The HD Q-PAC media has vastly superior properties compared to the traditional media used in oil-water separators. These properties result in a more efficient and effective separation than that attained by traditional coalescing media, for a variety of reasons.
In a typical oil-water separator with traditional media, incoming oily water slowly flows from the inlet through a media comprised of a series of parallel, inclined plates. As the oil droplets in the water coalesce with other oil droplets on the media surface, the oil droplets grow in size and travel up the plates to the water surface. This design, however, allows some water droplets to by-pass the plates and flow through the separator, requiring secondary polishing filters to achieve the required effluent characteristics. The shapes and configurations of tradition coalescing media also traps particles and sludge on the media itself, resulting in a sludge build-up and a reduction of effective flow through the separator.
The HD Q-PAC media provides improved performance in oil-water separators over traditional media due to the following properties:
– A larger amount of surface area per cubic foot of media allows for greater oil drop coalescence. HD Q-PAC media has 132 ft2/ft3 surface area for oil droplets to contact. Other typical coalescing media have about 48 ft2/ft3 to 68 ft2/ft3.
– A more efficient first step separation reduces the need for a second polishing step. HD Q-PAC media removes 99.9% of oil droplets 20 microns in size and larger. This meets EPA Method 1664 Revision A and European Standard EN 858-1.
– An open design eliminates trapping of particles and subsequent clogging of water channels. Oil water separators with HD Q-PAC media require fewer maintenance shut-downs and separates oil and water faster.
– Where higher-than-normal operating temperatures are required, HD Q-PAC media outperforms its competitors. HD Q-PAC media works effectively in temperatures up to 212°F, versus a maximum temperature of about 120°F for competing media.
