International Production Specialists is the exclusive U.S. importer of the world-famous CURATOR Petrol Separator, which is made in Germany by Passavant Werks, A.G. The separator dominates the European market, where every parking lot and service station must have one. The first CURATOR model was produced more than 50 years ago and its engineering, design and practicality have withstood the multiplicity of demands placed upon it over that long period of time.

CURATOR Petrol Separators are gravity-type oil-water separators that take advantage of the differences in the specific gravities of water, oil or gasoline to achieve separators effectively and economically.

Water may contain oil in three major forms: "free oil," "emulsified oil," or "dissolved oil." Gravity-type separators will not separate emulsified or dissolved oil from water. Separation when those conditions exist requires other technology.

A gravity separator has a chamber that is designed to provide flow conditions sufficiently quiescent so that globules of free oil rise to the surface of the water and form a separate oil mass that can be removed mechanically.

The "rise rate" of oil globules (their vertical velocity) is the speed at which oil particles move toward the separator surface because of the difference in densities of oil and water. The closer the density of the oil or the grease is to that of water, the longer it takes for separation to occur. Here is a general guide:

The CURATOR Petrol Separator I.P.S. offers is designed to have a rise rate of oil globules that is equal to or greater than the surface-loading rate. The CURATOR Petrol Separator is engineered to approach the ideal design of a separator that has no short circuiting turbulence or eddies. As a result, the ultimate in gravity separation can be experienced with efficiencies and size.

The CURATOR Separator has been tested and approved by two independent organizations: The Bavarian Material Test Institute and Milwaukee School of Engineering. Both Institutions indicated the separators passed the German DIN 1999 standards (analogous to the American ASTM Standards) for petrol separators. Separators are tested to recover pollutants at the design flow rate. Effluent wastewater contained no more than 10 parts per million of oil when the CURATOR passed the test. Coalescing filters are also available.

SLUDGE TRAPS

To assure affective operation, wastewater flowing in must pass through a sludge trap prior to entering the separator. (This is also required in the German DIN 1999 standards.) In the sludge trap, wastewater is slowed, causing the heavier pollutants to settle out at the bottom of the sludge trap. The steel-fabricated sludge trap may be rectangular or cylindrical. A rectangular unit's dimensions shall be 40" high, 40" wide and 96" long with approximate sludge trap capacity of 700 gallons. (Size may vary where special installation restrictions are present.) A cylindrical unit's dimensions shall be 64" x 72" with approximate sludge trap capacity of 1,000 gallons.
