Combining heavy-industry metallurgy, automated skid integration, and mature precision membrane manufacturing, Chinese engineering delivers superior capital efficiency without compromising operational resilience.
Integrated Supply Chain
From corrosion-resistant Super Duplex (2507) and Titanium alloys to high-pressure composite pressure vessels, Chinese industrial infrastructure allows end-to-end component procurement with 35% shorter lead times.
Superior CAPEX/OPEX Ratio
By leveraging standardized modular design and in-house DTRO/STRO membrane manufacturing, global engineering EPCs realize 30-45% capital savings compared to North American and European equivalents.
Stringent Factory FAT Protocol
Skids are fully assembled, hydro-tested, wired, and program-verified in our Shanghai factory under ISO 9001, ISO 14001, and ISO 45001 standards, minimizing costly on-site hot work and troubleshooting delays.
Macro Trends Transforming Oilfield Produced Water Treatment
The global upstream extraction landscape is moving from basic disposal wells to closed-loop water sustainability, driven by strict regulatory ceilings and regional freshwater scarcity.
Shift from SWD to Closed-Loop Reuse
Disposal through deep well injection (SWD) faces regulatory quotas and seismic concerns globally. Energy majors now prioritize containerized membrane skids to treat fracturing flowback for immediate cross-well reinjection.
High-Pressure Membrane Concentration
Standard spiral-wound membranes fail under heavy hydrocarbons and scaling salts. Open-channel Disc Tube Reverse Osmosis (DTRO) operating at pressures up to 160 bar has emerged as the global benchmark for concentrating brine without rapid fouling.
Remote SCADA & Unmanned Skids
With production sites expanding in remote deserts and sub-zero tundra, modern produced water hardware requires automated chemical dosing, continuous conductivity tracking, and cloud-linked telemetry for unmanned field operation.
Field-Tested Engineering Across Extreme Operating Environments
Tongjie produced water units are purpose-built to maintain process stability under unpredictable feed waters, ambient temperature swings, and challenging field dynamics.
Desert Operations (Middle East & North Africa)
Designed for ambient heat up to 55°C. Equipped with dual-circuit HVAC systems, dust-sealed IP65 control panels, and specialized cooling jackets to prevent thermal degradation during high-recovery brine concentration.
Sub-Zero Drilling (Central Asia & Canada)
Fully insulated ISO containerized layouts equipped with internal glycol heat tracing, insulated double walls, and automated drain cycles to ensure uninterrupted winter operation without fluid freezing.
Tight Gas & Shale Stimulation Play
High variability in hydraulic fracturing flowback chemistry requires our rapid-cycling DAF (Dissolved Air Flotation) and catalytic softening stages to handle sudden spikes in Total Suspended Solids (TSS) and free oil.
Meeting the Demands of Global Oilfield Procurement Officers
Enterprise procurement teams choose Shanghai Tongjie because our manufacturing blueprints strictly adhere to international engineering standards, verified documentation, and life-cycle traceability.
Full Traceability Documentation
Complete project documentation packs, including EN 10204 3.1 material test certificates (MTRs), welding procedure specifications (WPS/PQR), and hydro-test charts provided for every assembly.
Seamless Industrial Automation
Standardized integration with Siemens S7-1500 or Allen-Bradley ControlLogix PLCs. Standard Modbus TCP, Profinet, and OPC-UA protocols for unified link-up with master refinery control systems.
Turnkey Container Mobility
Built into CSC-certified standard 20ft or 40ft sea containers. Equipment is structurally reinforced to endure rough off-road oilfield logistics, heavy crane lifts, and rapid site re-deployments.

How does Tongjie manage high levels of free and emulsified hydrocarbons in produced water?
Our integrated train utilizes a robust preliminary stage consisting of coalescence separation, Dissolved Air Flotation (DAF), and organo-clay adsorption. This process guarantees an inlet oil concentration of ≤5 mg/L before the feed touches the DTRO membranes, preventing organic foulant compaction on active membrane surfaces.
What is the maximum Total Dissolved Solids (TDS) limit for your DTRO systems?
Tongjie's high-pressure Disc Tube Reverse Osmosis modules are engineered to handle feed waters with salinities exceeding 120,000 mg/L TDS, operating at pressures up to 120 to 160 bar. Beyond this osmotic threshold, we integrate high-efficiency MVR (Mechanical Vapor Recompression) thermal crystallizers to achieve complete Zero Liquid Discharge (ZLD).
Can the system be mobilized for temporary exploration or multi-well campaigns?
Yes. All skids are engineered in standard ISO shipping container footprints with unified mechanical flanged connections and power hookups. Units can be relocated from pad to pad and commissioned within 15 days, drastically reducing infrastructure costs across temporary drilling campaigns.
What factory inspection milestones are provided prior to overseas dispatch?
Every skid undergoes a comprehensive Factory Acceptance Test (FAT) witnessed in-person or via high-definition live streaming. This includes radiographic weld examinations (NDT), hydrostatic pressure testing of pipework, insulation resistance checks, and wet performance testing with live automation simulation.
