Oil/Water Separators

99.99% Free Oil Removal

The Draygon CS-20-IP Clarifier/Separator will remove essentially 100% of all free and dispersed non-emulsified oil droplets larger than 20 microns in diameter with a specific gravity of .90 or less. The separator is designed for above grade installation and will be constructed of 12 gauge 304 stainless steel.

Our oil/water separators are an ideal adjunct to our evaporators when wastewater has a heavy oil component. Draygon Oil / Water Separators meet EPA Method 413.2 and European Standard EN 858-1 (99.99% Free Oil Removal).

Our Oil / Water Separators include a tank containing an inlet compartment, separation chamber, sludge chamber, and clean water outlet chamber.

Droplets are intercepted by the corrugated plates as the oil/water mixture flows through the separator, new droplets coalesce with retained droplets, making larger droplets. Enlarged droplets are released and rise to the surface to be decanted into a storage tank.

Stokes’ Law calculations, based on a flow of zero velocity, result in a Reynold’s number less than 500 to ensure optimum separation.

Unique Technology Cross-fluted design/internal intercon-necting channels for enhanced efficiencies in significantly smaller units. Droplets are intercepted by the corrugated plates as the oil/water mixture flows through the separator, new droplets coalesce with retained droplets, making larger droplets. Enlarged droplets are released and rise to the surface to be decanted into a storage tank. Stokes’ Law calculations, based on a flow of zero velocity, result in a Rey-nold’s number less than 500 to ensure optimum separation.
