Steam It — and Mercer Will Clean It
Mercer’s enhanced gravity separators pre-treat produced water heading to Saltwater Disposal (SWD) wells, protecting injection integrity, reducing downtime, and capturing valuable hydrocarbons before disposal.

INDUSTRY INSIGHT
Saltwater Disposal (SWD) facilities operate under intense pressure (in more ways than 1):
• Regulatory expectations are rising
• Injection pressures are climbing
• Water chemistry is becoming more complex
• OPEX and downtime can make or break profitability
Without effective pre-treatment, hydrocarbons and solids carried into the injection stream cause well fouling, pressure increases, pump strain, loss of injectivity, and unplanned maintenance, all of which can shut down operations and cost millions.
Mercer International’s Compliance Master™ separator with the Multi-Pack™ coalescer is engineered specifically to remove free oils, dispersed hydrocarbons, and settleable solids BEFORE they reach the injection well. Why put 1% oil down hole?
The result?
Cleaner water, lower injection pressure, extended well life, and recovered hydrocarbons that directly offset operational costs.
Mercer systems give SWD facility operators consistent, predictable performance, even with variable loads, high solids, paraffins, or surfactant-laden produced water.
ENERGY INDUSTRIES
Hydrocarbons and solids interfere with formation permeability. Effective pre-treatment keeps pressures stable and reduces pump wear.
Produced water chemistry changes daily: temperature, solids, chemicals, iron, organics, and oil content all fluctuate.
These compounds build up on pipes and injection equipment, costing operators time and money.
SWDs run 24/7. Equipment must match that uptime without requiring constant intervention.
Regulations continue tightening for disposal, spills, overflows, and hydrocarbon discharge from containment areas.
MERCER ADVANTAGE
Mercer’s enhanced gravity systems are designed to prevent the two biggest SWD profit killers: well fouling and unplanned downtime.
Key Design Features:
Handles heavy oil, light oil, paraffin, and solids without plugging, no corrugated or small-crevice media.
Wide-flow pathways and settleable solids zones reduce carry-over and protect injection equipment.
Delivers high-efficiency oil removal in a compact, above-grade or in-ground configuration.
Recovered hydrocarbons are returned to the operator, often covering system costs over time.
Oil skimming, alarms, and SCADA-ready monitoring reduce operator workload and improve safety.
Coatings and materials chosen for brines, high TDS, H2S exposure, and harsh water chemistries.
APPLICATION AREAS
Removing oil and solids prevents fines and organics from plugging the formation, maintaining lower, more stable injection pressure.
Yes. Mercer designs its internals to operate without clogging under paraffin or iron-rich conditions.
Absolutely, with superior performance in a smaller footprint and far less maintenance.
Frequency depends on solids loading, but far less than CPI or plate-style separators.
Yes. Oil-level alarms, auto-close valves, telemetry, and remote monitoring are available.
They are engineered to exceed the separation performance and hydraulic intent of API 421.
