Engineered Produced Water & High-Salinity Treatment Systems
Prefabricated, skid-mounted, and containerized industrial water units designed for high chemical resilience, extreme TDS variations, and continuous remote oilfield reinjection compliance.
The Mechanics of Produced Water: Addressing High-TDS, Hydrocarbon Emulsions & Scaling Kinetics
Oilfield produced water and fracturing flowback fluids present the most complex hydrodynamic matrix in industrial water treatment. Sourcing an Original Design Manufacturer (ODM) capable of handling volatile chemical kinetics requires rigorous engineering mastery.
De-Emulsification & Free Hydrocarbon Depletion
Fracturing flowback matrices contain emulsified crude, polyacrylamide friction reducers, and colloidal hydrocarbons. Conventional coalescing separators fail under shear-induced emulsification. Shanghai Tongjie incorporates dissolved gas flotation (DGF) integrated with micro-bubble electrolytic demulsification, driving free and dissolved oil concentrations down below 5 mg/L prior to membrane exposure.
- ✓ Residual Oil Content: ≤ 5 mg/L
- ✓ Colloidal Suspended Solids (SS): ≤ 1 mg/L
- ✓ Hydrocarbon recovery to upstream separators
Disc Tube Reverse Osmosis (DTRO) Dynamics
Standard spiral-wound reverse osmosis modules suffer catastrophic colloidal fouling when confronted with raw produced water. Tongjie’s open-channel DTRO modules feature octagonal hydraulic deflection discs that create high-frequency fluid vortexes. This hydrodynamic turbulence prevents laminar boundary layer concentration, operating safely up to 120–160 bar osmotic pressures.
- ✓ Max Operating Pressure: 90 to 160 bar
- ✓ Open flow channels prevent biological clogging
- ✓ Silt Density Index (SDI) tolerance > 5
Inorganic Scale Inhibition & Crystal Seeding
Severe saturation indices of Barium Sulfate (BaSO4), Strontium Sulfate (SrSO4), and Calcium Carbonate (CaCO3) lead to irreversible membrane scaling. Our turnkey process integrates stoichiometric lime-soda softening combined with seeded crystallization micro-reactors. Hardness ions are precipitated and dewatered, shielding secondary membrane and thermal stages.
- ✓ Total Hardness Reduction: > 98.5%
- ✓ Soluble Reactive Silica (SiO2) < 10 mg/L
- ✓ Sludge dewatering via integrated filter press

Produced Water Treatment Technology Roadmap (2025–2035)
From single-point compliance disposal to circular lithium extraction and net-zero thermal recovery. Review how Shanghai Tongjie guides international clients through evolving environmental mandates.
Hybrid DTRO + MVR ZLD
Integration of high-pressure tubular and disc-tube reverse osmosis with Mechanical Vapor Recompression (MVR). Shrinks liquid volume by 90% via membrane concentration before thermal crystallization, reducing thermal OPEX by over 60%.
Inorganic Ceramic MF/UF
Silicon Carbide (SiC) and Alumina tubular ceramic membranes capable of handling continuous 100% hydrocarbons, thermal shocks up to 80°C, and aggressive backwashing using aggressive solvents and ozonated fluids.
Forward Osmosis & EDR
Low-energy membrane brine concentration using engineered draw solutions and Electrodialysis Reversal (EDR). Achieves supersaturation beyond 220,000 mg/L TDS without requiring high-pressure mechanical pumps.
Circular Mineral Extraction
Transforming produced brine into revenue streams: Direct Lithium Extraction (DLE), Bromine harvest, and industrial-grade high-purity Sodium Chloride recovery, converting hazardous oilfield wastewater into commercial chemical stock.
Macro Industry Solutions: Tailored Process Trains for Demanding Environments
Every hydrocarbon basin and chemical cluster exhibits unique water chemistry. Tongjie engineers custom skid and container footprints according to localized salinity, biological loading, and regulatory discharge permits.
1. Unconventional Tight Gas & Shale Frac Flowback
Shale exploration requires massive fluid injection followed by rapid flowback surges loaded with friction reducers, heavy clays, and high salinity (up to 180,000 mg/L TDS). Our mobile trailer and containerized units deploy instantly to pad sites, conditioning water for immediate slickwater reuse and eliminating cross-country trucking logistics.
- ✓ Rapid field pad mobilization within 48 hours
- ✓ Automated friction reducer destruction via advanced electro-coagulation
- ✓ Closed-loop pad recycling efficiency ≥ 95%
2. Offshore Platforms & FPSO Marine Discharges
Deck real estate and weight are at an extreme premium on offshore production platforms. Tongjie manufactures ultra-compact Super Duplex 2507 and Titanium Gr. 2 membrane skids with ATEX / IECEx Zone 1 explosion-proof electrical controls. The treated overboard discharge reliably beats OSPAR and US EPA NPDES limits (< 15 ppm dispersed oil).
- ✓ Anti-corrosion metallurgies: 2507, Hastelloy C-276, Monel
- ✓ DNV/Lloyd’s-certified structural skid lifting frames
- ✓ Skid footprint reduction up to 40% vs. legacy gravity separators
3. Coal-to-Chemicals & Petrochemical ZLD
Coal gasification, ethylene cracking, and refinery effluent contain polycyclic aromatic hydrocarbons (PAH), cyanides, and high silica concentrations. Tongjie delivers three-stage treatment: biological nitrification/denitrification, high-efficiency reverse osmosis (HERO), and multi-effect vacuum crystallization yielding dry, transportable salt cakes.
- ✓ Complete Zero Liquid Discharge (ZLD) permit compliance
- ✓ High-purity crystalline salt separation (Na2SO4 / NaCl)
- ✓ Permeate recycling to boiler feedwater and cooling towers
4. Enhanced Oil Recovery (EOR) Polymer Flooding
Produced fluids from tertiary recovery contain high concentrations of partially hydrolyzed polyacrylamide (HPAM) that blind normal clarification filters. Tongjie combines catalytic ozone oxidation with disc-tube membrane arrays, cleaving polymer chains and preventing flux degradation under long-term operational regimes.
- ✓ Continuous polymer viscosity reduction
- ✓ Stable membrane flux across 3,000+ hours of continuous runs
- ✓ Subsurface formation protection against pore plugging
