Market Deep Dive
Chile's Industrial Landscape: Water Stress & Technology Vectors
A macroeconomic and hydro-geological overview of Chile's transition toward desalinated seawater and circular zero-discharge closed loops.
Severe Water Scarcity & Mining Hubs
The Norte Grande and Atacama regions of Chile contain the planet's driest biomes alongside its most copper- and lithium-rich operations. Groundwater extraction caps imposed by the Dirección General de Aguas (DGA) have forced EPCs and resource majors to deploy large-scale coastal SWRO desalination units, pumping treated permeate over 3,000 meters above sea level.
- Mandatory transition to desalinated seawater
- Energy recovery integrations for extreme pumping heads
- Heavy scaling prevention on high-sulfate source waters
Lithium Extraction & Salar Preservation
Under Chile's National Lithium Strategy (Estrategia Nacional del Litio), direct lithium extraction (DLE) and Osmotically Assisted Reverse Osmosis (OARO) must rapidly replace uninhibited solar evaporation ponds to protect the hydrologic equilibrium of the Salar de Atacama and Salar de Maricunga basins.
- High-pressure concentration up to 120-150 bar
- Direct boron and sulfate re-crystallization systems
- Permeate recovery exceeding 85% in brine cycles
Aggressive Regulatory Compliance
Chile's Decreto Supremo 90 (DS 90) strictly regulates industrial effluents discharged into marine and continental waters. Facilities face crippling shut-downs without Zero Liquid Discharge (ZLD) systems that convert hazardous runoff into certified non-leachable cake and reusable process water.
- Strict limits on heavy metals (Cu, Mo, As)
- Total Dissolved Solids (TDS) abatement mandates
- Automated real-time regulatory logging integration
Macro Solutions
Engineering Solutions for International EPCs & Industrial Plants
Tongjie bridges the engineering gap between Chinese advanced fabrication capacity and Latin American site deployment requirements.
Customized OEM/ODM Skid Engineering
We build tailor-made containerized systems for engineering brands worldwide. Whether you require specific pump vendors (Danfoss, Grundfos), membranes (DuPont, Hydranautics), or localized PLC frameworks (Siemens, Rockwell/Allen-Bradley), our team adheres strictly to your design packages and white-label branding specifications.
High-Altitude Electrical & Structural Design
Industrial installations above 3,500 meters in the Chilean Andes suffer from low atmospheric pressure and degraded cooling capacity. We design our skids with derated motors, oversized VFD heatsinks, insulated 40HQ refrigerated/heated containers, and seismic-resistant piping matrices compliant with NCh433 seismic codes.
Zero Liquid Discharge (ZLD) Trains
Combining Disc Tube Reverse Osmosis (DTRO), Osmotically Assisted RO (OARO), and Mechanical Vapor Recompression (MVR) thermal crystallizers. Our modular ZLD skids reduce liquid waste volume by 95-99%, isolating solid dry salts and eliminating catastrophic tailings dam failures.

AI-Automated Zero-Carbon Desalination
Full integration with off-grid photovoltaic arrays and green hydrogen power. SCADA systems equipped with neural networks for real-time predictive membrane fouling analysis and self-optimizing clean-in-place (CIP) regimens.
Compliance & Support
Chilean Localization & International Compliance Assurance
Robust manufacturing workflows verified under globally recognized quality and safety credentials.
CE Mark Certification
Full conformance with the EU Machinery Directive (2006/42/EC), Low Voltage Directive (2014/35/EU), and Pressure Equipment Directive (PED 2014/68/EU), ensuring complete mechanical and electrical safety verification.
Bilingual Engineering Specs
All delivered P&IDs, electrical schematics, PLC alarm indices, and Operations & Maintenance (O&M) handbooks are supplied in verified Spanish and English, streamlining local Chilean SEC (Superintendencia de Electricidad y Combustibles) filings.
Corrosion-Resistant Metallurgy
Coastal and high-saline operations demand superior alloys. We fabricate all high-pressure manifolds from 2507 Super Duplex Stainless Steel (UNS S32750), 904L, or Hastelloy C-276, paired with robust vinyl ester and FRP low-pressure circuits.
Factory Acceptance Testing (FAT)
Every system undergoes full hydraulic pressure testing, electrical fault simulation, and sensor calibration in our Shanghai facility before crating, significantly compressing on-site commissioning to under two weeks.
Engineering FAQ
Technical & Commercial Answers for Project Developers
Specific insights regarding supply logistics, component brands, and high-altitude integration in Chile.
How do you address high-altitude Andean derating (3,000+ MASL) for motors and control cabinets?
Due to lower air density at elevations like Calama or San Pedro de Atacama, standard electric motors overheat rapidly and dielectric clearance distances decrease. We counter this by selecting Class H insulated motors derated by 15-25%, using positive-pressure air-conditioned control enclosures, and specifying high-altitude rated variable frequency drives (VFDs) and contactors.
Can we specify European or US electrical components (e.g., Rockwell, Schneider, Endress+Hauser)?
Yes. As an ODM/OEM partner to international EPCs, we regularly construct skids according to precise procurement specifications (Approved Vendor Lists). We routinely integrate Schneider Electric, Siemens, or Rockwell Automation PLCs and HMIs, alongside Endress+Hauser or Emerson analytical instrumentation for seamless factory integration.
What is the lead time for standard containerized SWRO units shipped to Puerto San Antonio or Iquique?
Standard containerized SWRO plants (500 to 3,000 m³/day) have an engineering and manufacturing timeline of 8 to 12 weeks from P&ID sign-off. Ocean shipping from Shanghai or Ningbo to main Chilean container terminals (San Antonio, Valparaíso, Iquique, Antofagasta) typically takes 32 to 38 days.
How does your CE certification translate to Chilean national regulations?
CE certification assures third-party audit conformity with stringent mechanical stress tests, welding inspections (WPS/PQR), and electromagnetic shielding. In Chile, CE compliance documentation accelerates SEC electrical declarations and streamlines approval under the Environmental Assessment System (SEIA).
