Explore field-proven configurations engineered for produced water separation, high-salinity recovery, fracturing flowback reinjection, and process reclamation.
Transitioning from basic disposal well injection to hyper-saline resource mining and circular zero-liquid-discharge (ZLD) paradigms.
Traditional gravitational separation (API separators, skim tanks) combined with Induced Gas Flotation (IGF) and hydrocyclones. While capable of mitigating free hydrocarbons down to ~20–30 mg/L, these legacy methodologies fail to tackle sub-micron emulsion matrices, dissolved light hydrocarbons, and high organic fractions present in modern tight gas and unconventional oil reserves.
Adoption of Walnut Shell Filters (WSF), ceramic ultrafiltration (UF), and cold lime-soda softening combined with weak acid cation (WAC) exchanges. Essential for precipitating divalent scaling cations (Ca²⁺, Mg²⁺, Ba²⁺, Sr²⁺) and silicate matrices, safeguarding downstream high-pressure membrane layers from catastrophic irreversible fouling and mineral scaling.
The contemporary benchmark incorporates Disc Tube Reverse Osmosis (DTRO), Osmosis-Assisted Reverse Osmosis (OARO), and Mechanical Vapor Recompression (MVR). This enables over 95% volumetric water recovery with concentrate streams exceeding 180,000–220,000 mg/L Total Dissolved Solids (TDS), yielding boiler-feed condensate and crystallizing commercial-grade industrial salts.
How Chinese industrial fabricators satisfy rigorous international CAPEX/OPEX constraints and environmental mandates across the Americas, GCC, Central Asia, and Southeast Asia.
Global operators in regions such as the Permian Basin, GCC, and Caspian Sea demand skid systems with IP66/NEMA 4X certifications, Super Duplex Stainless Steel (2507) metallurgy, explosion-proof ATEX/IECEx Zone 1/2 compliance, and automated thermal self-regulation suitable for ambient limits between -30°C and +55°C.
Traditional site-built wastewater operations impose exorbitant EPC labor costs. Modern procurement favors pre-commissioned, containerized ISO skids. Factory Acceptance Testing (FAT) allows Chinese manufacturers to deliver operational plug-and-play modules capable of on-site water commissioning in under 15 days.
With operational margins constantly constrained by hydrocarbon pricing, global engineering teams demand energy recovery devices (ERDs) on high-pressure membrane stages, intelligent antiscalant dosers, and open-channel disc-tube membranes that reduce manual chemical CIP cleaning cycles by more than 40%.
Unconventional hydraulic fracturing requires tight quality standards: reinjection water must reach Oil in Water ≤ 5 mg/L, Total Suspended Solids (TSS) ≤ 1 mg/L, and micron ratings < 0.5 μm to protect shale formation porosity and prevent bacterial souring (SRB) deep downhole.
A multi-barrier membrane and thermal sequence delivering zero-fouling continuous operation across severe salinity regimes.
Dual-cell hydrocyclone cluster stripping gross solids (>50μm) and free hydrocarbons. Followed by an Induced Gas Flotation (IGF) unit with micro-bubble sparging to reduce hydrocarbons below 20 mg/L.
Automated lime-soda reaction precipitators strip soluble silica, barium, and calcium. Inorganic SiC ceramic membrane ultrafiltration filters out sub-micron flocs and emulsified droplet fractions with zero oil fouling.
Disc Tube Reverse Osmosis modules handling osmotic pressures up to 120 bar. Open-channel hydrodynamic profile prevents foulant cake layer formation, concentrating feed brine up to 140,000 mg/L TDS.
Patented Osmosis-Assisted Reverse Osmosis (OARO) membranes utilize low-salinity draw streams to suppress hydraulic resistance, elevating the brine concentration boundary past 200,000 mg/L TDS without thermal load.
Titanium Gr.2 / Inconel 625 falling-film evaporators compress secondary steam mechanically. Cuts thermal energy consumption down to ≤35 kWh/m³, yielding clean distillate water (<50 μS/cm).
