Membrane Characteristics and Performance in PVDF MBR Systems
In 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, including pore size, ultra-filtration membrane 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 efficiency. , On the other hand, a more hydrophobic membrane surface can increase the likelihood of fouling due to decreased water wetting and increased adhesion of foulants. Surface charge 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 stability.
