Exercise:

Scenario: You work at a wastewater treatment plant and need to monitor the pH of the effluent before it is discharged into a river. You are using a Hach One pH electrode and a compatible meter. The effluent pH should be between 6.5 and 8.5.

Task: The meter currently reads a pH of 5.8. Based on this reading, what actions should you take?

Exercice Correction

The effluent pH is below the acceptable range (6.5-8.5). Here are the steps to take:

  • **Investigate the cause:** Determine why the effluent pH is too low. This could be due to a malfunctioning pH control system, changes in the influent wastewater, or an error in the measurement.
  • **Adjust the treatment process:** Based on the identified cause, adjust the treatment process to increase the pH to the acceptable range. This might involve adding chemicals, adjusting the flow rate, or correcting any operational errors.
  • **Continue monitoring:** Regularly check the effluent pH using the Hach One pH electrode and meter. Document all readings and actions taken.
  • **Report and document:** Report the issue and the corrective actions taken to your supervisor and maintain detailed records for future reference.
