ODM Sea Water Into Fresh Water Factory & Suppliers
Pioneering turnkey seawater reverse osmosis (SWRO), high-salinity recovery, and membrane process engineering for global heavy industries, offshore platforms, and coastal municipalities.
Advanced Desalination & High-Salinity Water Treatment Systems
Factory-engineered skid-mounted and modular production units designed for high-efficiency marine and industrial salinity transformation.
Global Desalination Dynamics & Market Projections
Navigating freshwater scarcity through high-recovery membrane trains, energy recovery technologies, and sustainable brine lifecycle systems.
Specific Energy Reduction (SEC)
Modern SWRO plants have achieved a paradigm leap by driving energy consumption down from >8 kWh/m³ to below 2.8 kWh/m³. Utilizing pressure exchanger isobaric energy recovery devices (ERD) with efficiencies topping 98%, our ODM factory setups substantially diminish OPEX for intensive production environments.
Rapid Modularization & Containerization
Offshore exploration camps, remote coastal hubs, and islands increasingly demand decentralized containerized units over sprawling civil works. Prefabricated, plug-and-play shipping container SWRO units bypass extensive on-site installation timelines and provide water security within days of port delivery.
Digital Twins & AI-Driven Operation
By coupling SCADA networks with edge-computing algorithm arrays, modern sea water plants continually calibrate flux rates, anti-scalant dosing, and clean-in-place (CIP) trigger intervals against real-time variations in seawater temperature, turbidity, and seasonal biological blooms.
Enterprise Procurement Priorities for Global EPCs & Operators
How our Shanghai-engineered direct factory solutions fulfill rigorous international technical specifications, durability tests, and metallurgy standards.
Metallurgical Integrity
Seawater environments generate aggressive crevice and pitting corrosion. We configure high-pressure headers and wet manifolds using high-molybdenum Super Duplex 2507 (UNS S32750), 1.4410, and high-spec GRP/FRP housings to survive high salinity feed cycles.
Pretreatment Robustness
Membrane longevity is determined before the high-pressure pump. Our systems incorporate dual-media pressure filters (Anthracite-Quartz) supplemented by automatic backwash disk filters and Ultrafiltration (UF) skids to keep Silt Density Index (SDI15) safely below 3.0.
Tier-1 Component Sourcing
Global supply chain continuity is prioritized. System layouts embed premium membrane elements (DuPont FilmTec, Hydranautics), high-pressure multi-stage pumps (Danfoss, Grundfos, Cat Pumps), and world-standard instrumentation (Siemens, Schneider Electric).
Skid Modular Scalability
Designs utilize standardized modular footprints that enable linear capacity expansion. As municipal or refinery requirements scale from 500 m³/day to 25,000 m³/day, additional skids dock with shared pre- and post-treatment networks without operational disruption.
Integrated Engineering Blueprint: Full Lifecycle Macro Solutions
Bridging primary raw seawater harvesting, membrane separation, and subsequent brine valorization through Zero Liquid Discharge (ZLD).
Phase 1: Intake & Conditioning
Whether utilizing direct open-sea velocity caps or coastal beach wells, intake water receives biocide dosing, coagulant-assisted flocculation, DAF (Dissolved Air Flotation) clarification when handling red-tide conditions, and precise micron filtration safeguarding system osmotic balance.
Phase 2: High-Pressure Desalination
Primary SWRO blocks operating between 55 to 70 bar split the stream into high-quality potable or industrial filtrate (TDS < 300 ppm) and concentrated brine. Secondary high-pressure passes address stringent WHO limits on Boron (<0.5 mg/L) and Bromide ions for drinking security.
Phase 3: High Salinity & ZLD Brine Recovery
Reject brine (TDS ~65,000 to 75,000 ppm) is further channeled into Disc Tube Reverse Osmosis (DTRO) or Osmosis-Assisted RO (OARO), culminating in MVR (Mechanical Vapor Recompression) crystallizers to extract industrial-grade salts, completing a circular zero-waste process.
Next-Generation Desalination Technology Roadmap
Strategic technological developments driving our manufacturing engineering lines over the coming decade.
Biomimetic Aquaporin & Nanocomposite Membranes
Integrating synthetic protein water channels (aquaporins) and graphene-oxide functional layers within polyamide thin-film composite (TFC) chemistry to deliver 30% higher pure water flux at identical drive pressures.
Direct Renewable Hybridization
Engineered dynamic variable-frequency drives that match high-pressure pump output to fluctuating solar PV and offshore wind turbine profiles, eliminating battery bank inefficiencies in off-grid deployments.
Brine Mineral Mining & Rare Earth Extraction
Industrializing selective nanofiltration and electrodialysis metathesis (EDM) stages downstream of the SWRO unit to extract high-purity magnesium, lithium, and potassium directly from desalination discard streams.
Localized Support Framework & International Compliance
Bridging factory-floor manufacturing in Shanghai with rigorous regulatory readiness across the Middle East, Southeast Asia, Latin America, and Europe.
Stringent Global Certifications
Every skid is engineered under ISO 9001 Quality, ISO 14001 Environmental, and ISO 45001 Occupational Health systems. Full CE Machinery Directive (2006/42/EC) and Pressure Equipment Directive (PED 2014/68/EU) certifications guarantee immediate field approvals.
Field Commissioning & Factory FAT
Comprehensive Factory Acceptance Testing (FAT) in our specialized wet-testing facility validates flow rates, hydrostatic pressure boundaries, and electrical safety before shipment. We deploy bilingual process engineers globally for rapid on-site Saturation/SAT oversight.
Global Spare Parts Ecosystem
We maintain regional inventories of consumables, replacement membrane elements, high-pressure ceramic plungers, filter cartridges, and chemical reagents to ensure plant uptime never suffers from supply-chain interruptions.
Frequently Asked Engineering Questions (FAQ)
Clear technical insights on equipment sizing, operational expenditures, membrane life, and specialized customization capabilities.
What feed water testing data is mandatory for a preliminary plant design?
We require comprehensive Total Dissolved Solids (TDS), specific ion breakdown (Cl, Na, SO4, Ca, Mg, Ba, Sr, SiO2, B), water temperature minimum/maximum variances, Silt Density Index (SDI15) or turbidity (NTU), presence of free oil/grease, and biological activity parameters.
How do containerized systems handle extreme ambient conditions?
Our heavy-duty marine containers feature dual-layer polyisocyanurate thermal insulation, specialized high-tonnage HVAC systems engineered for 50°C+ ambient temperatures, explosion-proof electrical panels (ATEX/IECEx standards), and external anti-corrosive C5-M marine epoxy coating systems.
What is the expected operating lifetime of the SWRO membrane elements?
Under correct automated anti-scalant dosing, micro-filtration, and consistent SDI maintenance below 3.0, high-rejection SWRO elements deliver 3 to 5 years of steady service. Our automated Clean-In-Place (CIP) systems run predictive recovery cycles to protect membranes from scaling.
Can your facility provide full private-label ODM manufacturing for overseas brands?
Yes. Tongjie supports distributors, system integrators, and engineering firms globally with complete white-label and ODM manufacturing. This includes custom skid mechanical layouts, client-specific HMI branding and PLC logic, customized paint codes, and localized engineering drawings.
