Life Sciences & cGMP Pharmacopeia

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.

Micro-Electronics & Sub-Nanometer Cleanliness

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.

ZLD & Heavy Industrial Decarbonization

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.

Technical Roadmap

Engineering Frontiers: Membrane Technology & Energy Recovery

Tongjie’s dedicated R&D roadmap integrates next-generation nanomaterials and smart IoT diagnostics to lower lifecycle costs (LCOW).

01

Fouling-Resistant Graphene & TFC Membranes

Integrating zwitterionic surface coatings and covalent graphene-oxide layers to elevate chlorine resistance and mitigate severe biofouling in high-COD wastewater matrices.

02

Isobaric Energy Recovery Integration

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.

03

Digital Twin & Predictive Membrane SCADA

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.

04

DQ / IQ / OQ / PQ Validation Packs

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.

Global Field Dispatch & Remote Telemetry

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.

Technical FAQ

Engineering Inquiries & Specification Guidance

Essential answers regarding feed water sizing parameters, membrane lifetime preservation, and validation documentation.

What minimum chemical inputs are required for system sizing?

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.

How does Tongjie control microbial biofilm in purified loops?

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.

What is the typical delivery schedule for containerized units?

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.

Can you provide custom OEM/ODM branding for engineering contractors?

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.
