ecoLine-b Oil/Water Separator (เครื่องแยกน้ำมันออกจากน้ำ)

        It’s not just the ecoLine’s long maintenance intervals and low waste-disposal costs that make it such a good investment, but the fact that it is designed with future standards in mind. The ecoLine-b far exceeds the strict European standards (EN858) for performance (less than 5ppm of free oil) and far surpasses US requirements. The outstanding independent testing certi?cates demonstrate that ecoLine-b will provide clean water that exceeds today‘s environmental standards. ecoLine-b also allows for tighter, future
environmental discharge compliance guidelines to be met with little or no modi?cation to the system.

Stop throwing your money down the black hole of conventional oil/water separators. Put it where you can access it!
        All basic elements of the ecoLine-b system can be accessed from ground level. This minimizes con?ned entry requirements for routine cleaning and maintenance. Annual maintenance cost savings range from 30% to 50% lower than those of conventional separator systems. All internal stainless steel components can be factory installed in a standard precast concrete structure, which accelerates the installation of the ecoLine-b Oil/Water Separator. This provides the ?rst substantial cost savings in the form of reduced construction site labor. The ecoLine-b components can be designed in a modular way, which means these units can be installed into existing concrete tanks, even if the manholes are very small.

Working Principle.
The ecoLine-b oil/water separator is designed to separate non-emulsified  light liquids or low-water-soluble fluids with a specific gravity below 0.95 (gasoline, diesel, heating oils and other mineral oils) from effluent discharge. A two-step separation process, gravity separation and removal of small oil particles by coalescing media elements, produces high removal efficiencies.

Purification Step 1: Gravity Separation
The optional upstream grit chamber removes solids from the influent, thus ensuring unimpeded functioning of the oil separator itself. The grit trap is the first concrete tank of a standard two-tank design. The grit chamber also compensates for influent temperature fluctuations, influent oil concentration influxes and initializes the separation of light fluids.

Purification Step 2: Enhanced 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 enhanced coalescing media is made of durable 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 outlet structure features a venting pipe that provides an effluent sampling port. The separated water that leaves the ecoLine-b has a residual contamination of free petroleum content of less than 5 mg/liter.

Spill Control:
The automatic shut-off valve closes the outlet pipe when the maximum oil storage capacity is reached.
