What is the Operation Pressure of the MBR Membrane?

Table of Contents

Ensuring the right conditions for each process is crucial in wastewater treatment. One of the key parameters when it comes to Membrane Bioreactor (MBR) systems is the operation pressure of the membrane.

The operation pressure of an MBR membrane typically falls within the range of -0.01 to 0.03 MPa. In terms of bar, this translates to approximately -0.1 to 0.3 bar. This pressure range ensures that water is effectively pushed through the membrane, allowing contaminants to be filtered and producing clean water.

Understanding the operation pressure is essential as it directly impacts the efficiency of the filtration process. The pressure ensures that water is pushed through the membrane, allowing for the removal of contaminants while producing clean water.

Why is Operation Pressure Important?

The proper operation pressure ensures that the membrane functions optimally. Too high or too low pressure can affect the membrane’s lifespan and the quality of the treated water.

Factors Affecting Operation Pressure

  1. Membrane fouling: Over time, particles can accumulate on the membrane surface, leading to increased resistance and thus requiring higher operation pressure.
  2. Membrane type: Different membranes may have varying optimal operation pressures.
  3. Flow rate: The rate at which water is fed into the system can influence the required operation pressure.

How to Maintain Optimal Operation Pressure?

Regular maintenance and cleaning of the MBR system help maintain the right operation pressure. Monitoring the system and making necessary adjustments can also ensure the pressure remains within the desired range.


The operation pressure of an MBR membrane is a critical factor in the wastewater treatment process. By understanding its importance and ensuring it remains within the optimal range, one can achieve efficient wastewater treatment and prolong the lifespan of the membrane.

The above is information about the operation pressure of the MBR membrane. If you still have questions about the membrane bioreactor or need to purchase MBR membranes, don’t hesitate to contact SPERTA.
