MBR Systems – Superior Wastewater Treatment Performance with Membrane Bioreactor Technology and Automation
MBR (Membrane Bioreactor) systems are one of the most modern and highest efficiency treatment solutions, combining biological treatment with membrane filtration technology. In these systems, activated sludge processes are supported by micro or ultrafiltration membranes, effectively separating suspended solids, microorganisms and high molecular weight pollutants from the water. As a result, MBR technology provides much higher effluent quality compared to traditional treatment methods and offers superior performance in recovery applications.
The sustainable treatment efficiency of MBR systems is made possible by advanced automation solutions. Automation continuously ensures optimal operating conditions for the system by monitoring the trans-membrane pressure (TMP) of the membrane, controlling air distribution, monitoring sludge recirculation rates, and tracking membrane fouling and contamination effects in real time.
Advantages of MBR Systems
MBR technology is widely preferred today in both municipal and industrial facilities. Its advantages include:
- High Effluent Water Quality: Suspended solids and pathogens are effectively removed thanks to 0.02–0.1 micron pore size membranes.
- Compact Design: Biological ponds can be designed with smaller volumes because sludge ageing is more controlled.
- Stable Biological Process: Ensures a stable microorganism structure at high sludge age.
- Suitability for Recovery: Provides superior filtration for reuse areas such as irrigation, industrial processes, or cooling water.
- Less Odour and Noise: Much quieter and more environmentally friendly than traditional systems.
- Low Effluent Turbidity: Enables NTU values to drop below 0.2.
For these reasons, MBR systems are among the first choices for all modern treatment projects targeting high quality.
The Role of Automation in MBR Systems
MBR systems require the simultaneous control of many parameters. Therefore, automation is a critical component that maintains both membrane health and the continuity of biological treatment.
The main benefits provided by automation are:
- TMP (Trans Membrane Pressure) monitoring and automatic membrane protection
- Air distribution and aeration control
- Constant water level and constant flow control
- Automatic backwash and chemical cleaning (CIP) cycles
- Monitoring of sludge concentration, MLSS and SRT balance
- Remote control and data archiving with SCADA integration
- Optimisation of energy consumption and equipment loads
Thanks to these automation elements, MBR systems have a longer service life and significantly reduce maintenance costs.
Application Areas of MBR Systems
Common application areas for MBR technology include:
- Municipal wastewater treatment plants
- Industrial estates
- Food, beverage and chemical industries
- Textile and dye industries
- Tourism facilities and hotels
- Wastewater recovery and reuse facilities
- Modular and packaged treatment systems
MBR systems offer an ideal solution for all sectors requiring high effluent water quality.
