IWAT - Model SBR -Sequencing Batch Reaktor

Developed with the collaboration of Prof. Otto R. Wilderer at the TU Munich, this method utilizes a single reactor tank to sequentially carry out different cleaning phases — Fill, React, Settle, Decant, and Empty.

A significant advantage of this system is phase separation, where the sludge settles at the bottom, allowing clear water to be drawn off from the top. This is particularly advantageous for achieving specific water quality goals.

Despite its many advantages, such as high adaptability to various industrial requirements and effective response to load fluctuations, the SBR process requires comparatively more space, which can be considered a drawback, especially in areas where space is limited.

These characteristics make the SBR system a valuable yet space-demanding solution for complex industrial wastewater problems.

Organic substances
such as hydrocarbons, which are biodegraded by ventilation and microorganisms.?

Nitrogen compounds
Ammonia, nitrates, and nitrites, which are converted through nitrification and denitrification.

Pathogenic microorganisms
due to the controlled environmental conditions and the oxygen supply during the reaction phase in the tank.

Suspended solids & sediments
which separate during the settling phase and sink to the bottom, allowing clear water to be drawn off from the top.
