SBR system It consists only of biological treatment processes. It is a sequence reactor process. It provides the highest purification efficiency in single biological systems. It operates as a batch reactor, eliminating the inefficiencies of continuous processes. The batch reactor 0 is an excellent reactor that provides purification. It is a single reactor in which all biological treatment stages occur sequentially. The completed biological operation is divided into cycles, each cycle lasting 4-6 hours, during which time all purifications take place. These cycles are as follows:

• Air filling (F/A)
• Settlement
• Unloading
