Mercer International, Inc. is a manufacturer of high efficiency oil/water/solids separators of all sizes: above and below ground, and existing upgrades. They offer patented coalescer technology with true field-adjustable plate spacing for high efficiency. All oil/water separators are not created equal. Compromise has marked ordinary designs in the past decade. Separators designed to be efficient, require extremely high maintenance. Conversely, separators designed for low maintenance greatly sacrifice performance, leaving you with ordinary compromised results. Mercer International brings you both high efficiency and low maintenance--plus the versatility to field customize to suit your particular application. Our extraordinary design achieves extraordinary results. The Compliance Master design features the Multi-Pack coalescer that allows field adjustment to obtain the highest possible efficiency with the lowest practical maintenance frequency. Mercer supplies rectangular, above and below ground, and cylindrical direct-burial units of all sizes. Custom design separators, per our customer's requirements, for both process & wastewater flows are available. Upgrading existing steel, concrete and API separators with our Multi-Pack is available as well.
