Membrane bioreactor (MBR) Wastewater Treatment Plant Water Purifier
 
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.

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.

Features of Containerized Water Treatment Plant

According to a large number of practical studies, when the concentration of dissolved oxygen reaches 0.8mg/L, the removal rate of TN is higher, reaching about 86%. As the concentration of dissolved oxygen continues to increase, the removal rate will decrease. Therefore, it is shown that when the concentration of dissolved oxygen is maintained at 0.8-1.2mg/L, high-efficiency F/M and COD/N will promote simultaneous nitrification and denitrification.

Biological denitrification process is divided into nitrification and denitrification. When NO2- is directly used for nitrification reaction, it is directly passed through NO2- for biological denitrification. The chemical principle applied in this process is short-cut nitrification-denitrification. The applied principle of denitrification is to control the entire nitrification process in the nitrite stage to prevent the conversion of nitrite to nitrate.

MBR process is usually combined with A/O biological denitrification process, so that a better denitrification effect can be achieved. The key part is to strictly control the nitrification process at the nitrite stage. In related studies, by adopting the A/O-MBR denitrification process for wastewater treatment, it is only necessary to control the dissolved oxygen in the aerobic section at 0.5 mg/L, and the removal rate of NH4--N and the cumulative rate of NO2--N are both As high as more than ninety percent.

The anaerobic ammonia oxidation processes currently applied include SHARON-ANAMOX and CANON. Many researchers apply CANON process in MBR. In the process of wastewater treatment, the hydraulic retention time is shortened to a certain extent, and ammonia oxidizing bacteria can be quickly enriched at room temperature, and the chemical oxygen demand and total nitrogen content can be removed at the same time, and the removal efficiency is also relatively high.

Relevant researchers found that MBR does not effectively improve the removal efficiency compared with the traditional phosphorus removal process in wastewater treatment. When the anaerobic environment is increased, the removal efficiency can be increased by about 50%.

The batch-type membrane bioreactor treatment process is mainly through the effective control of aeration time to realize the anoxic and aerobic conversion in the time series. This removal process does not require the use of a reflux device for the mixed liquid, which can effectively reduce the difficulty of operation and the cost of investment. In addition, the phosphorus removal efficiency is relatively high, and the removal efficiency of industrial wastewater can be as high as 95%.

The application of MBR in wastewater treatment can rely on its membrane retention effect to promote nitrifying bacteria to rapidly multiply and survive in the MBR under short reaction conditions, and then carry out nitrogen and phosphorus removal, and its removal effect is also ideal.

 
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
