1. Initially, the production process is terminated.
2. The operator starts the production in the menu.
3. The solenoid valve opens and water flows into the reaction
tank.
4. The floater in the reaction tank reaches level K1. The solenoid
valve closes. The HCl dosing pump starts and HCl flows into
the reaction tank.
5. The floater in the reaction tank reaches level K2. The HCl
dosing pump stops. The NaClO
2
dosing pump starts and
NaClO
2
flows into the reaction tank.
6. The floater in the reaction tank reaches level K3. The NaClO
2
dosing pump stops. The chemical reaction begins. Reaction
time: 15 minutes.
7. The reaction time has elapsed. The solenoid valve opens and
water flows into the reaction tank.
8. The floater in the reaction tank reaches level K4. The reaction
tank now contains the ready-to-use ClO
2
solution.
9. The position of the floater in the internal batch tank is
checked.
– If the internal batch tank is full (floater is above level K5), the
process continues with step 10.
– If the internal batch tank is empty (floater is below level K5),
the solenoid valve stays open. The process continues with
step 13.
10. The solenoid valve closes.
11. The ready-to-use ClO
2
solution remains in the reaction tank.
The process waits for the content of the internal batch tank to
be discharged by the ClO
2
dosing pump.
12. The floater in the internal batch tank falls below level K5. The
solenoid valve opens with delay and water flows into the
reaction tank.
13. The level in the reaction tank rises until the reaction tank
overflows. Due to the siphon effect, the batch starts to flow
through a pipe in the middle of the reaction tank into the
internal batch tank.
14. The floater in the internal batch tank rises above level K5. The
solenoid valve closes. The content of the reaction tank is
discharged into the internal batch tank.
15. The floater in the reaction tank reaches level K1. The waiting
time starts.
16. The waiting time has elapsed. The production mode is
checked:
– If the production runs continuously, the process starts again
at step 3.
– If the number of batches to be produced is reached, the
process terminates (step 1).
