Barcelona & Catalonia: Industrial Produced Water & High-Salinity Matrix
Addressing persistent Mediterranean hydrologic stress through decentralized, high-recovery membrane engineering and circular effluent reutilization.
Port of Barcelona & Energy Hubs
The Port of Barcelona hosts Southern Europe’s major regasification terminal (Enagás) alongside key marine bunkering and petrochemical blending facilities. These operations generate complex produced brine, containing hydrocarbons, heavy metals, and hypersaline washings. Tongjie’s disc-tube and double-stage membrane skids allow local terminal operators to achieve near-zero hazardous discharge into the Mediterranean coastline.
Baix Llobregat & Vallès Industrial Clusters
Situated within the industrial belts of Martorell, Castellbisbal, and Granollers, heavy chemical, automotive, and specialty polymer plants operate under stringent Catalan Water Agency (Agència Catalana de l'Aigua - ACA) regulations. Faced with severe multi-year drought alerts, local plants rely on our high-efficiency demineralization and produced water treatment systems to recycle process streams into boiler feed or cooling makeup water.
Decarbonization & Green H2 Corridors
Catalonia's hydrogen valley initiative (Vall de l'Hidrogen de Catalunya) demands massive volumes of demineralized feed water without depleting regional municipal reservoirs. Tongjie provides OEM containerized sea water reverse osmosis (SWRO) and produced water recycling units capable of purifying degraded saline effluents into ultra-pure feed (conductivity <0.1 μS/cm) for PEM and alkaline electrolyzers.

Engineering Blueprint
Multi-Stage Process Architecture: Produced Water to Ultra-Purity
The integrated mechanical, chemical, and membrane sequence driving zero liquid discharge across Mediterranean applications.
STAGE 01
Hydrocarbon & Oil Coalescence
CPI separation, DAF clarification, and ceramic microfiltration reduce free and emulsified oil to ≤5 mg/L, safeguarding membrane envelopes from irreversible fouling.
STAGE 02
Chemical Softening & Degassing
Lime-soda or caustic dosing precipitates silica, barium, strontium, and calcium. Integrated membrane deoxygenation extracts dissolved oxygen down to trace ppb tiers.
STAGE 03
High-Pressure DTRO / OARO
Operates under fluid pressures up to 120 bar. Open hydraulic geometry accommodates TDS levels surpassing 80,000 ppm while generating purified permeate.
STAGE 04
MVR Thermal Crystallization
Mechanical Vapor Recompression (MVR) evaporates concentrated brine residues. Pure water distillate is recycled to boiler feed while clean dry salts are recovered.
China Supply Chain Resilience & Shanghai Tongjie Engineering Rigor
Shanghai Tongjie operates a specialized manufacturing base of over 15,000 square meters in Shanghai's advanced Jiading industrial district. By consolidating ASME-certified pressure vessel manufacturing, titanium & Super Duplex stainless steel (2507) TIG welding, advanced PLC cabinet integration, and high-pressure testing loops under one roof, Tongjie eliminates sub-supplier bottlenecks.
Direct marine shipping from the Port of Shanghai to the Port of Barcelona ensures reliable delivery schedules within 28 to 35 maritime days, supported by complete bilingual (English/Spanish) design dossiers, 3D BIM integration models, and comprehensive CE Machinery Directive compliance documents.
Catalan Framework
Catalonian Regulatory Adherence & Technical Backing
Ensuring complete compatibility with Spanish Royal Decrees and European Union industrial water reuse directives.
Real Decreto 1620/2007 Compliance
All Tongjie reclaimed effluent systems are sized to meet or exceed Spanish legal limits for industrial water reuse (RD 1620/2007), including strict limits for suspended solids (≤5 mg/L), turbidity (≤1 NTU), and Legionella elimination across cooling loop recycling schemes.
CE Directive & ATEX Directives
For chemical and hydrocarbon environments in the Port of Barcelona and Zona Franca, systems are built with CE Machinery Directive (2006/42/EC), Low Voltage Directive (2014/35/EU), and ATEX-certified explosion-proof motor and instrumentation assemblies.
Full Life-Cycle Field Services
Through our established global service engineering teams, we offer comprehensive supervision of on-site installation, local operator training in Spanish or English, preventative maintenance schedules, and rapid air-freight spare parts delivery across Iberia.
Engineering Q&A
Frequently Asked Questions: Industrial Water Engineering
Authoritative technical insights for EPC consultants, procurement directors, and plant utilities managers.
How do Tongjie DTRO systems prevent severe organic fouling when treating oilfield produced water in Mediterranean installations?
Unlike conventional spiral-wound membranes where narrow feed spacer meshes trap suspended oils and colloidal organics, Tongjie's Disc Tube Reverse Osmosis (DTRO) modules utilize an open-channel hydrodynamic geometry. Feed solution flows radially across planar circular membrane cushions separated by ribbed hydraulic discs. High-frequency turbulent cross-flow minimizes boundary layer concentration polarization, allowing continuous processing of streams with COD up to 20,000 mg/L and silt density index (SDI) >5 without irreversible plugging.
Can the treated water meet reinjection or high-temperature boiler feed criteria under Catalan ACA discharge limits?
Yes. By coupling primary chemical softening and coalescing filtration with dual-stage DTRO and continuous electrodeionization (EDI), effluent hydrocarbons are reduced to ≤5 mg/L, total suspended solids to ≤1 mg/L, and electrical conductivity to <0.1 μS/cm with silica <10 ppb. This performance fully meets both underground well reinjection standards and HP boiler water specifications (such as VGB-S-010).
What are the energy consumption benchmarks for containerized SWRO and high-salinity brine concentration units?
Tongjie incorporates high-efficiency isobaric energy recovery devices (ERDs, such as energy recovery turbines or pressure exchangers) into all marine and high-salinity brine concentration skids. For typical Mediterranean seawater (TDS ~38,000 ppm), specific energy consumption (SEC) ranges between 2.8 and 3.4 kWh/m³ of permeate produced, offering substantial OPEX savings compared to thermal distillation alternatives.
What is the standard delivery timeline from purchase order sign-off to port arrival in Barcelona?
Standard skid-mounted units require 8 to 12 weeks for detailed engineering, P&ID sign-off, frame welding, piping assembly, and comprehensive FAT at our Shanghai facility. Containerized plug-and-play packages take approximately 12 to 14 weeks. Maritime transit from Shanghai to Barcelona typically requires 28 to 35 calendar days, arriving ready for immediate mechanical tie-in.
How does Tongjie support European EPC contractors during the commissioning and CE certification validation stages?
Tongjie provides full technical documentation dossiers compliant with the EU Machinery Directive, including detailed P&IDs, electrical schematics (EPLAN format), functional logic descriptions, valve matrices, structural stress reports, and certificates of origin and materials (EN 10204 3.1). Furthermore, Tongjie deploys multilingual commissioning field engineers for on-site startup or provides remote live telemetry supervision.
