8040W Ulta-filtration Membrane Modules for Purified Water Treatment with Pore Size 0.05um PVDF material
1. Brief Introduction
Ultrafiltration membrane has the characteristics of strong pollution resistance, high membrane filament strength and high filtration accuracy. Canpure internal pressure ultrafiltration membrane can effectively reduce the turbidity of raw water, remove suspended matter, colloids, microorganisms and other substances in the water, have strong adaptability to changes in raw water quality, simple operation and maintenance, and stable and reliable water quality.
Permanent hydrophilic
Ultrafiltration membrane is made of PVDF material crosslinked with hydrophilic components. The deepening and fixing of the hydrophilic groups makes the hydrophilicity of the membrane filaments permanently retained, the water production flux is more stable, and the pollution resistance and cleaning recovery of the membrane are significantly improved.
High intensity and large flux
Unique membrane wire cross-section structure
Thicker film wire inner diameter
Description of CNKHONG ultrafiltration modules
Module Features
The CNKHONG Ultrafiltration modules are made of high strength hollow fiber membranes, they are made of Polyvinylidene Fluoride(PVDF). The pore size of 0.03 µm is enough for the removal of bacteria, viruses, and particles including all kinds of colloids. v
The membranes have been special treated to be hydrophilic. It is easy cleaning and wettability that help maintain long term performance. v Out to In flow configuration can endure high tolerance of feed solids. They also can be used pressed air to help the cleaning recovery.
The dead-end filtration way offer higher recovery rate and energy savings. The largest water recovering rate can be more can 95%.
