What Is MBR Membrane Fouling?

Last Updated on December 28, 2022 by Kevin Chen

MBR Membrane fouling is the formation of impurity particles, colloidal particles, and solute macromolecules on the membrane surface or in the membrane pores due to physical, chemical, or mechanical interactions with the membrane during the water treatment process. It can lead to changes in the flux and separation characteristics of the MBR membrane. The immediate source of substances leading to MBR Fouling is the sludge mixture in the bioreactor, which contains the microbiota and its metabolites, organic macromolecules and small molecules in the wastewater, soluble substances, and solid particles.

How To Avoid MBR Membrane Fouling?

Poor feed water quality conditions basically cause MBR Fouling, so when MBR is fouling, it is recommended first to check whether the feed water meets the standard.

1. Strengthening pre-treatment, such as installing a fine screen less than 2mm, can filter out some of the larger impurities in the water, reducing the MBR membrane clogged and reducing the MBR membrane being polluted caused by large particles.

2. Put the MBR membrane module into operation only when the microorganism culture activity is good.

3. Intermittent operation: The suction pump operates for 8 minutes, stops for 2 minutes, avoids membrane pore clogging, and has a long time of stable work.

4. The aeration pipes at the bottom of the MBR membrane module can wash the surface of the MBR fibers by the bubbles and water flow.

5. In the initial operation, the smaller the negative suction pressure, the better. We can read suction pressure through the negative pressure gauge. Diaphragm regular operation negative pressure control in -0.005 – 0.02Mpa. Initially, it is best to be between 0.005 – 0.01Mpa.

What If The MBR Membrane Is Fouling?

If the MBR membrane is fouling, we can clean the MBR membrane. Generally, after cleaning, it can restore some of the performance. MBR membrane cleaning can be divided into physical cleaning and chemical cleaning. If both cleaning methods are used, but the MBR membrane still can not restore to the minimum flux demand, then we can only replace the new MBR membrane.

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

What Is The MBR Membrane Process?

The MBR Membrane process combines membrane separation technology with bioreactors for sewage treatment. It not only saves the construction of the secondary sedimentation tank but also greatly improves the efficiency of solid-liquid separation.

Will MBR membrane freeze in cold weather?

Will MBR Membrane Freeze In cold weather?

Will MBR membrane freeze in cold weather? That is a question many people are asking, especially those who live in colder areas. The answer is: No. The MBR membrane will not easily freeze in cold weather.

How to Clean the MBR Membrane?

Once the MBR membrane is polluted, the membrane pores will be clogged, and the flux will drop. Therefore, we must clean the MBR membrane module to restore the membrane flux and extend its life span. The following is a detailed explanation of how to clean the MBR membrane.
