What It Does

VACUUM COLLECTS OILY WATER AND WASTE OIL at its source through a network of customer-provided hard-piped collector stations and hoses, into a remote, centrally located, 105 gallon system vacuum tank. Compared to other liquid conveying methods, vacuum collection offers the following advantages:

Infinite collector station configurations.
Manual (valves at hose ends are most common) or mechanical flow activation and control.
Continuous or intermittent flow.
Simultaneous operation of multiple collector stations.
Dry lift heights to 25 feet.
Horizontal runs hundreds of feet away from vacuum source.
Minimum probability of accidental leakage to the environment.
Minimal undesirable liquid agitation.
No need for any additional pumps or equipment.

SEPARATES OIL FROM WATER by combining 4 routinely used physical technologies in 3 sequenced stages which progressively reduce oil in water concentrations. NOTE: Additional subsequent treatment and separation stages are possible/optional:

Stage	Type	Technology
1	Physical - Static	o Vacuum induced low grade dissolved air flotation o Differential specific gravity/quiescent separation
2	Physical - Dynamic	Oleophilic media contact entrapment
3	Physical - Dynamic	Pressure screening through conventional coalescer filter elements
4 (opt)	Physical/Chemical	Oil-selective media adsorption, ultrafiltration, etc

DISCHARGES WASTE OIL (almost water-free) into storage facility(s) for further use, resale, disposal, reclamation, or treatment.

DISCHARGES TREATED WATER (only slightly contaminated, typically 5 - 15 ppm oil if not chemically emulsified) directly to sanitary sewers (legal in most communities) or to storage facility(s) for further use, reclamation, or treatment.
