Above Ground Oil Water Separators Over 1,000 gpm (225 m3/h)

Most separators designed for high efficiency require very high maintenance to obtain excellent effluent results. Conversely, separators designed for low maintenance greatly sacrifice performance, leaving you with ordinary and compromised results. Mercer International has perfected the design required to consistently supply high efficiency and low maintenance--plus the ability to customize performance in the field. This extraordinary design, rooted in creating a better way to process solids, makes Mercer International the best "life cycle" value available.

Herring-Bone Design - This a critical design feature as separator units become large--even in our largest units, no coalescer plate is ever wider than 2 feet (entry view). By utilizing a short plate width the coalescer can have tighter plate gap settings (thereby supplying a more balanced height to length ratio) which offers higher efficiencies and less plugging. That means we can increase efficiency by tightening up the gaps to achieve better effluent performance--the reasonable height to length ratio of the plates help assure lower maintenance. In larger units many of our competitors coalescer plate lengths can end up being 8' long (while ours are 2'). Imagine solids having to travel that distance before being able to be processed out of the coalescer. The bigger the unit, the more our features multiply their usefulness.
