The sequencing batch reactor process ( SBR ) involves a single complete mix type reactor in which aeration takes place followed by clarification, whence the designation "sequential". Sludge settles when aeration is shut down and a drainage mechanism used to draw off the supernatant liquor.
A sequencing batch reactor (SBR) treats wastewater in optimized batches. It uses proven biological processes to remove contaminants. The result is exceptional performance with minimal energy consumption. Our range of Rewatec SBR systems takes these design principles and hones them for your requirements.

The Alfa Laval AS-H Sequencing Batch Reactor wastewater system (also called sequential batch reactor or SBR) is tailored specifically for your plant's needs. This simple, all-in-one solution performs the core activated sludge process in one reactor, eliminating the need for separate treatment tanks for each process step.
The Sequencing Batch Reactor (SBR) is a different configuration of the conventional activated sludge systems, in which the process can be operated in batches, where the different conditions are all achieved in the same reactor but at different times. The treatment consists of a cycle of five stages: fill, react, settle, draw and idle.
SBR operation The operating cycle of all SBR processes have, at the least, periods of the following phases: • Fill • Aerate • Settle • Decant Additional phases that could also be implemented include anoxic mix and idle. Figure 1. This figure illustrates four-hour SBR cycle timings
Sequencing batch reactor (SBR) 1. Facultative Lagoon. A facultative lagoon design uses a giant lagoon for aeration. The design includes a system of constructed ponds to polish the water. It's the most common design for treatment plants because it's the easiest to set up. 2. Activated Sludge. Activated sludge designs are also common. In this ...
Rewatec SBR systems combine treatment and clarification in a single tank, giving you a streamlined design that optimizes your equipment and operating costs. Available models No two projects are the same. That is why we offer a range of Rewatec SBR systems, each designed according to your unique wastewater treatment needs and preferences.
Flexible configurations Process flexibility – Complete Mix-Activated Sludge, SBR, or MBR Continuous or batch process Process guarantees available Available in portable shop-fabricated rectangular, or circular field erected designs Package plants provide a "plug and play" solution for your wastewater treatment needs.
8.7 SBR Processes in Wastewater Plants, Larrea et al (2007) 9. Conclusion Glossary Bibliography Biographical Sketches Summary Sequencing batch reactor (SBR) is a fill-and-draw activated sludge treatment system. Although the processes involved in SBR are identical to the conventional activated sludge process, SBR is compact and time oriented ...
Older wastewater treatment facilities can be retrofitted to an SBR because the basins are already present. Wastewater discharge permits are becoming more stringent and SBRs offer a cost-effective way to achieve lower effluent limits. Note that discharge limits that require a greater degree of treatment may necessitate the addition of a
A sequencing batch reactor (SBR) is an activated sludge biological treatment process that is applicable to treatment -of municipal and industrial wastewater for small to medium flowrat.es, (0 to 5 mgd) . ... Transenviro chooses to' design SBR systems in this manner to avoid potential settling problems that may occur in reactors without ...
BIO-BATCH™ SBR is a process developed by Napier-Reid in which continuous inflow and treatment is accommodated through alternating react, settle, and decant sequences in SBR trains. Each train, through a typically operating cycle of three to five hours, provides all of the processes of activated sludge treatment in one basin.
The OMNIPAC® SBR Field-Erected Treatment plant is a cost-effective, proven advanced wastewater treatment system utilizing a DAVCO™ pre-engineered and factory built steel circular tank design that includes Evoqua's SBR systems with Jet Tech technology.
SBR Aerobic Treatment Plants is an authorized seller of Aquarobic ® advanced sequencing batch reactor aerobic waste water treatment plants. Aquarobic ® waste water treatment plants provide the perfect alternative to the common septic system, where such a system would be unsuitable for the environment or otherwise prohibited. Each Aquarobic ® system is specifically tailored and custom built ...
The design configurations of the ICEAS and the SBR are otherwise very similar. Description of a Wastewater Treatment Plant Using an SBR A typical process flow schematic for a municipal wastewater treatment plant using an SBR is shown in Figure 1. Influent wastewater generally passes through screens and grit removal prior to the SBR.
With the ADI® SBR, process events are separated by time rather than space, making it easy for operators to add, lengthen, shorten, or alter the sequence of the different events to achieve a desired process modification. The technology is suited for all types of applications, and can be used as a stand-alone process or to polish anaerobic effluent.
The Sequencing Batch Reactor – SBR is a single reactor, uses "fill and draw" process for treating wastewater with activated sludge and has been around since the 1920s. In comparison with...
A baffle wall may be used in the ICEAS to buffer this continuous inflow. The design configurations of the ICEAS and the SBR are otherwise very similar. Description of a Wastewater Treatment Plant Using an SBR A typical process flow schematic for a municipal wastewater treatment plant using an SBR is shown in Figure 1.
The Defense Distribution Susquehanna Installation in New Cumberland, Pennsylvania, serves as a primary distribution point for all branches of the U.S. Armed Services and other federal agencies in the eastern U.S. Covering 851 acres, the installation included a wastewater treatment plant built in the 1960s that provided service to more than ...
The previous treatment process utilized an aeration lagoon, followed by a series of facultative lagoons. With a total project cost of $4.7 million, the new SBR system utilizes the existing aeration lagoon for equalization and another lagoon cell for sludge storage, which reduces the cost of the project for the City and provides more operational flexibility.

However, processes that take place inside wastewater treatment plants (WWTP) are highly complex in nature, therefore it is difficult to design an efficient, optimal control system. The problem regarding biochemical reactions inside Sequential Batch Reactor (SBR) is analyzed in this paper and the optimization problem is defined.
