The operation of the MBR flat membrane used in the general membrane bioreactor process is still very stable, and it is not necessary to take the membrane out of the membrane module for maintenance and protection.
However, if there is a serious operation error, such as the mbr flat sheet membrane is scratched by large particles, it may cause serious pollution and damage to the MBR flat sheet membrane.
Despite repeated immersion and cleaning, the quality of the effluent still fails to meet the requirements. At this time, the membrane needs to be taken out of the membrane module for replacement.
1. Check whether the flow rate of each membrane module changes significantly under a specific pressure difference. If the flow rate is lower than 20% of the designed flow rate, it is judged as a damaged component.
2. Block the module, lift the membrane module out of the water, and the highest part of the MBR flat membrane module can be exposed to the water surface, or the water level can be lowered to the upper part of the module to reveal the water surface, and other membrane modules can operate normally.
3. Separate the branch pipe and water collection pipe in the membrane module, take out the stainless steel pressure plate around, take out the mbr reactor one by one, check the reason, and protect it.
Generally speaking, MBR flat sheet membrane is less likely to be damaged, and in most cases, some areas are damaged. At this time, the damaged membrane needs to be replaced, and the entire MBR flat membrane only needs to be disassembled.
But take special care not to lose any barrier sheets, sealing sheets and other parts. Find the bad MBR flat diaphragm and replace it with a new one.
Put the repaired MBR flat membrane back into the membrane assembly, connect each pipeline, adjust the valve, wait for the water level to reach the operating state, and then it can be restarted.
With the development of scientific skills, some new processes have been applied to the activated sludge process. As an emerging material science, membrane treatment technology has been widely used in the water treatment industry.
In the drinking water industry, microfiltration, ultrafiltration, nanofiltration, reverse osmosis and other clean water technologies have been achieved using membrane materials of different pore sizes, and they have also been used in clean water equipment in ordinary people's homes.
In the sewage water treatment industry, with the gradual improvement of sewage water treatment effluent quality under strict specifications, MBR flat membrane modules that reliable disinfectant supplier provides have been gradually applied to sewage water treatment.
Some sewage plants with high water quality requirements use MBR flat membrane bioreactor as part of the activated sludge treatment process, which improves the sewage water treatment effect to a certain extent.
Because of the existence of the MBR flat membrane module, the solid-liquid separation capability of the system is greatly improved, and the effluent quality and volumetric load of the MBR flat membrane bioreactor have been greatly improved.
The water quality standard after membrane treatment is high, and through disinfection, high-quality reclaimed water with good water quality and biosafety is formed, which can be directly used as a new water source.
Because of the filtration effect of the membrane, the microorganisms are completely trapped in the MBR flat membrane bioreactor, and the HRT is completely separated from the activated sludge age. The MBR flat membrane eliminates the sludge swelling problem of the traditional activated sludge method.
