Oilfield Sewage Treatment Equipment

Oilfield Sewage Treatment Equipment

Oilfield water-treatment equipment must be selected from representative inlet-water analysis and a clearly defined discharge, disposal or reuse target. Vance can configure separation, dosing, flotation, filtration and control stages as a modular package, subject to the agreed water data and test plan.

Effective management of produced water, drilling wastewater, and oilfield effluent streams is one of the most operationally and environmentally critical challenges facing upstream oil and gas operators worldwide. VANCE Oilfield Sewage Treatment Equipment provides a comprehensive, field-deployable solution for oilfield sewage treatment, delivering consistent, compliant effluent quality from the complex, high-volume wastewater streams generated throughout the full oilfield production lifecycle. Engineered as modular, skid-mounted or trailer-mounted produced water treatment equipment systems, VANCE oilfield wastewater treatment solutions integrate multiple proven treatment process technologies — including physical separation, chemical dosing, filtration, and disinfection — into a single, compact, and operationally robust treatment train designed for rapid field deployment, minimal operator intervention, and reliable long-term performance under the harsh environmental and operational conditions of remote oilfield production sites. The VANCE Oilfield Sewage Treatment Equipment platform addresses the industry’s pressing need to reduce freshwater consumption, achieve regulatory discharge compliance, and enable treated water reuse for drilling, fracturing, and dust suppression applications across global upstream oilfield operations.

Key Features

• Integrated multi-stage treatment process combining oil-water gravity separation, induced gas flotation (IGF), multimedia depth filtration, chemical coagulation and flocculation dosing, and ultraviolet or chemical disinfection within a single skid-mounted or trailer-mounted Oilfield Sewage Treatment Equipment package delivers consistent effluent quality across widely varying influent water chemistry and flow conditions encountered in oilfield produced water and wastewater treatment service.
• Modular skid and trailer-mounted system architecture enables rapid transport and deployment to remote oilfield locations without requiring permanent civil infrastructure, allowing operators to commission a fully operational oilfield sewage treatment system within hours of equipment arrival at the wellsite or production facility, minimizing project mobilization time and associated downtime costs.
• Automated PLC-based process control system with HMI touchscreen operator interface provides continuous monitoring and automatic adjustment of all critical treatment process parameters — including chemical dosing rates, filtration backwash cycles, flotation air injection rates, and effluent quality indicators — reducing the operator skill level requirement and ensuring consistent oilfield wastewater treatment performance throughout extended unattended operating periods.
• High-efficiency oil-water separator with corrugated parallel plate pack internals achieves rapid bulk oil removal from raw produced water and oilfield wastewater influent streams at high volumetric throughput rates, protecting downstream treatment process stages from oil overloading and extending the service life of filtration media and chemical dosing system components throughout the treatment campaign.
• Chemical coagulation and flocculation system with automatic variable-rate dosing pumps, chemical mixing and reaction chambers, and configurable chemical injection points accommodates the wide range of dissolved solids, suspended solids, hardness, and hydrocarbon contaminant concentrations found in produced water and oilfield sewage treatment influent streams from different geological formations and production reservoir types.
• Multimedia pressure filtration vessels with high-quality anthracite, sand, and garnet filter media layers provide reliable removal of suspended solids, residual oil droplets, and flocculated contaminant particles from the treatment stream ahead of final polishing and disinfection stages, achieving the low suspended solids effluent concentrations required for regulatory discharge compliance or water reuse in oilfield operations.
• Corrosion-resistant carbon steel or stainless steel vessel and piping construction with internal epoxy lining or hot-dip galvanizing as standard, combined with heavy-duty structural steel skid frames rated for long-distance road transport and repeated field relocation, ensures the mechanical integrity and long service life of the produced water treatment equipment under the demanding handling and environmental conditions of international oilfield deployments.
• Flexible effluent quality design basis accommodates site-specific regulatory discharge standards, reinjection quality specifications, and water reuse quality requirements — including standards for reuse in hydraulic fracturing operations, agricultural irrigation, or surface water discharge — enabling the VANCE Oilfield Sewage Treatment Equipment platform to be configured precisely to the compliance and operational requirements of each project.
• Integrated sludge management system with sludge collection sump, sludge thickening and dewatering provisions, and sludge holding tank manages the concentrated solid waste streams generated by the treatment process, reducing the volume and improving the handling characteristics of oilfield treatment residuals for compliant off-site disposal or further processing at the production facility.
• Full instrumentation package including influent and effluent flow meters, pressure gauges on all vessels and filter vessels, online oil-in-water analyzer, pH transmitter, turbidity sensor, and remote telemetry output enables comprehensive real-time treatment performance monitoring and supports integration with the production facility’s SCADA or remote monitoring systems for centralized operational oversight of all oilfield water management assets.
