Reinfored PTFE Hollow Fiber MBR Membrane Bio Reactor For Domestic Sewage Treatment

Reinfored Hollow Fiber MBR Membrane for Domestic Wastewater Treatment with PVDF/PTFE

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.
