SBR (Sequential Batch Reactor) is a system for the biological treatment of wastewater. In contrast to conventional activated sludge processes, where wastewater undergoes treatment by passing through a series of tanks, the SBR method involves conducting different steps sequentially in the same tank.

As the reactors are filled on a batch-by-batch basis, several SBR tanks and/or an influent buffer tank are required to treat wastewater continuously. On the other hand, there is no need for the recirculation equipment that typically accompanies continuous systems, and the cleaning performance can be flexibly and perfectly adapted to requirements.

The typical steps involved in the process are:

• Fill (mixed or aerated)
• Reaction: aeration or mixing
• Sedimentation
• Decantation: extraction of the clean water

Special decanter. The WABAG swivel-joint decanter has been designed by drawing on a wealth of experience from various projects and is produced in-house by us. The model is in use at several plants. Its defining features include a maintenance-free stainless steel swivel joint and optimized hydraulics.

The CYCLOPUR® process is extremely flexible and suitable for all types of wastewater and plant capacities.
