Here are some of the most important process items we look at initially:

Flow Rate (design and maximum):

Oil inlet concentration: 

Temperature range of water (especially low point): 

Specific Gravity of oil at design temperature:

Viscosity of carrier fluid in centipoise at design temperature: 

Suspended solids concentration in wastewater (mg/l): 

Allowable oil concentration and TSS limits in effluent (mg/l):

The contaminants we see in today’s frac/flow back and produced water streams are quite varied, and leave producers and oil field servicing companies battling with a constantly changing stream of clay, dirt, metals, and chemicals along with the hydrocarbons. As such, the primary treatment of these diverse streams of wastewater requires a separator technology that provides for the removal of solids as well as the extraction of oils. The ability to efficiently remove hydrocarbons with various amounts of solids makes Mercer International the leading provider of primary oil water separation equipment to the O&G sector.

Mercer International provides above-ground separators known for efficiency and low maintenance. These separators can be customized on-site for specific applications, achieving outstanding results with our Compliance Master™ design featuring the Multi-Pack™ coalescer. This coalescer allows field adjustments for maximum efficiency and minimal maintenance. Unlike cheap plastic and steel coalescers that clog easily and require frequent replacement, This  Multi-Pack coalescer is easy to clean and lasts throughout the separator's life.
