SBR Package Units

The Sequencing Batch Reactor (SBR) is an activated sludge system in which aeration and sedimentation processes occur in the same tank, unlike continuous systems. Wastewater is fed into the reactor tank, treated, and discharged. The SBR system consists of five steps: 1) filling, 2) aeration, 3) sedimentation, 4) discharge, and 5) removal of excessive sludge (if needed). SBR systems act as a balance tank, adapting to fluctuating pollution loads and raw water quantities. They occupy less area compared to classic continuous systems. The duration and frequency of the five steps can be adjusted as needed for nitrogen and phosphorus removal. This system is cost-effective as it does not require a secondary settling sedimentation tank, which is a requirement for classic systems, as sedimentation is carried out in the same tank. Reactors can be produced as modular types or from reinforced concrete, making them suitable for all required capacities.
