Which type of filter is utilized in Membrane Bioreactors?

• A. Microfiltration
• B. Ultrafiltration
• C. Reverse Osmosis
• D. Activated Carbon

Answer: (B)

In Membrane Bioreactors (MBRs), ultrafiltration is the type of filter utilized. This process involves membranes that have pore sizes large enough to allow water and dissolved substances to pass through while retaining suspended solids, bacteria, and other microorganisms. Ultrafiltration membranes generally have pore sizes ranging from 0.01 to 0.1 micrometers, making them effective for separating biological solids from the treated water. The use of ultrafiltration in MBRs is particularly advantageous because it helps in achieving high-quality effluent that is free from pathogens and suspended particulates, thus making it suitable for reuse or further treatment. The combination of biological treatment and membrane filtration in MBRs enhances the process efficiency and enables better control over the effluent quality compared to other filtration methods. This integration of biological and membrane technologies has become a key feature in advanced water treatment processes.
