Sequence Batch Reactors of wastewater treatment (WWT)

It can be seen that through the use of activated sludge system other unit processes are completed through use of separate tanks. This sequencing batch reactor is the new modified model that is used for treatment of waste water in proper way. This system is more efficient than the activated sludge system because it is involve in performing equalization. This system also uses timed control sequence for secondary clarification of waste water with the help of single tank.

This system is useful in those areas where there is limited amount of area is available. The main advantage of this process is that all phases and steps are carried out in the same tank. This system is the modified model of the activated sludge system. In that case the waste water is moved towards the single batch reactors and all waste particles are removed easily. There are some major advantages of this system. The sequence batch reactor is controllable and contain quiescent settling process. It can be seen that there is minimum footprint during process. It has the ability to remove more nutrients from water. The efficiency of about 90%.

According to the author Ali, he has presented some important concepts regarding sequence batch reactor. For this there is need of improved sludge by just introducing two stage settling sequencing batch reactor. From the different researches it can be seen that sludge settleability is one of the main drawback in sequencing batch reactor.

            The main purpose of this study is to introduce a unique method that is consisting of two stage settling sequencing batch reactor separated by anoxic stage. In this article there is comprehensive work has been done on this technology, and this technology is compared with the other normal operating sequence batch reactor that are operated at same cycle. Then after this the results shows that there is some important improvement can be seen in sludge settleability and removal of unwanted particles from water.

The best part in this model is that through this different chemical efficiency has been improved than the other system. In the NOSBR reactor there is huge amount of bacteria is present in after three months of operation. The results shows that the efficiency of the removal of waste water has been improved through the use of two stage settling sequence. It can be seen that there is morphological characteristics are found in the two stage SBR (Alattabi, et al., 2017).

In this article the author Haibo has presented some innovative biological process that can be used for treatment of removing waste from water. It can be seen that in the past the coking waste water can be done through the use of biofilm system that is made up of simple anoxic bioreactor. For that reactor there is a need to improve efficiency for removal of organic compounds that are present in water. For that case anoxic bio reactor is used to remove organic compounds through the use of anoxic process.

 Also there is aerobic bioreactor present that is used to check the feasibility of the system. From the results it can be seen that through improved biological process the efficiency of waste water removal and other compounds from water is increased. There are some biological compounds that are used in this reactor to solve the issue of water treatment in effective way. Ammonia oxidation and nitrate accumulation ratio in the reactor is maintain at 85% for achieving the required efficiency.

For the analysis there is a use of gas chromatography spectrometry analysis is used. According to the results there is still a need of further modification in the system. This is because through this waste water treatment system can be increased through the use of SBR (Li, Cao, Li, Zhang, & Liu., 2010).

According to the author Lei 2014, he has presented important work regarding the innovation in the SBR system. This can be done through the use of real time controlled three stage SBR system. A real time sequence batch reactor is mainly consist of pretreating, nitritation and anaerobic ammonium oxidation.

There is quite huge concentration of ammonia can be seen during process. The results shows that after 40 days there is increase in efficiency in the nitritation stage of about 90%. For that case there use of continuous filling process because it will help to reduce nitrate inhibition (Miao, et al., 2014)
