High Performance Ultra-filtration Membrane Purification Equipment CE Certification
Classification of Ultrafiltration Membrane
The structure of UF Membrane can be divided into plate frame type(plate type) ,Hollow Fiber Type,Tubular Type ,Coil Type and so on .Among them ,the hollow fiber UF Membrane is the most mature and advanced form of ultrafiltration technology .The outer diameter of Hollow Fiber Membrane is 0.4--2.0mm,the inner diameter is 0.3--1.4mm,hollow fiber tube wall is filled with microporous,the pore size can intercept the molecular weight of the material expression,the interception of the molecular weight of up to several thousand to hundreds of thousands.The raw water flows by pressing of outside side of hollow fiber of inside the cavity ,that forming external pressure and internal pressure type of hollow ultrafiltration membrane respectively .The UF is a dynamic filtration process ,the intercepted molecular can be drainned with concentrate without blocking the surface of the memebrane and can run continuously for a long time.

Common Applications
- Municipal drinking water filtration
- Industrial waste water recovery
- COD reduction
- RO&NF pre-treatment
UF Work Principle
The Ultrafiltration is used to screening as separation principle ,that is process of membrane separation with the pressure ,the precision of filtration is in 0.005-0.01μm range,which can effectively remove particles ,colloids ,bacteria ,pyrogen and high polymer organic matter in water .It can be widely applied to the separation ,concentration,purification of substances .The Ultra filtration Process has no phase inversion , operation under normal temperature.It is better to separate for pyrogen ,and have good resistance heat ,resistance acid &alkali and oxidation resistance ,and it is continuously used under 60℃ and PH 2-11 for a long time.
What you can do
1.Tell us what`s your raw water as input water for our ro water treatment system first.If possible , it`s better you can give us a water analysis report ,so or engineer can design a suitable system to u.
2.Then tell us what`s the water production flow rate you need per hour ?
3.Tell us what`s the application of pure water from ro water treatment system,for drinking ,industrial,hospital,Pharmaceutical,chemical experiments,lab test or others ?
4.Lastly,pls tell us your requirements for the pure water quality ,material of pipes and filters housing,and the brands of meters and fittings.
We look forward to cooperating with you.
