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.
The Comparision of the kind of membrane :
| Hollow Fibre | Spiral-wound | Ceramic Tubular | Plate and Frame |
| PH | 2-13 | 2-11 | 3-7 | |
| Feed Pressure(psi) | 9-15 | <30-120 | 60-100 | |
| Backwash Pressure(Psi) | 9-15 | 20-40 | 10-30 | |
| Temperature(°c) | 5-30 | 5-45 | 5-400 | |
| Total Dissolved Solids(mg/L) | <1000 | <600 | <500 | |
| Total Suspended Solids(mg/L) | <500 | <450 | <300 | |
| Turbidity(NTU) | <15 | <1 | <10 | |
| Iron(mg/L) | <5 | <5 | <5 | |
| Oils and Greases(mg/L) | <0.1 | <0.1 | <0.1 | |
| Solvents , phenols(mg/L) | <0.1 | <0.1 | <0.1 | |
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.
