Membrane Characteristics and Performance in PVDF MBR Systems
In the realm of membrane bioreactors (MBRs), polyvinylidene fluoride (PVDF) membranes are widely employed due to here their robust attributes and resistance to fouling. The efficiency of these MBR systems is intrinsically linked to the specific membrane properties, including pore size, hydrophobicity, and surface modification. 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 performance. Conversely, a more hydrophobic membrane surface can increase the likelihood of fouling due to decreased water wetting and increased adhesion of foulants. Surface treatment 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 productivity and ensuring long-term system reliability.
