Comparative Study Different Ultra-Filtration Membranes in MBR Applications
Membrane Bioreactors (MBRs) are becoming increasingly prevalent in wastewater treatment due to their high efficiency and reliability. A crucial component of an MBR system is the ultra-filtration (UF) membrane, responsible for separating suspended solids and microorganisms from the treated water. This study compares the performance of various UF membranes used in MBR applications, focusing on factors such as water recovery.

The objective is to provide insights into the optimal UF membrane selection for specific MBR applications, contributing to optimized treatment efficiency and water quality.
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 properties and resistance to fouling. The efficiency of these MBR systems is intrinsically linked to the specific membrane properties, including pore size, hydrophobicity, and surface texture. 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. , 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 efficiency and ensuring long-term system durability.
