This guide introduces the basic working of the SUNRUI ballast water treatment system. By explaining the process, key parts, and system checks, you’ll gain a clear understanding of how to operate the system effectively. We’ll also go over the three main operating modes that are controlled through the HMI (Human-Machine Interface). These modes are Ballast Mode, Deballast Mode, and Tank Cleaning Mode. Below, we explain each mode step by step.
1. Ballast Mode
Steps to Start:
- Select Pump Mode: On the bottom right of the HMI ballast screen, choose the seawater pump mode. Normally, Pump Unit 1 matches Electrolysis Unit 1, and Pump Unit 2 matches Electrolysis Unit 2. If you are in freshwater, switch them around.
- Choose Ballast Mode: Tap the ballast mode button. Pair Electrolysis Unit 1 with Pumps 1 & 2 and Filter 1, and Unit 2 with Pumps 3 & 4 and Filter 2. You can also reverse these choices.
- Manual Valve Check: After switching modes, ensure the manual valves for the seawater pump and dosing pump are in the correct position.
Starting the System:
- Select the right operating mode—choose “Ballast EDU/01” on the screen.
- Give HMI control permission, then confirm that the valve positions on the screen are ready for operation.
- If all the conditions are ready, click the START button.
- The fan in the electrolysis unit will start.
- The filter outlet valve will open.
- The screen will show “waiting for ballast pump signal.”
- Once the filter valve opens, the ballast pump will start, and the seawater pump, dosing pump, and electrolysis unit will begin running automatically.
- After everything stabilizes (no alarms), the system will switch to auto mode.
Managing Operating Parameters:
- Click the EDU Parameters to check sensor data like power, temperature, pressure, valve positions, and TRO values.
- Click AFU Parameters to check filter wash times and pressures.
- Click the Rectifier section to see voltage, current, and temperature details.
- Use Data Logging to view operation history and system performance data.
Stopping the System:
- After ballast operations are complete, click STOP.
- The ballast pump will stop automatically, along with all other pumps.
- The fan will stop after running for 10 minutes.
2. Deballast Mode
Steps to Prepare:
- Check Valves: Make sure electrolysis unit and filter valves are closed, but open the neutralizing unit valves.
- Sampling and Dosing: Open the right sampling valves, check the TRO and neutralizing chemicals, and prepare them as needed.
Starting the System:
- Select “Deballast Mode” on the screen.
- In the mode options, pair Pump 1 with Filter 1 and TRO Unit 1.
- After giving HMI permission, click START. The dosing pump and ballast pump will start automatically.
- Monitor the chlorine levels closely within the first 10 minutes to ensure safe discharge.
Stopping the System:
- Click STOP when done.
- The pumps and dosing will stop automatically.
- Close related valves and air supply lines after stopping.
3. Tank Cleaning Mode
Steps to Start:
- Check Valves: Confirm that the correct cleaning valves are open.
- Select “Tank Cleaning Mode” on the screen.
- If all conditions are met, click START.
During Operation:
- Watch the chlorine monitoring system to ensure everything is working correctly.
- If no alarms occur, the system will continue cleaning without interruption.
Stopping the System:
- After cleaning, first close the tank cleaning valves.
- Stop the ballast water treatment system by following the same steps as before.
4. Shutting Down the System
- In the HMI, click the power button to turn off the system.
- The system will ask for confirmation—click OK.
- Once the main system is shut down, you can also power down the backup system in the same way.
