KYsearo is one of the specially authorised partner of TOYOBO in China. We use TOYOBO hollow fiber RO membrane to desalinate water in large systems of above 200TPD.TOYOBO hollow fiber RO membrane is the latest technological reverse osmosis membrane,its fresh water production capacity is 10 times than usual spiral wound membrane,so many seawater desalination successful huge projects are using this kind of membrane in Middle East area, and have kept 7 to 11 years working without replacing membranes. Kysearo takes 2000 TPD seawater desalination system as a group, all larger tons systems are designed upon this group, for example, 10000 TPD would be consisted of 5 groups of 2000 TPD system.
|The differences between Hollow Fiber and Spiral Wound RO Membrane|
1. More Simple Process Than Before
2. Membrane structure
3. Water production capacity
Hollow Fiber RO Membrane : Spiral Wound RO Membrane = 10:1
Hollow Fiber RO Membrane is wound efficiently in a cross-wound way without using additional base materials, The cross winding increases the hollow fiber spacing and improves its fouling resistance to achieve minimum pressure loss and uniform water flow, this way provide about 10 times the surface area compared to spiral wound elements.
This greater surface area is a key factor to product water capacity, therefore, hollow fiber RO membrane product about 10 times water capacity compared to spiral wound RO membrane.
4. How often change the RO membranes
Spiral Wound RO Membrane: 2~3 years
Hollow Fiber RO Membrane : 7~11 years
Here is average life comparison table of some large projects use Hollow Fiber RO Membrane.
