Explore our core engineered modules fabricated in Shanghai, tested to stringent factory acceptance criteria before global dispatch.
Strategic purchasing demands have moved far beyond standard off-the-shelf catalog filters to fully traceable, lifecycle-optimized separation architectures.
Global pharmaceutical corporations (US FDA, EMA, NMPA) enforce strict limits on bacterial endotoxins (<0.25 EU/ml) and total organic carbon. Turnkey systems require orbital welded 316L stainless steel piping, sanitary diaphragm valves, and validated dead-leg-free circulation loops capable of automated chemical or ozone sanitization.
Semiconductor fabrication plants require Ultrapure Water (UPW) approaching theoretical purity (18.2 MΩ·cm at 25°C). Critical procurement points include continuous deionization (CEDI), catalytic deoxygenation down to ppb levels, 185nm UV photochemical TOC reduction, and terminal ultrafiltration for sub-micron particle removal.
Stringent environmental laws in chemical, coal-power, and textile industries require near-zero liquid discharge. Global EPCs prioritize hybrid systems integrating Disc Tube Reverse Osmosis (DTRO), electrodialysis reversal (EDR), and high-efficiency mechanical vapor recompression (MVR) crystallization to minimize carbon footprints.
Custom-engineered process paths configured according to raw water chemical profile, operating recovery constraints, and effluent compliance guidelines.

Tongjie’s dedicated R&D roadmap integrates next-generation nanomaterials and smart IoT diagnostics to lower lifecycle costs (LCOW).
Integrating zwitterionic surface coatings and covalent graphene-oxide layers to elevate chlorine resistance and mitigate severe biofouling in high-COD wastewater matrices.
Employing state-of-the-art ceramic pressure exchangers yielding up to 98% hydraulic power recovery in seawater desalination, driving energy consumption below 2.8 kWh/m³.
Edge-computing IoT sensor nodes monitor differential pressures, normalized flux decay, and salt passage in real time to calculate automated Clean-in-Place (CIP) schedules.
Proprietary non-chemical electronic precipitation technologies designed to replace bulk antiscalant dosing, protecting downstream membranes from irreversible silica scaling.
Ensuring complete risk mitigation for engineering EPC contractors and multinational owners through transparent validation protocols and regional service networks.
Every industrial skid is certified under ISO 9001 (Quality), ISO 14001 (Environmental Management), and ISO 45001 (Health & Safety). Full CE marking ensures compliant integration across the European Economic Area.
Our engineering validation teams furnish complete documentation dossiers: traceability matrices, material test reports (MTR 3.1), weld map boroscope inspections, calibration certs, and comprehensive SAT scripts.
Through our established field presence in the Middle East, Central Asia, and Southeast Asia, our factory-trained commissioning technicians deliver rapid on-site start-up, operator training, and 24/7 cloud diagnostics.
Essential answers regarding feed water sizing parameters, membrane lifetime preservation, and validation documentation.
We require a comprehensive lab analysis covering Total Dissolved Solids (TDS), silica content (reactive and colloidal), hardness (Ca2+, Mg2+), iron/manganese, total organic carbon (TOC), sulfate, free chlorine, and Silt Density Index (SDI15). Process engineering calculations are mapped using projection software to verify membrane flux rates and anti-scaling requirements.
Our purified loops feature electropolished Ra ≤ 0.4 μm stainless steel surfaces, zero dead-leg valves (3D rule compliance), continuous turbulent flow (>1.5 m/s return velocity), automated thermal sanitization at 85°C, or electrolytic ozone dosing ensuring complete bio-sterilization without residual chemicals.
Standard containerized SWRO and industrial RO systems have a production schedule of 45 to 60 days. This includes CAD/P&ID sign-off, structural skid fabrication, membrane loading, complete hydraulic pressure testing, and Factory Acceptance Testing (FAT) in our Shanghai plant prior to international shipping.
Yes. Over 40% of our capacity is dedicated to private-label ODM/OEM manufacturing for international engineering firms. We accommodate custom brand colors, client-selected PLC hardware (Siemens, Allen-Bradley, Schneider), standardized tag numbering, and unbranded operational manuals.
