There will be many problems when using MBR membrane module, so what are the main problems of MBR membrane module? Next, let's take a look at the main problems of MBR membrane module.
1. Membrane fouling
In the wastewater reuse project using membrane technology, the diaphragm is the component with the highest technical content and the greatest value. The longer the diaphragm is used, the better. From the actual production situation, the pollution of organic matter and inorganic salt to the membrane exists, and it is obvious. In general, inorganic contamination is closely related to microbial contamination, and microbial contamination of the membrane is difficult to clean and remove. How to effectively reduce membrane fouling is the most difficult problem to be solved in the next step.
2. Membrane fouling and broken wire
How to reduce the deposition of metal ions and the chemical modification of the film to make it brittle is also an urgent problem to be solved. The mechanism of some microaccumulation is currently unclear. According to the water quality of the target water, it is very important to formulate and adopt different cleaning agent formulas, make supplementary analysis of related projects, and accurately judge the influencing factors to guide the operation of the membrane.
3. Smooth operation of pre-processing
In the system design and actual production process, the water quality characteristics of petrochemical industrial wastewater must be fully considered to avoid high concentration of harmful substances impacting the membrane and causing membrane damage. Ensure the smooth operation of the pre-treatment, improve the impact resistance, and ensure the long-term stable operation of the MBR membrane module system.
