*Actual capacity - 870 Gallons
**Emergency oil spill capacity is 80% of tank volume based on no accumulated oil in vessel at time of spill.
CSI Oil/Water Separators are designed in accordance with Stokes Law, API 1630 and API 421, for the gravity separation of free oils and settleable solids from water, for intermittent and variable flows of oil/water combinations up to 20% oil concentration.
