Gen2 Exercise

Scenario:

You are working at a municipal water treatment plant that still utilizes a Gen2 chemical feed system. The plant manager has noticed a slight decrease in water quality, specifically an increase in turbidity (cloudiness). You suspect the Gen2 system might be underperforming.

Task:

  1. Identify at least three possible reasons why the Gen2 system might be causing the increase in turbidity.
  2. For each reason, explain a possible corrective action that you could take.

Exercise Correction:

Exercice Correction

**Possible Reasons for Increased Turbidity:**

  1. **Improper Chemical Dosage:** The Gen2 system might not be delivering the correct amount of coagulant or flocculant needed to effectively remove turbidity. This could be due to a malfunctioning feeder, inaccurate calibration, or a change in the raw water characteristics requiring adjustments.
  2. **Clogging or Blockage:** There might be a clog in the chemical feed lines, filter screens, or other parts of the system, preventing the proper flow of chemicals.
  3. **Control System Malfunction:** The Gen2 system's control system might not be functioning correctly, leading to inconsistent chemical dosing or inaccurate feedback. This could be due to a faulty sensor, a programming error, or a problem with the control panel.

**Corrective Actions:**

  1. **Adjust Chemical Dosage:** Check the chemical feed rate settings, the calibration of the feeders, and the flow rate of raw water. Adjust the dosage based on water quality parameters and consult the Gen2 system manual for optimal settings.
  2. **Inspect and Clean System:** Thoroughly inspect the chemical feed lines, filter screens, and other parts of the Gen2 system for any clogs or blockages. Clean or replace components as needed to ensure proper flow.
  3. **Troubleshoot Control System:** Investigate the Gen2 system's control panel, sensors, and programming for any potential issues. Check sensor readings against known water quality values and consult the Gen2 system manual for troubleshooting guidelines. Contact a qualified service technician if necessary.
