Revolutionary Coalescing Media
for Oil Water Separators

HD Q-PAC® is increasingly recognized as the most efficient coalescing media yet developed for separation of oils from water containing suspended solids.

Why choose HD Q-PAC® over other coalescing media?

  1. 132 ft2/ft3 of effective coalescing surface. Removes over 99.9% of oil droplets 20 microns and larger. Meets both EPA Method 1664 Revision A and European Standard EN 858-1 (99.99% removal of free oil).

  2. Eliminate the need for 2nd stage polishing pads to attain affluent requirements. HD Q-PAC® can meet effluent requirements without high-maintenance polishing pads.

  3. The combination of a 90° angle of repose, with round smooth vertical surfaces and 87% void volume provide excellent self-cleaning and anti-plugging properties in oil water separators with heavy sludge, dirt and biological growth loadings.

  4. Polypropylene construction allows operating temperatures up to 212°F (100°C), which is significantly higher than conventional media.

  5. Optimized design allows oil to coat the entire surface of HD Q-PAC® media, unlike corrugated and inclined plate media in which much of the surface is unavailable for coalescing of rising oil droplets.
