Influencing Factors: Membrane Properties and PVDF MBR Efficiency
In membrane bioreactor the realm of membrane bioreactors (MBRs), polyvinylidene fluoride (PVDF) membranes are widely employed due to their robust characteristics and resistance to fouling. The effectiveness of these MBR systems is intrinsically linked to the specific membrane properties, comprising pore size, hydrophobicity, and surface charge. These parameters influence both the filtration process and the susceptibility to biofouling.
A finer pore size generally results in higher removal of suspended solids and microorganisms, enhancing treatment efficacy. However, a more hydrophobic membrane surface can increase the likelihood of fouling due to decreased water wetting and increased adhesion of foulants. Surface modification can also play a role in controlling biofouling by influencing the electrostatic interactions between membrane and microorganisms.
Optimizing these membrane properties is crucial for maximizing PVDF MBR performance and ensuring long-term system durability.
