Hollow fiber membranes play a significant role in medical and industrial fields. They are used for different filtration and purification processes. These membranes are widely used for their efficiency and technology. Effective removal of contaminants and dissolved substances is important in reverse osmosis and ultrafiltration.
Let’s take a detailed look at what is hollow fiber membrane technology.
Everything You Need to Know About Hollow Fiber Membrane Technology
Hollow fiber filtration is like a semi- permeable membrane. It is like a tube with less than a millimeter diameter. It works on the similar concept of capillary configuration. However, it uses small tube diameter allowing flexibility.
It contains thousands of porous, long filaments.
The filaments are potted together in a PVC shell.
Each filament ranges from 1 to 3.5 mm.
They are flexible with narrow diameter.
Common applications- reverse osmosis and microfiltration.
These filaments resembling tiny straws are bundled for creating the filter matrix. The walls of the tubes contain holes/ microscopic pores. When you pump the water through the pump, contaminants and microbiological threats get trapped inside.
This filtration method is also known as size exclusion. The pores are too small in size, simply microscopic. They allow the smaller molecules i.e. water to pass and retains the contaminants.
Bundling small fibers creates a substantial membrane surface in a small volume, increasing the filtration capacity.
Hollow fiber membranes need lesser space than flat- sheet membranes.
Fibers offer their own mechanical support. It simplifies design and use.
These membranes have diverse applications in various industries.
It is easy to clean and maintain in the long- run.
Now, that we have had a look at what is hollow fiber membrane technology, it’s time to dig a little deeper into the types of membranes and its applications.
How Can RPVDF Technology Membrane for Water Treatment Benefit
RPVDF- Reinforced Polyvinylidene Fluoride is a type of hollow fiber membrane. Particularly, it is used in different types of separation and filtration processes. In addition, water management, wastewater treatment, and gas separation are also some of the major processes that use RPVDF technology.
These membranes are made of PVDF polymer. However, it is durable and chemical resistant with added reinforcement. This leads to enhanced strength. So, let’s dive deeper into how RPVDF works:
PVDF is a popular choice for membrane production.
It offers thermal stability, chemical resistance, and mechanical strength.
PVDF has hydrophobic properties and offers resistance to fouling.
PVDF is efficient in filtration of gases and liquids.
About Reinforcement Technology
The technology adds to the existing benefits of PVDF membranes. It improves the structural integrity and mechanical strength of the PVDF membranes. Reinforcement technique is deployed in the manufacturing process itself.
The technique works by adding the desired structure and material into the membrane matrix. It enhances the durability of the hollow fiber membranes.
