ecoTop® is a high efficiency above-grade separator contained in a portable stainless steel vessel designed to separate above grade oil and water. Ideal for variable location and low flow rate applications with no construction site labor and reduced maintenance costs, ecoTop® is more cost effective than most conventional separation systems.
ecoTop® superior removal efficiencies (5 ppm) are achieved via a two-step separation process consisting of gravity separation and final effluent polishing. The separated oil is automatically removed from the water surface and collected in an internal or external oil recipient.
Purification Step 1:
Gravity Separation The sediment and solids pre-treated run-off, is gravity fed or pumped (typically with a positive displacement or diaphragm type pump) to the gravity separator through a submerged inlet pipe.
The separation process relies on the fact, that light fluids have a lower specific gravity than water and thus float on the water surface.
Purification Step 2:
Coalescing Media In the residual oil media, fine droplets, that are too small to be separated by gravity alone are accumulated into bigger drops that rise to the surface. This coalescing media is made of reticular (i.e. "net-like") soft polyurethane foam. The media-cartridge is very easy to lift out and reinstall once it is cleaned/rinsed with a garden hose. The separated water that leaves the ecoTop® has a residual contamination of free petroleum content to less than 5 ppm.
Applications
ecoTop® is used in the following areas:
- Transportation
- Gasoline stations
- Car wash and repair workshops
- Industrial process waste water
- Oil production, oil-removal plants
- Reconditioning of cooling water
- Treatment of waste water from oil-removal plants
- Mobile cleaning of oil-contaminated ground water
