2 About this system
The Bello Zon ® CDLb chlorine dioxide generating and metering system is
designed for drinking water treatment - especially in respect of water disin‐
fection using chlorine dioxide.
The control provides an appropriate amount of diluting water in the mixer
vessel and mixes it with precisely measured quantities of hydrochloric acid
and sodium chlorite, which are metered using two measuring vessels and
two metering pumps. This creates a ClO
2
solution with a concentration of 2
g/l (CDLb 6: 1 g/l). Thanks to the lower concentration relative to other pro‐
cesses, the process is particularly safe.
The produced ClO
2
solution flows into the external pre-storage module,
from which it can be dosed using the metering pumps.
