TRO is mainly used to detect the chloride ion content of electrolyzed seawater in the electrolysis unit during the ballasting process. During the normal ballasting process of the system, the TRO reading should be between 5-9.5mg/L. During the discharge process, TRO detects residual chlorine in the seawater in the pipeline, and the TRO reading should be less than 0.1mg/L.

2. Preparation of TRO reagent
There are two types of TRO detection reagents, buffer and indicator. A one-year set includes one bottle of buffer and four bottles of indicators. Once formulated, buffers and indicators have a shelf life of one year and three months respectively. Since both reagents have shelf life issues, they are generally supplied in dry powder form and must be prepared in advance before use.
– Preparation of Buffer buffer
(1) Take out the buffer, as shown in the figure:
(2) Put an appropriate amount of distilled water into the buffer bottle, the water is about 9/10 of the bottle, cover it and shake well.
– Preparation of indicator
(1) Take out the DPD powder, indicator, and two bottles as shown in the picture;
(2) Open the lid and pour the DPD powder into the indicator;
(3) Fill the indicator (Indicator) in the picture above with an appropriate amount of distilled water. The water should be about 9/10 of the bottle. Cover the lid and shake well.
Note: Each mixed indicator reagent will last for 90 days if stored in a dedicated cooling box.
3. Basic operations of TRO
Before starting the ballast water treatment system, you need to install detection reagents on the TRO and open the corresponding sampling valve.
After turning on the system, TRO will automatically start based on the operating mode of the system.
Inject reagents: press PRIME + “, for each initial run,
This operation should be performed once, and TRO will automatically perform a dosing operation.
Traffic check:
a) Press the “service” button, wait for the screen to display “HOLd”, and press the “mode/exit” button;
b) The screen displays “FLOW” and the number “0” indicating flow rate, press the “▲” or “▼” button;
c) The system will automatically detect the flow rate and display the corresponding value on the screen.
If “Good” is displayed at the end, it indicates that the flow rate is appropriate and no adjustment is needed. Press “OK” and the system will enter the detection program.
The test will have three results: HI, GOOD, LO
If the flow rate is still not normal after adjustment, please repeat the above operations.
4. Troubleshooting related to residual chlorine analyzer (TRO)
In case of failure, it will be in TR. A fault message appears on the display. If RGNTTRO does not take out the reagent, it needs to be re-added manually to ensure transparency.
The medicine tube is filled with medicine.
For other fault types, please refer to operating instructions P.87 (BC2000 version)
