Introduction
Feicheng, Shandong — 3E MEMTECH Pte. Ltd., leveraging its internationally leading membrane solutions, has partnered with Feicheng Water Group to successfully complete a landmark water quality enhancement project at the Taodu Dong Water Plant. By implementing Double-Membrane Process, the plant now delivers higher-grade, safer, and more reliable drinking water to more than 80,000 residents, businesses, and institutions, raising the bar for green, low-carbon municipal water production in the region.
Project Overview
Industry-Academia-Research Synergy
-
Technical Collaboration ：
With a total investment of RMB 47.22 million, the Dong Water Plant built a modern Double-membrane workshop (22 m × 65 m) equipped with three NF and two RO units. Together with 3E, a Nanofiltration Membrane Innovation &R&D Centre has been established to focus on continuous optimization and future advancements.
Post-treatment, the plant’s water quality exceeds GB/T 5749-2022 Standards for Drinking Water Quality, ensuring safe, premium-quality drinking water for 80,000 residents and surrounding enterprises — setting a new municipal water supply benchmark.
-
Research-to-Application：
The NF technology was developed by the team led by Academician Chung Tai-Shung Neal at the National University of Singapore. As the technology’s industrialization partner, 3E MEMTECH delivered end-to-end technical, engineering, and localization support, successfully translating this world-class innovation into operational excellence in China.
Core Technology
Building a Robust Pretreatment Barrier
- 3E NF-01 Membrane System:
Superior purification performance — Effectively removes a broad range of organic contaminants, with CODcr removal consistently above 30%.
Operational stability with energy savings — Runs at just 1–1.5 bar, minimizing energy consumption.
Low-carbon, sustainable model — Exceptional anti-fouling performance and adaptability to raw water variations; eliminates the need for chemical coagulation pretreatment; reduces chemical use by over 70% compared to conventional processes.
Core Benefits
Greater operational stability
Lower RO membrane scaling and fouling risk
Reduced maintenance and lifecycle costs
Extended RO membrane lifespan
Higher total water recovery rate
Optimize overall operating costs
Looking Ahead
The Feicheng project marks the beginning of a broader transformation. 3E MEMTECH will continue delivering advanced membrane solutions, innovative management models, and cutting-edge technologies. Plans are underway to create a public science and education zone at the plant to promote water conservation and environmental awareness.
With deepened industry-academia-research collaboration, 3E MEMTECH is committed to driving green, low-carbon, sustainable water industry development, generating social and economic value for communities and industries alike.