Forced-circulation crystallization drying remaining mother liquor into solid sodium chloride / sodium sulfate salts. Solids are automatically dewatered via push centrifuges, concluding full ZLD compliance.
Mitigating cross-border operational vulnerabilities with factory-direct lifecycle integration.
All skids, membrane housings, and heat exchangers conform with international codes including ASME Section VIII Div 1, CE-PED (Pressure Equipment Directive), and National Board registration. Full material traceability records, weld X-ray radiographic testing (RT), and hydro-test certificates accompany every shipment.
Factory-integrated PLC systems (Siemens S7-1500 / Allen-Bradley ControlLogix) with secure cloud telemetry allow engineers to remotely track trans-membrane differential pressures (TMP), conductivity spikes, and flow fluctuations, maintaining continuous unassisted operation in remote oilfield pads.
Through our dedicated Global Service distribution hub, standard wear components—including replacement DTRO membrane disc stacks, mechanical pump seals, proportional dosing heads, and cartridge safety filters—are dispatched via expedited air logistics to minimize unscheduled field shutdown events.
Explore heavy-duty water treatment skids, high-pressure brine modules, and specialized industrial equipment directly manufactured in China.
In-depth responses resolving typical design bottlenecks, sizing queries, and operational parameters.
Our engineering department requires a comprehensive chemical characterization covering: (1) Total Dissolved Solids (TDS) and individual ion speciation (Ca²⁺, Mg²⁺, Ba²⁺, Sr²⁺, Na⁺, Cl⁻, SO₄²⁻, and reactive SiO₂); (2) Hydrocarbon content, distinguishing free hydrocarbons from dissolved fractions (BTEX) and Total Organic Carbon (TOC); (3) Physical indicators including Silt Density Index (SDI₁₅), Total Suspended Solids (TSS), turbidity, and operating feed temperature range; and (4) Site constraints such as available electrical supply (voltage/frequency), physical footprint limitations, and target discharge or reinjection requirements.
Spiral-wound membranes employ feed spacers that create stagnant flow areas prone to particulate bridging and biofouling. In contrast, DTRO utilizes an open-channel hydrodynamic geometry where fluid passes across octagonal hydraulic disc flow paths under high turbulence. This induces continuous self-cleaning shear forces across the membrane cushion surface, minimizing concentration polarization and enabling DTRO to process waters with Turbidity > 15 NTU and Oil > 10 mg/L without catastrophic clogging.
Yes. Our multi-stage treatment skids systematically combine coalescing oil removal, chemical softening, and specialized DTRO modules. Treated permeate streams routinely achieve Residual Oil ≤ 5 mg/L, Total Suspended Solids ≤ 1 mg/L, and particle ratings below 0.5 microns. This fully safeguards target injection horizons against particle blockages, while automated biocidal dosage halts microbial induced corrosion (MIC).
Conventional RO is thermodynamically limited to ~70,000–85,000 mg/L TDS because standard operating pressures cannot exceed membrane burst thresholds (~80–120 bar). OARO utilizes a counter-current draw solution on the permeate side of an engineered semi-permeable membrane. This lowers the net driving osmotic pressure differential across the barrier, enabling membrane concentration to reach 180,000–220,000 mg/L TDS. This substantially reduces the size and thermal operating cost of downstream MVR crystallizers by up to 45%.
Our manufacturing and engineering operations are certified under ISO 9001, ISO 14001, and ISO 45001, carrying CE certification for export machinery. High-salinity wetted parts utilize Super Duplex Stainless Steel (UNS S32750/2507), Titanium Grade 2, and rubber-lined or PVDF pipework. Full documentation packages include 3.1 Material Test Certificates (EN 10204), WPS/PQR weld qualification logs, NDT radiographic reports, Factory Acceptance Test (FAT) sign-offs, and complete electrical schematics.
