2026年3月12日158.DIEN WATER GROUP: Professional Ultra-filtration System Manufacturer

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.
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
As a specialized ultra-filtration system manufacturer, we produce a comprehensive range of UF solutions:
Hollow Fiber UF Systems: High-flow configurations for industrial applications
Pressure Vessel Configurations: Multiple membrane elements in series
Submerged UF Systems: For high-turbidity and wastewater applications
Custom Skid-Mounted Units: Pre-engineered and ready for installation
Point-of-Entry Systems: Whole-building protection
Compact UF Units: For restaurants, hotels, and offices
UF Pretreatment Packages: Integrated with RO systems
Inside-Out Flow Configuration: Standard for most applications
Outside-In Flow Configuration: For high-solids streams
Various Molecular Weight Cutoffs: From 5,000 to 150,000 Daltons
Multiple Diameters: 4-inch, 6-inch, and 8-inch elements
Hollow Fiber Cartridges: Ready-to-install modules
Custom Lengths and Configurations: OEM/ODM options available
Replacement Modules: Compatible with major brands
