WHM Exercise:

Scenario:

A water treatment plant is currently using a manual system to add chlorine for disinfection. This system involves manually adjusting the flow of chlorine gas into the water, which is prone to errors and can lead to inconsistent chlorine levels. The plant manager wants to improve the safety and efficiency of the chlorine disinfection process.

Task:

  1. Identify three key WHM concerns with the current manual chlorine disinfection system.
  2. Suggest three USFilter/Zimpro BCH solutions that could be implemented to address these concerns and improve the system's safety and efficiency.
  3. Explain how each suggested solution would improve the system's safety, efficiency, or environmental impact.

Exercice Correction

1. Key WHM Concerns:

  • Safety: Manual chlorine handling is inherently risky due to the potential for leaks, overdosing, and exposure to hazardous gases.
  • Efficiency: Manual adjustments can lead to inconsistent chlorine levels, resulting in less effective disinfection and potential water quality issues.
  • Environmental Impact: Accidental releases of chlorine gas can harm the environment and pose risks to nearby populations.

2. Suggested USFilter/Zimpro BCH Solutions:

  • Automated Liquid Chlorine Feeder: This solution would provide precise and automated dosing of chlorine, eliminating the risk of manual errors and ensuring consistent chlorine levels.
  • Chlorine Vapor Containment System: This system would safely contain chlorine vapors, preventing them from escaping into the atmosphere and protecting workers from exposure.
  • Secondary Containment System: A secondary containment system would catch any accidental leaks or spills, preventing the release of chlorine into the environment.

3. Explanation of Improvements:

  • Automated Liquid Chlorine Feeder: Improves safety by eliminating manual handling, enhances efficiency through consistent dosing, and reduces environmental impact by preventing accidental releases.
  • Chlorine Vapor Containment System: Significantly improves safety by preventing worker exposure to hazardous vapors and minimizes environmental pollution.
  • Secondary Containment System: Provides an additional layer of protection against accidental releases, minimizing environmental impact and ensuring the safety of surrounding areas.
