This device doses small amounts of a 3g/l ‐concentration chlorine dioxide (ClO2)
solution into the flow of demineralised water produced by the machine.
The chlorine dioxide dosing system is made of two separated containers, the one
housing the electronic control unit and the other the dosing pump and the waterflow
components. Containers are connected through an umbilical cable .
The control unit comprises a microprocessor system which sets the correct amount of
chlorine dioxide to be injected on the basis of the produced water flow measured by a
flowmeter and of the user's programming. It is equipped with display with LED to
monitor the operation and program dosing phases by means of two buttons. It also
allows the control of the remaining validity time of the chlorine dioxide solution. An
acoustic signal too warns of the expiration of the validity time.
The container housing the peristaltic pump which carries out the microdosage also
houses the flowmeter and the injection system, besides being also the support of the
bottle containing the chlorine dioxide concentrated solution.
The water flow produced by reverse osmosis is intercepted during its flow to the
storage tank by the flowmeter which measures its quantity. The flowmeter sends the
information to the control unit which starts the pump for a time suitable to achieve the
correct dosing.
The chlorine dioxide is hence injected into the demineralised water flow through a non‐
return valve.
