The control provides an appropriate amount of diluting water in the mixer

Bello Zon ® chlorite into their respective measuring vessels until the level
switches in the vessels trigger. The control then empties the acid and
chlorite into the mixer vessel. After a defined reaction time has elapsed,
the control fills the mixer vessel with water until the vessel's level switch
triggers. This ensures that the produced solution is well mixed.
Thereupon, the control empties the content of the mixer vessel into the
