WHY ABOVE GROUND

Engineered solutions for non-standard, high-consequence applications

Some wastewater challenges do not fit into predefined product families.

Mercer designs custom oil-water separators for applications involving temporary operations, extreme flows, unusual oil or solids behavior, emergency response, or site conditions that prevent standard installation.

These systems are not experimental.
They are engineered, tested, and deployed with intent.

Test for Free. Decide with Proof.

We test at no cost and tell you upfront whether Mercer’s solution will or will not deliver meaningful improvement.
If the data proves it works, we guarantee performance. If it doesn’t, you walk away informed.

Custom & Engineered Solutions

Mobile Oil-Water Separators

Portable separation for temporary or rapidly changing operations

Mercer’s mobile oil-water separators are trailer-mounted, skid-mounted, and containerized systems designed for temporary deployment, pilot testing, emergency response, or locations where permanent infrastructure is not feasible.

These systems allow operators mobility to collect from multiple points of contamination, or jump from one environmental emergency to another.

Best suited for:

  • Emergency spill response
  • Upstream oil field services companies
  • Turndown outage bypass for multiple locations

Turnkey Oil-Water Separation Systems

End-to-end engineered solutions with a single point of accountability

Mercer’s turnkey systems integrate separation equipment, automation, controls, pumps, and support infrastructure into a complete, engineered solution. These projects are managed from evaluation through commissioning, reducing risk for owners and engineers.

Best suited for:

  • Customers who can’t afford environmental issues
  • Complex wastewater streams
  • Facilities requiring guaranteed performance

Field-Assembled Oil-Water Separators

Large-scale systems assembled on site to meet extreme demands

For applications exceeding transport or fabrication limits, Mercer designs field-assembled oil-water separators built on site. These systems support very high flow rates or tough to access spots, and are configured through engineering review to match site-specific constraints.

Best suited for:

  • Very large oil field and refinning projects
  • Hard to reach locations in sub basements or hydroelectric dams
  • Sites requiring custom geometry or footprint

Frequently Asked Questions

Q.

Are custom systems more expensive than standard units?

A.

Not always. Custom systems are engineered to solve specific problems efficiently, often reducing long-term operating and maintenance costs.

Q.

Can custom systems be scaled or expanded later?

A.

Yes. Many custom systems are designed with modularity or future expansion in mind.

Q.

Do custom systems require testing?

A.

Yes. Mercer evaluates influent conditions and performance requirements before finalizing any custom design.
