SBR SEWAGE TREATMENTATMENT
Wastewater treatment by Sequential Batch Reactor (SBR) is a fill-and-drain activated sludge system for wastewater treatment. In this wastewater treatment system, the wastewater is transferred to a single cut-off reactor in order the undesirable components to be removed and then the effluent is discharged. Balancing, aeration and clarification can all be achieved by applying a single SBR unit. To optimize system performance, two or more SBRs are embedded in the sequence of operations. SBR systems have been successfully used to treat municipal and industrial wastewater. These methods have a unique role in the treatment of wastewater with alternating current or low current.
Processes such as the SBR are not a method that has progressed to the present stage. Between the years 1914 to 1920, various full and empty systems were operating. Due to the development of new devices and technologies, the interest in SBR and SSB systems was revived in the late 1950s and early 1960s. The reason was the development of new devices and technologies. Advances in aeration equipment and control systems allowed the SBR and SSB systems to be flourished. That these systems could compete successfully with the conventional activated sludge system.

Comparison of SBR wastewater treatment system with activated sludge system
The process of the SBR and SSB wastewater treatment unit and conventional activated sludge are both the same. Report in 1983 by the US Environmental Protection Agency stated the following:
SBR and SSB wastewater treatment is not different from conventional activated sludge system. Except that this system works with time instead of space.
The SBR and SSB wastewater treatment systems operate with a time sequence control. That performs balancing, biological treatment and secondary clarification operations in a pond. This model of reactors practically includes primary clarification.
In a conventional activated sludge system, the above processes must each take place in a separate tank.
In addition to the SBR and SSB systems, they also use the WET-LAND system to improve purification. That system is also designed and implemented based on its scientific principles.
