DIEN WATER GROUP: Professional Ultra-filtration System Manufacturer

Who We Are

DIEN WATER GROUP is a leading ultra-filtration system manufacturer based in China, specializing in the design, production, and global supply of advanced ultrafiltration (UF) membrane technologies. With years of membrane expertise and state-of-the-art manufacturing facilities, we serve commercial, industrial, and municipal clients across North America, Europe, Southeast Asia, the Middle East, and Africa.

What is Ultrafiltration?

Ultrafiltration (UF) is a membrane filtration process that removes suspended solids, bacteria, viruses, and high-molecular-weight compounds from water. Operating at pressures between 0.1 to 1.0 MPa, UF membranes with pore sizes ranging from 0.01 to 0.1 microns provide an effective barrier against:

Bacteria (up to 99.9999% removal)
Viruses (up to 99.99% removal)
Colloidal particles
Silt and turbidity
High molecular weight organics
