The ultrafiltration of hollow fiber membranes is a filtration and separation unit based on the principle of screening. It has the characteristics of high filtration accuracy and suitable for various water quality. Zhongtian Membrane Technology Co., Ltd. uses amphiphilic modifiers to hydrophilize the membrane materials, which greatly improves the hydrophilicity of the membrane filaments. Combined with the excellent oxidation resistance of polyvinylidene fluoride materials, the resulting Hollow fiber ultrafiltration membrane with large volume, excellent pollution resistance and oxidation resistance.
The more prominent features of hollow fiber membranes are:
1. High membrane strength
Because the polypropylene hollow fiber membrane adopts the "melt extrusion, stretch forming" film production method, the polypropylene macromolecules are regularly oriented, so the strength of the membrane is high, and it is not easy to break during the high-strength aeration and chemical cleaning process. wire.
2. The chemical stability of the membrane is good
In the process of making polypropylene hollow fiber membranes, no additives and porogens are added, so the chemical stability is good. It can be cleaned with strong acid, strong alkali and chlorine-containing disinfectant, and the membrane flux after cleaning is restored.
3. Unique structure design
The membrane module has a unique flow channel, water distribution and membrane filament root protection structure design, which not only protects the membrane filament roots from severe impact, but also better guarantees the even hydraulic distribution.
