OIL / WATER SEPARATION

COMPANY CONFIDENTIAL

Approximately 706 million gallons of waste oil enter the ocean every year, with over half coming from land drainage and waste disposal.

Offshore drilling and production operations and spills or leaks from ships or tankers typically contribute less than 60 million gallons every year.

Routine maintenance of ships (140 million gallons/year), hydrocarbon particles from onshore air pollution (95 million gallons/year), and natural seepage from the sea fl oor (55 million gallons/year).

20-40% of oil evaporates, and the rest emulsifi es in the water forming a brown / black mousse; heavier parts of the oil sink, and some of the oil biodegrades eventually.

OIL IN WATER

TECHNOLOGIES TO SEPARATE OIL FROM WATER

Floating oil can be removed by oil skimmers, and in the ocean, fl oating oil spills have been contained by booms and skimmed off the water surface; rough ocean surface can make oil skimming very diffi cult; skimming only removes non-emulsifi ed oil.

Emulsifi ed oil can be removed using hydrophobic foams, but their capacity is limited, typically 10-30 times the foam weight. Further, the oil is removed by physically squeezing the foam, which results in mechanical degradation of foam material after a few cycles.

Ultra-fi ltration membranes have been used in oil-water separation, but they are expensive to buy and operate; fouling of membranes results in performance degradation.

APPLICATIONS OF OIL ERASERA Simple, cost-effective technology to separate oil from water.

WATER TREATMENT:Reticulated Oil Eraser foam can clean wastewater and retention ponds at a fraction of the cost.

CONTAINMENT:In addition to surface booms, Oil Eraser subsurface nets can be used as barriers to prevent spills from damaging beaches and wetlands.

PREVENTION:Use Oil Eraser foam as a fi rst line of defense against industrial pollution – containing the leak before it becomes an environ-mental hazard.

APPLICATIONS OF OIL ERASER

RECLAMATION:Captured oil can be extracted and Oil Eraser foam can be re-used indefi nitely– our process does not involve wringing, squeezing or otherwise damaging the foam.

CLEANUP:Oil Eraser even works on emulsifi ed oils – without introducing detergents to the environment.

FILTRATION:Oil Eraser can be used as a fi lter in waste pipes to collect petroleum waste products including oil, diesel, chlorobenzene and more.

APPLICATIONS OF OIL ERASER

The most challenging part of oceanic cleanup is subsurface oil – what looks like a brown cloud, emulsifi ed by wind and waves. Oil Eraser, suspended in plastic cages, forms a barrier, containing this hazard. Water passes through but petrochemicals are captured by the foam.

Neutrally bouyant cages trap underwater oil.

APPLICATIONS OF OIL ERASER

APPLICATIONS OF OIL ERASERIt’s not a foam ... it’s any foam.

APPLICATIONS OF OIL ERASERReclamation process saves water, oil, and foam

No wringing, squeezing or spindling. Oil Eraser uses a proprietary eco-friendly solvent to release and reclaim captured oil. Because this process minimizes mechanical wear, Oil Eraser can be re-used indefi nitely.
