Membrane Bioreactor Wastewater Treatment System

Membrane Bioreactor Wastewater Treatment Plant for Municipal Waste Water
 
Product Description of Wastewater Treatment System

Membrane Bioreactor (MBR) Wastewater treatment technology uses a membrane or a ‘perm-selective’ membrane such as a microfiltration or ultrafiltration. The membrane is porous and allows the passage of water and dissolved solids while restricting the passage of solid materials on the other side of the membrane.

MBR Membrane Bioreactor MBR is a new type of high efficiency wastewater treatment process combining high efficiency membrane separation technology with traditional fully activated sludge method, which replaces the secondary sedimentation tank in the traditional activated sludge method with membrane modules to retain a large number of microbial flora in the biological system, which leads to an increase in the number of microbial flora and biological species in the system and improves the wastewater treatment capacity and efficiency. The effluent quality and volumetric load of the system are greatly improved, and the effluent can be reused as medium water.

How Does Membrane Bioreactor Work?

Membrane bioreactor wastewater treatment combines the conventional biological process, i.e., activated sludge, with the membrane filtration technology, Just like the sewage treatment plant, the traditional classical treatment process is Pretreatment ( Bar Screen)—Primary Sedimentation—Anaerobic treatment—-Aerobic tank—-Secondary Sedimentation tank, and in this treatment process “ Sedimentation tank “ should be very big and the output water quality not stable because of some Activated sludge will be outflowed together with permeate. And the MBR Technology use Submerged MBR Membrane replace the big Sedimentation tank, the MLSS (which is the bacterial concentration in the reactor basin ) will be higher, and as the reflux pump designed Q= 2 times of output, from MBR Tank to Anaerobic tank, then whole system treatment efficiency will be higher and output quality will be better.

Advantages of Wastewater Treatment System

The MBR process has a number of significant advantages over the conventional activated sludge method, such as:

In the MBR process, the activated sludge concentration is generally controlled at 7000 to 18000 mg/L. This is equivalent to five times the sludge concentration of the conventional sludge system. As a result, the biochemical treatment efficiency of the MBR process is greatly improved and the floor space of the reaction tank can be saved by 60%. In addition, since the membrane modules replace the deep treatment processes such as clarification and filtration, these equipment can be eliminated, thus saving the floor space of the entire wastewater treatment plant.

Generally speaking, wastewater treated by MBR process has almost no detectable suspended matter and turbidity less than 1. Combining biochemical treatment with membrane separation technology, MBR produced water can be used for almost all non-potable reuse applications - agricultural green irrigation, boiler make-up water (RO pretreatment) and industrial process water. The MBR process is also effective in reducing the presence of pathogenic bacteria, such as E. coli and Cryptosporidium spp.

By removing treatment units such as primary sedimentation tanks and clarifiers, MBR is integrated into an integrated process for operation. No sludge settling or chemical dosing (e.g., flocculants and coagulants) is required, thus also eliminating the chemical dosing system required in the conventional case. In addition, by eliminating the sludge settling tank, which is greatly affected by sludge concentration and properties, the number of sampling and analysis tests can be taken. Overall, the MBR process can effectively reduce the workload, while the MBR process is easy to operate and stable in operation, so many MBR projects are operated by part-time technical service personnel who operate the MBR system via remote and on-site control systems.

Benefits of Containerized Water Treatment Plant

1. The hydraulic retention time is separated from the sludge age. The MBR membrane technology can intercept all microorganisms in the water, realize the separation of the hydraulic retention time and the sludge age, make the operation control more flexible, and make it possible to extend the sludge age. This is conducive to the growth and reproduction of slow-proliferating nitrifying bacteria, and the denitrification efficiency is greatly improved. At the same time, because the system has a long sludge age, the amount of excess sludge produced is very small.

2. The effluent quality is higher than that of traditional biochemical processes. Membrane technology can not only trap microorganisms in the water, but also trap some of the insoluble pollutants of macromolecules, prolong the residence time of pollutants in the reactor, and increase the removal rate of refractory pollutants. At the same time, because the mud age is long, the denitrification effect is good, and the effluent is basically free of SS, the effluent quality of MBR is better than that of the traditional process.

3. Strong impact resistance, MBR sludge load is generally about 0.1~0.2kgCOD/(kgVSS·d), and the volume load can reach about several thousand grams.

4. It can effectively reduce the concentration of pollutants. As a biochemical treatment process, the MBR membrane can convert organic matter into carbon dioxide and water, and nitrogen pollutants can be converted into nitrogen. It can also reduce the conductivity of raw water, which makes the subsequent membrane treatment process load a lot Alleviate, prolong the life of the membrane, increase the water production rate, and reduce the concentration of the concentrated solution.

5. Small footprint. Due to the high rejection rate of the membrane system, the reactor can maintain a high concentration of sludge, which is usually 3-5 times that of the traditional activated sludge method. The high sludge concentration makes the volume of the reactor relatively large. The traditional craft is much smaller, coupled with the high-efficiency deep-water oxygen supply form, the area of the biochemical part is much smaller than that of the traditional craft.

6. The remaining sludge output of this process is low, which reduces the cost of sludge treatment.

7. Convenient operation and management, easy to realize automatic control
