Batch systems are physical-chemical systems carrying out the treatment in a discontinuous way, that is with single and following operations, in a unique reactor with fixed volume, according to a proper succession.

“Batch” working is preferred to “constant” treatment or to the disposal, when:
- The daily volumes to be treated are very small.
- The nature of the effluents and the targets of the purification require the employ of a specific process on particular fractions of waste water (e. g. treatment of cadmium, nitrites,…).
- The waste water to be treated is subject to considerable quantity and quality variations.
