Point source runoff (floor drains) and non point source stormwater runoff from industrial areas (gas stations and other fueling facilities, maintenance facilities, ...) contains significant loads of sediments and oil. ecoSep® is the only high efficiency oil water separator providing independent (full size) testing certificates for each single model size, ensuring proper oil water separation and capture of sediments based on physical principles. The ecoSep® coalescing oil water separator exceeds the European Standards (EN858 and DIN 1999) for the separation of free non-emulsified oil from water (5ppm separation ratios). ecoSep® makes optimum use of three consecutive purification steps: Sedimentation, gravity oil water separation and final effluent polishing in the residual oil coalescing media. The accumulated oil is continuously being removed with a patented automatic oil draw-off device, thus saving disposal cost and avoiding emulsification.
