From membrane module installation and pipeline welding to control cabinet wiring and overall corrosion protection, every detail reflects our professional expertise.
3. Flexible OEM cooperation models
⢠Customized Design Service: Customers provide complete design drawings and technical specifications; we handle procurement, production, testing, and packaging.
⢠Core component manufacturing: Professional components such as membrane housings, precision filters, integrated water purification systems, and modular integrated equipment are produced on commission.
⢠Half-finished product assembly + final assembly: Reduce customers' overseas factory construction costs by providing pre-assembled modules or complete system assembly services.
⢠Joint R&D Implementation: When clients specify performance requirements, our engineering team assists in translating them into manufacturable solutions.
4. Exclusive Overseas OEM Service Chain
For overseas clients, Tongjie Environmental Protection offers multilingual technical support, export-standard packaging (rust-resistant, moisture-proof, fumigation-free wooden boxes), comprehensive sea and land transportation coordination, and remote installation guidance. Upon request, engineers can be dispatched to provide on-site support for the initial system commissioning abroad, ensuring OEM products are promptly operational upon arrival at the destination.
Industrial RO reverse osmosis pure water equipment; seawater desalination pretreatment system; DTRO/STRO high-pressure membrane integration unit; integrated MBR wastewater treatment system; zero-discharge concentrator for heavy metal wastewater; dual-membrane process package for reclaimed water reuse; mobile emergency water purification cabin; fully integrated landfill leachate treatment unit.
OEM Cooperation Process (Concise and Efficient)
-
1. Requirement Confirmation
The client provides technical specifications, design drawings, or sample requirements.
-
2. Process Review & Quotation
The Tongjie Engineering team evaluates feasibility and prepares the BOM (Bill of Materials) along with cost estimates.
-
3. Sample / Batch Trial
Optional sample validation; proceed to mass production after confirmation.
-
4. Mass Production & QC
Production is scheduled according to orders, with key quality control points monitored on-site.
-
5. Packaging & Shipping
Provides customs clearance documents, certificates of conformity, and operating manuals (bilingual).
-
6. After-Sales Support
12-hour response, remote video assistance, and rapid parts delivery.
What types of water treatment equipment can Tongjie manufacture on an OEM basis?
Tongjie provides full-spectrum OEM manufacturing for industrial pure water RO systems, seawater desalination plants, DTRO/STRO high-pressure membrane units, integrated MBR systems, heavy metal zero-discharge concentrators, reclaimed water reuse dual-membrane systems, mobile emergency water purification units, and landfill leachate treatment packages.
What OEM cooperation models are available for overseas partners?
We provide four flexible collaboration models: 1) Customized Design Services based entirely on client drawings; 2) Core Component Manufacturing (membrane housings, modular skids, filters); 3) Semi-finished module assembly + final integration; and 4) Joint R&D implementation where we translate client specifications into mass-producible equipment.
How does Tongjie guarantee quality control during OEM manufacturing?
Every OEM product line complies strictly with ISO quality systems and employs core parts from global brand suppliers. All equipment undergoes triple testing before shipping: hydrostatic pressure tests, dynamic water flow tests, and electrical control simulations.
What export packaging and logistics support do you provide for international shipments?
All units are packaged according to international export standards, using rust-resistant, moisture-proof, and fumigation-free wooden cases. We provide full customs clearance documents, bilingual operating manuals, certificates of conformity, and comprehensive sea/land logistics coordination.
Can Tongjie dispatch engineers for on-site commissioning abroad?
Yes. In addition to 12-hour fast remote technical response and video assistance, we can dispatch skilled engineers overseas upon request to guide installation, perform initial commissioning, and ensure rapid, reliable operation.
How quickly can Tongjie provide a project evaluation and BOM quotation?
Once you provide the design drawings or performance requirements, our 20+ year engineering team immediately evaluates project feasibility and typically delivers a comprehensive Bill of Materials (BOM) and cost estimate within a few business days.
