Membrane Bioreactor (MBR)

The Membrane Bioreactor (MBR) specification in short includes the following key points:

1. Membrane Type: Ultrafiltration (UF) or Microfiltration (MF) membranes.
2. Pore Size: Typically between 0.01 to 0.1 microns.
3. Material: Membranes are often made from materials like PVDF (polyvinylidene fluoride) or PES (polyethersulfone).
4. Membrane Configuration: Hollow fiber, flat sheet, or tubular.
5. Flux Rate: Membrane flux usually ranges from 10 to 30 liters per square meter per hour (LMH).
6. Operating Pressure: Typically between 0.1 to 0.5 bar for vacuum-driven systems.
7. Biological Treatment: Often includes activated sludge for biological treatment.
8. Permeability: Should have high permeability for efficient filtration.
9. MLSS Concentration: Can handle up to 10,000–15,000 mg/L of Mixed Liquor Suspended Solids (MLSS).
10. Cleaning Mechanism: Periodic backwashing or chemical cleaning to prevent fouling.
11. Applications: Wastewater treatment, especially in municipal, industrial, and hospital settings.

These are the typical factors considered for MBR systems used in water and wastewater treatment processes.
