Following a primary physical separation treatment - if necessary - a certain flow of waste is introduced into the tank.

The reaction cell rotates around its axis and is partially immersed in the wastewater so as to allow natural oxygenation of the bacterial colony. This technique allows to avoid the use of compressors and therefore there isn't any aerosol effect.

With the implementation - as soon as the waste water flows into the reactor - the bacterial film begins to develop. The time needed to be fully operational depends on the load of the waste water and other environmental variables such as temperature.

The output flow may need standard separation methods from the process sludges - such as decanting or filtration - in case the residual suspended solids exceed the legal values.
