SBR technology is a type of wastewater treatment system that combines the concept of batch and continuous processes in one reactor. SBRs are designed to optimize the operation, control, and sequencing of reaction tanks in an automated process that is capable of treating a variety of liquid wastes with high efficiency.
SBR systems use biological or chemical methods to convert wastewater into an acceptable effluent quality suitable for discharge or reuse. SBRs are most commonly used to treat municipal wastewater, industrial wastewater, and domestic sewage that contains high levels of pollutants such as nitrogen and phosphorus.
SBR systems use a sequential or “batch” process in which the reaction tanks are filled with wastewater. The SBR then cycles through the process steps of filling, reaction, settling, decanting, and idling. The SBR finds and measures the optimum conditions for each step to optimize the pollutant removal efficiency.

SBR technology offers a variety of benefits ranging from the reduced total cost of ownership to improved effluent quality.
SBR systems require less space than traditional wastewater treatment systems, and they can be more easily installed in existing infrastructure or integrated into new plant designs. SBRs also allow for more efficient plant operation and maintenance.
SBR technology is highly effective at treating wastewater, and SBR systems are capable of achieving very high effluent quality. SBRs also feature conditioned aeration, which eliminates the need for additional treatment processes and reduces the total cost of ownership. SBR systems also feature superior control capabilities that allow for a more efficient operation.
SBR systems are easy to operate and require less maintenance than traditional wastewater treatment systems. They can also be operated at lower temperatures than traditional systems, which reduces energy consumption and overall operating costs. SBRs also often require fewer chemicals for operation, resulting in lower chemical usage and costs.
SBRs are also automated, which means that they require fewer personnel for operation and monitoring. SBRs can achieve high levels of pollutant removal efficiency even in variable load conditions.
The basic principles of biological degradation processes were developed in the early 1900s. Several of these systems were in operation by the 1910s with the first fill-and-draw process used in the United Kingdom. Although the treatment process could achieve good effluent quality, there were many operational issues, which eventually favored the development of the continuous flow type of systems.
Improvements in equipment and technology, especially in aeration devices and computer control systems, have made SBRs a viable choice again. Since then, SBRs are being used successfully to treat both municipal and industrial wastewaters, particularly in areas characterized by low or varying flow patterns. Small municipalities, resorts, and several industries, including food and beverage, pulp and paper, and textiles, are using SBRs as practical wastewater treatment alternatives.
SBRs aren’t only being used in small capacity systems, however. Over the last few decades, SBRs are being used by large cities as well. The largest SBR facility in the world is in Kunming, China, and has 300 MLD/80 MGD capacity.
Since the beginning of our company, we’re consistently asked when SBR would be available in Transcend Design Generator. We take those requests seriously and are happy to note that SBR is now included as an available technology within TDG!
