Shanghai Tongjie Environmental Protection's oilfield produced water treatment system is specifically designed for oilfields in the Middle East, Kazakhstan, Xinjiang, and other regions. It employs a full-process technology comprising "pre-treatment (oil removal/gas flotation) + softening + ultrafiltration + DTRO high-pressure reverse osmosis + concentrate concentration." The influent contains ≤5000 ppm oil and ≤150,000 ppm TDS; the treated reinjected water meets standards (oil content ≤5 mg/L, suspended solids ≤1 mg/L), achieving zero discharge and reuse of fracturing discharge fluid. The system features containerized modular design with factory prefabrication and commissioning, enabling on-site operation within 15 days.

Oilfield produced water: Middle East/Kazakhstan oilfield produced water reinjection
Fracking discharge fluid: Zero-emission shale oil/shale gas fracturing fluids with reuse capabilities
Drilling Wastewater: Advanced Treatment of Drilling Mud Water and Well Wash Water
Offshore Platform: Platform oil-contaminated wastewater and produced water purification.
A: Through multi-stage air flotation combined with coalescence oil removal, the oil concentration is reduced from 5000 ppm to ≤5 mg/L, ensuring stable compliance with standards.
A: It withstands temperatures up to 55°C and down to -30°C, features dust and sand resistance, and is explosion-proof, making it ideal for extreme oilfield conditions.
A: With fully automatic operation, remote monitoring, and fault early warning capabilities, it enables unmanned operation, significantly reducing maintenance costs.
A: With chemical softening, anti-fouling membrane, and online cleaning, the scaling risk is reduced by 80%, ensuring long-term stable operation.
A: Due to the containerized skid-mounted design and factory pre-commissioning, the system can be fully operational on-site within 15 days of arrival.
A: Yes, our modular approach allows for parallel configuration, supporting capacities from 100 up to 5000 tons per day or more based on specific project requirements.
