Semiconductor ultrapure water system 18.2MΩ·cm TOC<1ppb for semiconductor wafer cleaning, dual-stage RO EDI reverse osmosis unit, pump PLC

Fully automatic food and beverage liquid nitrogen quantitative feeder filling machine designed for energy drinks, fruit juices, and drinking water applications. Specialized medical laboratory pure water treatment equipment for hospital medical water systems.

Shanghai Tongjie Environmental Technology Co., Ltd., a trusted name in industrial wastewater treatment and membrane separation technology, has successfully commissioned a customized STRO (Spiral Tube Reverse Osmosis) hospital wastewater treatment system for WuXi AppTec's manufacturing site in Singapore.

Designed for a treatment capacity of 4 tons per hour and a water recovery rate of 45%, the system addresses one of the most challenging industrial effluent profiles in the pharmaceutical sector.

Tongjie Environmental's STRO membrane technology offers a distinct advantage: its patented open-channel, low-fouling flow path design minimizes membrane blockage and enables stable, long-term operation even under extreme water quality fluctuations.

Ideal applications include:

• Hospital wastewater reuse
• Zero-liquid-discharge (ZLD) pretreatment
• High-salinity industrial water recycling applications

With over a decade of R&D and engineering experience, Tongjie Environmental specializes in:

• STRO/DTRO membrane systems
• Landfill leachate treatment
• Industrial zero-discharge solutions

The company has delivered hundreds of projects across China and export markets, including Southeast Asia, the Middle East, and South America.

Shanghai Tongjie Environmental Technology Co., Ltd. is a high-tech enterprise focused on the R&D, design, manufacturing, and after-sales support of advanced membrane separation systems. The company's core technologies include STRO, DTRO, NF, and UF membrane processes, serving industries such as medical, chemicals, landfill leachate, and power generation.
