ecoStop's Working Principle

The Ecostop Spill
Control System is designed to control spills at petroleum storage or
fueling facilities. A spill situation shuts down Ecostop’s
closure valve, preventing the discharge of free oil to municipal sewers
or direct discharge outfalls. Ecostop maintains the spill on site where it can be contained either below grade (i.e. an underground storage tank or a large diameter pipe) or in an above grade, diked area. The capacities of this upstream storage reservoir should be large enough to accommodate typical amounts of a tank truck oil-spill (with an additional capacity, safety factor). The downstream Ecostop tank is equipped with Ecostop’s automatic shut-off valve (patent pending). This float actuated closure device stops the flow through the system when the maximum oil storage capacity or a certain liquid level in the Ecostop chamber is reached. In its closed position, the valve is watertight up to 0.5 bar (5m water column). The Ecostop detects spills automatically and therefore eliminates the most common failures in traditional spill control systems, human error. In the event of a minor petroleum build-up or a catastrophic type spill, changes in the liquid levels can be monitored by accurate and reliable liquid level sensor alarms . |
Installation |
|
 |
The system is
installed in-line and downstream from any segregated petroleum
containment drainage area treating runoff.
Ecostop comes pre-installed in a standard precast concrete manhole or in an Ecosep Oil/Water Separator. Ecostop can be retrofitted to an existing drainage system.
