Below Ground Plastic Oil Water SeparatorsMercer International, Inc. offers a line of competitively-priced below ground oil/water separators for flows up to 100 gpm. The tanks are constructed of corrosion-proof polyethylene and can be buried up to 30" below grade. The coalescer used in this separator is a new "coalescer ball technology" that attracts passing oil to the high surface area of a plurality of polypropylene balls. The coalescer balls are harnessed in removable netted bags. The bags are able to be removed and cleaned for reuse. This separator is ideal for gas stations, vehicle repair and maintenance garages, auto dealerships, airplane hangars and various wash rack applications. This solution has been the separator of choice by several statewide Departments of Transportation as the most cost effective way to remove oil from wash bay and wastewater and maintenance areas.
Below Ground Steel Oil Water SeparatorsMercer supplies a line of cylindrical below-ground, high-performance, oil/water separators from 50-5,000 gpm (10-1,000 m3/h). Separators are available in carbon steel (single and double wall), and a variety of high-grade coatings as well as FRP coatings.
A very popular choice for stormwater applications because pumps are not required. Most clients prefer our double wall construction for environmental reasons. Mercer outfits its units with leak detection and cathodic protection to protect the steel from corroding. Mercer builds below-ground cylindrical separators to the UL-58 and the UL-1746 standards as applicable, and also offers the STI-P3 corrosion protection package as endorsed by the Steel Tank Association
