Hollow Fiber Membrane

Hollow Fiber Membrane

The hollow fiber membrane has a fibrous shape and a self-supporting membrane. It is a kind of asymmetric membrane, and its dense layer can be located on the outer surface of the fiber(such as reverse osmosis membrane)

Description

The hollow fiber membrane has a fibrous shape and a self-supporting membrane. It is a kind of asymmetric membrane, and its dense layer can be located on the outer surface of the fiber(such as reverse osmosis membrane), or on the inner surface of the fiber (such as microfiltration membrane, nanofiltration membrane and ultrafiltration membrane). For the gas separation membrane, the dense layer may be located on either the inner surface or the outer surface. The hollow fiber tube wall is covered with micropores, which can remove most bacteria, virus, microbe, particles, colloid, macro molecules organism etc. And the pore size is expressed by the molecular weight of the trapped substance, which can be up to several thousand to several hundred thousand.

Advantages of reinforced PVDF hollow fiber membrane:

1.Reinforced PVDF with highly auti-pollution ability, good mechanical intensity, easy to clean, especially suitable for sewage and wastewater treatment application.

2.Good chemical stability, resistant to acid&alkali, anti-bacterial corrosion, long lifespan(3-5 years).

3.Air blowing can scour and clean the surface of fiber, no easy to be clogged.

4.High potting fiber area, high design flowrate.

5.Uniformly distributed asymmetric pores on fiber surface, can ensure a better interception, have a good water quality.

Application of reinforced PVDF hollow fiber membrane:

1.Domestic sewage treatment 7.Plating wastewater treatment
2.Municipal wastewater treatment 8.Chemistial wastewater treatment
3.Industry wastewater treatment 9.Food influent treatment
4.Laundry wastewater treatment 10.Oil field wastewater treatment
5.Dyeing wastewater treatment 11.Effluent recycling
6.Slaughter wastewater treatment 12.Hospital wastewater treatment
