WATERTECTONICS

The ecoLine B® is an oil water separator that far exceeds strict European standards (EN858) for performance (less than 5ppm of free oil) as well as current US regulatory requirements. Independent test certificates document the system’s ability to provide clean water that exceeds today‘s environmental standards. In addition, this separator is designed to meet stringent future environmental discharge compliance guidelines with little or no modification to the system.

The oil water separator is designed to separate non-emulsified light liquids and 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 process involving gravity separation and coalescing media elements, produces high removal efficiencies.

Purification Step 1: Gravity Separation

An optional upstream grit chamber removes solids from the influent, thus ensuring unimpeded functioning of the oil separator. The grit chamber (the first concrete tank of a standard two-tank design) also compensates for influent temperature fluctuations and influent oil concentration influxes. The separation of light liquids is initialized in the grit chamber.

Purification Step 2: Enhanced Coalescing Media

In the residual oil media, fine droplets (too small to be separated by gravity alone) are accumulated into bigger particles that rise to the surface. This enhanced coalescing media is made of durable netlike, soft polyurethane foam. The media cartridge is easy to remove and reinstall once it is rinsed with a garden hose. The outlet structure features a venting pipe that provides an effluent sampling port. The separated water exiting the system has a residual contamination of free petroleum content of less than 5 ppm.

Spill Control

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

Key Features

The ecoLine B® offers a full range of below ground oil water separators from 50gpm (3l/s) to 320gpm (20l/s). Grit chambers are sized according to the particular application.
