Strategies for Enhanced Fouling Resistance in MBR Systems
Membranes used in membrane bioreactor (MBR) systems are susceptible to fouling, a detrimental phenomenon that decreases their performance and operational efficiency. To mitigate this challenge, various optimization strategies can be employed. These strategies aim to minimize the deposition of inorganic matter on the membrane surface and enhance its cleaning potential. Some common approaches include optimizing process conditions, implementing pre-treatment techniques, utilizing specialized membranes with hydrophobic properties, and incorporating effective backwashing and chemical cleaning regimes.
The choice of optimal strategies depends on the specific characteristics of the feedstock stream and the operational requirements of the MBR system. Regular monitoring and fine-tuning of these strategies are crucial to maintain a efficient operation and minimize fouling-related issues.

Combined Operation of a Membrane Bioreactor System with Anaerobic Digestion
Membrane bioreactors (MBRs) and anaerobic digestion (AD) are recognized as efficient technologies for treating wastewater and generating biogas. Integrating these two processes offers several strengths, such as enhanced nutrient removal, increased methane production, and reduced sludge amounts. Additionally, the integration of MBRs with AD can improve the overall system efficiency by creating a symbiotic relationship where the discharge from the MBR serves as a valuable substrate for anaerobic digestion.
This interconnection typically involves connecting the permeate stream from the MBR to the AD reactor, providing the microorganisms with here readily available organic matter for decomposition. The resulting biogas can then be used as a green power or upgraded to biomethane for grid injection. The process effectively treats wastewater while simultaneously creating valuable resources, contributing to a more sustainable and circular economy.
