MBR Membrane Daily Maintenance: Tips to Maximize Efficiency and Lifespan
The MBR membrane (Membrane Bioreactor) is a core component of modern wastewater treatment systems. Known for its compact design and high-quality effluent, MBR systems are widely used across industrial and municipal projects. However, maintaining long-term membrane performance requires consistent daily maintenance and monitoring.
Why Daily Maintenance Matters
Without proper maintenance, membrane systems are prone to fouling, TMP spikes, or unbalanced air distribution—all of which lead to reduced efficiency and higher operational costs. Below are key aspects of daily MBR membrane inspection:
1. Check Aeration Distribution
Uneven or insufficient aeration can cause sludge build-up on the membrane surface. It is essential to check blower performance and ensure uniform air distribution across all zones.
2. Monitor Transmembrane Pressure (TMP)
TMP should rise gradually during normal operation. A sudden increase often indicates clogging. In such cases, physical or chemical membrane cleaning should be performed immediately, and performance should be monitored after cleaning.
3. Maintain Proper Water Temperature
Most MBR membranes operate efficiently within 15°C to 40°C. Extreme temperatures outside this range may affect membrane integrity and flux rate. Use insulation or heating/cooling methods as needed.
4. Keep Inlet pH in Range
Inlet pH should be kept between 6.5 and 8.5. Use appropriate dosing systems to adjust as necessary. Avoid excessive use of lime, which can lead to inorganic scaling and faster membrane fouling.

Conclusion
Consistent MBR membrane daily maintenance is essential for maximizing system efficiency and minimizing operational issues. We recommend implementing a standardized inspection checklist and keeping track of all TMP readings and cleaning activities. Preventive maintenance not only extends membrane life but also enhances the reliability of your wastewater treatment operations.
