About Oil Water Separators
Oil / water separators are designed to remove all free and dispersed non-emulsified oil and some settleable solids from waste streams. If emulsified or dissolved oils are present in the waste water additional downstream may be required. The principal function of the oil / water separator is to remove gross quantities of free oil before further treatment. In this capacity, the oil / water separator protects more sensitive downstream treatment processes from excessive amounts of oil.
There are a few applications where oil / water separators are the only end-of-pipe treatment provided to obtain effluent requirements. One example is in the petroleum industry, where the only effluent restrictions specified are for oil or suspended solids. In these cases, the wastewater in question consistently contains sufficiently low amounts of emulsified and and dissolved oils to meet effluent requirements after the free oil is removed.
Another example is a stream which is discharged to a publicly owned treatment works (POTW). The oil / water separator is used to ensure compliance with requirements for pretreatment of oil and grease.
It should be stressed that whenever an oil / water separator is considered for an application where it must stand alone, the amount of emulsified and dissolved oils in the wastewater stream must be properly quantified. The designer must also determine if any heavy metals are present in the wastewater. If any of these conditions are present in the wastewater stream they will not be removed by the oil / water separator and will effect the effluent test results.
It should also be noted that an oil / water separator must have sufficient space for storage of some settleable solids. The same process which causes the oil to rise and separate will cause solids to fall.
What Makes Hydro Quip's Oil Water Separators “Revolutionary”?
Why are Hydro Quip's Oil Water Separators revolutionary? The reason is that no other oil water separator exists that possesses all of the following traits:
- Meets EPA Method 413.2 and European Standard EN 858-1
- Non-plugging
- Very high surface area
- 99.99% removal of free and dispersed oil, 20 micron size or larger
- High flow rates

Advantages of HD Q-PAC® Media in Oil Water Separators
HD Q-PAC® has the following advantages when compared to traditional corrugated type and inclined plate type coalescing media used in oil water separators.
- 132 ft2/ft3 of effective coalescing surface. Removes over 99.9% of oil droplets 20 microns and larger. Meets both EPA Method 413.2 and European Standard EN 858-1 (99.99% removal of free oil).
- Eliminate the need for 2nd stage polishing pads to attain effluent requirements. HD Q-PAC® can meet effluent requirements without high-maintenance polishing pads.
- The combination of 90° angle of repose, with round smooth vertical surfaces and 87% void volume provide excellent self-cleaning and anti-plugging properties in oil water separators with heavy sludge, dirt and biological growth loadings.
- Polypropylene construction allows operating temperatures up to 212°F (100°C).
- Optimized design allows oil to coat the entire surface of HD Q-PAC® media, unlike corrugated and inclined plate media in which much of the surface is unavailable for coalescing of rising oil droplets.
