Above Ground Oil Water Separators (ECOS)

The oil separation chamber contains HD Q-PAC Coalescing Media containing a minimum of 132 square feet per cubic foot of effective coalescing surface area. The medias needle like elements (plates) are placed at 90 degrees to the horizontal or longitudinal axis of the separator. Spacing between these elements are spaced 3/16″ apart for the removal of a minimum of 99.9% of free droplets 40 micron in size or greater. The elements are positioned to create an angle of repose of 90 degrees to facilitate the removal of solids that may tend to build up on the coalescing surfaces, which would increase velocities to the point of discharging an unacceptable design flow rate shall be maintained throughout the separator packed bed including entrance and exit so as to prevent re-entrainment of oils with water. Flow, through the polypropylene coalescing media, is a crossflow perpendicular to the vertical media elements such that all 132 square feet/cubic foot of coalescing media surfaces point upwards, so as not to be available for contact with the crossflowing oily water. The media shall has a minimum void of 87% void volume to facilitate sludge and dirt particles as they fall off the vertical elements and settle in the sludge compartment. The media, when installed in crossflow oil water separator, meets US EPA Method 413.2 and also European Standard 858-1 for oil water separators.
