Membrane bio reactor of wastewater treatment (WWT)

This is also known as MBR technology for the waste water recovery and its reuse for usage. In this reactor the waste water moves towards the bio reactor, in this bio reactor different harmful chemicals are present. Then after this there is a membrane is present that is involved in removing waste from water in easy way and supply clean water in better way for reuse. This method is the improved model of the conventional activated sludge process for cleaning waste water. In this reactor the traditional secondary clarifier is replaced by the help of membrane unit. That contains different chemicals.

During the process harmful materials are mixed with membrane chemicals, and water become pure. This technology is based on the biological treatment that is followed by membrane separation. The membrane that is present in this reactor is involved in effectively separate biomass from the water and improve quality of effluent, and make it easy for reuse. In the membrane part there are about five billion microscopic pores are present on the surface, these pores form a barrier for impurities and just allowing pure water to pass through it (LI & ZHANG, 2010).

According to the author Fangang (2017) he has given some important information about the new latest technology in the membrane bioreactors that is fouling. In this article the author has presented deep and comprehensive research on the new technology in the membrane bio reactor. It can be seen that from the previous researches the membrane fouling is one of the most important challenge for these reactors.

In this article deep analysis has been performed on fouling mechanism and improve this technology by changing control strategies of fouling membrane. There is some improvement has been done on the fouling control strategies. The results shows that it is extremely necessary that there is complete information about dynamic changes in membrane foulants because it will help to improve this technology in better way. A complete literature review has been presented in this article about fouling membrane (Meng, et al., 2017).

In this article the author Ali Raza (2011) was involved in giving demonstration about modeling of membrane bio reactor that can be done by artificial neural network. This membrane is involve in dissolving different solids and also various organic loading rates. For that case a complete feed forward neutral network is used that is trained by batch back propagation algorithm. For training the network a complete set of 193 operational data from different waste water is used with MSBR. The results shows that there is comprehensive mixing of different particles like OLR, TDS, COD in the waste water is removed through this membrane. In such conditions it can be seen that the average effluent COD concentration is meeting the discharge limit in efficient way (Pendashteh, et al., 2011).

In this article the author Cornelissen was presenting an innovative Osmotic membrane bioreactor for the reuse of water. This Osmotic membrane bio reactor is more efficient than ordinary bio reactor. A perfect analysis has been done in this article for this innovative technology. This technology is still under development due to some problems in the system. This research mainly focus on FO membrane fouling and its performance has been evaluated through the help of different activated sludge process.

In this article complete investigation has been done on the laboratory scale by just increasing the temperature so viscosity can be decreased. The results shows that there is some improvements need to be done for enhancing the performance of membrane. It can be seen that for economic assessment minimum flux that is required is 15 at 0.5 molar of sodium chloride for reducing the cost (Cornelissen, et al., 2011).

In this article the author Nguyen has presented new technology for the membrane bio reactor. In this case there is use of innovative sponge-based moving bed osmotic membrane hybrid system is used through the use of new class for solving wastewater treatment issue in proper way. This can be done through combining two membranes with each other that include sponge based moving bed combine with osmotic membrane bioreactor that is also called hybrid system.

This system has been investigated in detail with the help of Triton X-114 surfactant mixed with magnesium chloride. This system is compared with the other system and it is involved in removing more particles from the water due to its thick bio film layer present on sponge carrier. This is because during waste water treatment there is less membrane fouling was observed in proper way and that is not proper method to remove waste from water because it was not cost effective.

There is must need of perfect system that can easily solve this issue. For this some experiments has been performed to solve this issue in perfect way. This shows that in this hybrid system there is need of water flux of 10.5 and low salt value was achieved in 90 days. The efficiency of this system is almost 100% because of these layers. The results shows that if the system is using Magnesium chloride mixed with Triton so it can easily able to remove particles from water in effective way (Nguyen, et al., 2016).

According to the author pen 2014, he has present important model for methane biohydroxylation. For this an improved and innovative membrane bioreactor is used that can easily solve the issue. It can be seen that this methane biohydroxylation was done for the first time in any membrane bio reactor. In this article there is complete study about the membrane bio reactor has been presented in detail.

For analysis a complete innovative membrane bio reactors was mixed with bioreactors and also with the two main bio reactors. In this article the reproducibility and feasibility of biohydroxylation was tested in proper way in the laboratory. The results shows that the productivity has been reached with this type of membrane bio reactor is about 75 mg methanol. It can be seen that this value is quite higher than previous models. The main advantage of this MBR was explosive gas mixture can be easily reduced (Pen, et al., 2014).
