Introduction:
Understanding the Fundamentals of Hollow Fiber Filtration
- Hollow fiber filtration is a
cutting-edge membrane technology used for separating and purifying
substances in various industries.
- This innovative filtration method
employs hollow fiber membranes, which are hollow tubes with porous walls,
to achieve efficient separation of particles and molecules.
Principle of Operation:
How Hollow Fiber Filtration Works
- In Hollow
Fiber Filtration, feed solution is passed through the inside of
the hollow fibers, while purified filtrate is collected from the outside.
- The porous walls of the hollow
fibers act as a barrier, allowing only molecules of a certain size or
charge to pass through, while retaining larger particles and contaminants.
