Hollow Fiber MBR Introduction
Membrane Bioreactor (MBR) is a new type of wastewater treatment
technology that combines high-efficiency membrane separation
technology with biochemical technology. The hollow fiber membrane
module directly performs solid-liquid separation in the biochemical
pool, replacing the secondary sedimentation tank in the activated
sludge method, and effectively achieves the purpose of muddy water
separation. The high-efficiency retention effect of the membrane
allows the nitrifying bacteria to be completely retained in the
bioreactor, so that the nitrification reaction can be smoothly
carried out, the ammonia nitrogen can be effectively removed, the
sludge can be avoided, and the macromolecular organic matter which
is difficult to degrade can be retained at the same time, and the
The residence time of the reactor is maximized. After applying MBR
technology, the main pollution removal rate can reach: COD≥93%, the
suspended solids and turbidity are close to zero, the water quality
is good and stable, and it can be directly reused to realize the
sewage resource.
Hollow Fiber MBR Advantages
1. High strength:
Reinforced composite PVDF hollow fiber membrane adopts unique
support layer membrane technology, which makes its tensile strength
and compressive strength much higher than ordinary hollow fiber
membrane, and the single membrane filament tensile force is greater
than 50KG. It is aptly called "pull continuous film".
2. Good anti-pollution performance:
Reinforced composite PVDF hollow fiber membrane adopts PVDF alloy
formula as its filtration layer, and its ultra-smooth membrane
surface characteristics and unique charge performance make it have
strong anti-pollution performance.
3. Super-large flux:
The reinforced composite PVDF hollow fiber membrane adopts a
relatively independent special support layer technology and PVDF
alloy membrane filtration layer technology, and the formed filter
layer has high porosity, and the produced membrane not only has
high strength but also good flux.
4. Good retention performance:
The reinforced composite PVDF hollow fiber membrane adopts PVDF
alloy membrane as the filtration layer, and its special inner and
outer dense double skin structure makes it have excellent retention
performance.
5. The cleaning flux recovery is good:
The reinforced composite PVDF hollow fiber membrane adopts PVDF
alloy membrane as the filtration layer, and its special inner and
outer dense double skin structure makes the pollutants only stay on
the outer surface of the membrane and does not enter the membrane
network. Inside the hole, it is very easy to clean and the cleaning
flux is restored.
6. The reinforced composite PVDF membrane module can be
modularized, compact in structure, small in footprint, and easy to
use in combination.
7. Reinforced composite PVDF sewage treatment special diaphragm has
a long service life, generally can reach 3-5 years.
8. The composite PVDF membrane has good chemical stability, acid
and alkali resistance, bacterial corrosion resistance and good
oxidation resistance.
9. The membrane module is provided with an aeration tube to wash
the membrane wire with water and water to maintain the flux of the
membrane. The surface of the membrane fiber can also be cleaned by
the aeration process of the biochemical pool to maintain a stable
water production.
