1. Brief Introduction

Ultrafiltration (UF) involves pressure-driven separation of materials from a feed solution. The technology is used to remove particulate and microbial contaminants, but it does not remove ions and small molecules. Pressure drives the process, which typically operates with a feed pressure of 4 to 100 psi. UF plants are automated and have low operational labor requirements. UF membranes have a service life of three to five years or longer, which is comparable to reverse osmosis membranes.

UF modules are commercially available in tubular, hollow-fiber, plate and frame, and spiral wound configurations.

UF membranes reject solutes ranging size from 0.01 microns to 0.1 microns. Equal to the molecular weight cut-off (MWCO) 1000-500,000 daltons.

Different membrane materials with the same nominal MWCO may have different rejection rate. Because the pore size distribution and uniformity affect the reject performance.

The chemical nature of the membrane material also affect the membrane fouling-rejection.

So the membrane flux rate, rejection performance and anti-pollution performance are most important for different UF modules.

 

2. Description of ultrafiltration modules

2.1 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%.
