Troubleshooting Common Issues with Sodium Hypochlorite Generators
On-site sodium hypochlorite generators (OSHG) offer numerous advantages for various applications, providing a safer and more efficient way to produce disinfectant. However, like any piece of equipment, OSHG systems can experience occasional issues. This blog post outlines common problems encountered with sodium hypochlorite generators and provides troubleshooting tips to help you keep your system running smoothly.
Common Issues and Troubleshooting Steps:
-
Low or No Sodium Hypochlorite Production:
-
Possible Causes:
- Low Salt Concentration: Check the brine tank and ensure the salt concentration is within the manufacturer's recommended range. Add salt as needed.
- Low Water Flow: Verify that the water supply to the generator is adequate and that there are no blockages in the lines or filters.
- Power Supply Issues: Check the power supply to the generator and ensure it is receiving the correct voltage.
- Electrode Fouling or Scaling: Inspect the electrolytic cells for scaling or fouling. Clean the cells according to the manufacturer's instructions.
- Cell Failure: If cleaning doesn't resolve the issue, the electrolytic cells may need to be replaced.
- Control System Malfunction: Check the control panel for any error messages or malfunctions. Consult the manufacturer's manual for troubleshooting steps.
-
Troubleshooting Steps:
- Check salt and water levels.
- Verify power supply.
- Inspect and clean electrolytic cells.
- Check control system.
- Consult the manufacturer's manual or contact technical support.
-
High Salt Consumption:
-
Possible Causes:
- Leaks in the System: Check for leaks in the brine tank, piping, and electrolytic cells.
- Inefficient Electrolysis: Scaling or fouling of the electrodes can reduce the efficiency of the electrolysis process, leading to higher salt consumption.
- Improper System Settings: Verify that the system is operating at the correct settings for salt concentration and production rate.
-
Troubleshooting Steps:
- Inspect the system for leaks.
- Clean the electrolytic cells.
- Check system settings.
-
High or Low pH of Generated Solution:
-
Possible Causes:
- Improper Salt Concentration: Incorrect salt concentration can affect the pH of the generated solution.
- Water Quality Issues: The pH and alkalinity of the incoming water can also influence the pH of the generated solution.
- Electrode Issues: Worn or damaged electrodes can affect the pH.
-
Troubleshooting Steps:
- Check and adjust salt concentration.
- Analyze the incoming water quality.
- Inspect the electrodes.
-
Scaling or Fouling of Electrolytic Cells:
-
Possible Causes:
- Hard Water: High mineral content in the water can lead to scaling.
- Impurities in Salt: Impurities in the salt can contribute to fouling.
- Insufficient Cleaning: Inadequate or infrequent cleaning can allow scale and fouling to build up.
-
Troubleshooting Steps:
- Use softened water if necessary.
- Use high-purity salt.
- Implement a regular cleaning schedule according to the manufacturer's instructions.

Preventative Maintenance for Optimal Performance:
Preventative maintenance is crucial for minimizing problems and maximizing the lifespan of your OSHG system. Key preventative maintenance tasks include:
- Regular Cleaning of Electrolytic Cells: Follow the manufacturer's recommended cleaning schedule.
- Regular Inspection of System Components: Check for leaks, corrosion, and wear and tear.
- Monitoring of Operating Parameters: Regularly monitor key parameters such as current, voltage, temperature, and sodium hypochlorite concentration.
- Calibration of Sensors and Controls: Ensure that sensors and control systems are calibrated regularly for accurate readings and control.
- Use of High-Quality Salt and Water: Use salt and water that meet the manufacturer's specifications.
When to Contact a Professional:
If you are unable to resolve an issue using the troubleshooting steps outlined above, or if you are uncomfortable performing any maintenance tasks yourself, it is important to contact a qualified technician or the OSHG system manufacturer for assistance.
By understanding common issues and implementing proper maintenance practices, you can maximize the efficiency and lifespan of your sodium hypochlorite generator, ensuring consistent and reliable disinfection for your specific application.
If you have any questions or require assistance with your sodium hypochlorite generator, please contact us or consult your system's manual. Regular maintenance and prompt troubleshooting are key to keeping your system operating at peak performance.
