries a one-year workmanship and materials warranty on internal separator components and coalescer plates, supports, etc.

All CSI Oil/Water Separator Tanks are designed and tested in accordance with the following criteria:

  • Stokes law
  • The API manual on disposal of refinery wastes
  • API bulletin no. 1630 first edition
  • API bulletin no. 421
  • UL-1316
  • ASTM D-4021
  • EPA Test Methods 413.1 & 413.2
  • US Coast Guard 46CFR 162.050
Coalescer Technology:

State-of-the-art enhanced oleophilic coalescers are intricately positioned to take advantage of this technically advanced design. Coalescer plates are removable for ease of maintenance.

This product requires a crane, (or when applicable a forklift) for offloading and placement.

This is also a product that may require local permitting.
