Exercise: Micro/2000 Application

Scenario: A water treatment plant is using the Micro/2000 to monitor the residual chlorine levels in the distribution system. The plant's target chlorine level is 0.5 ppm. The Micro/2000 readings show the following:

  • Location 1: 0.4 ppm
  • Location 2: 0.6 ppm
  • Location 3: 0.3 ppm

Task:

  • Identify the locations that are out of compliance with the target chlorine level.
  • Explain what actions the plant operator should take to address the non-compliant locations.

Exercice Correction

* **Locations out of compliance:** Location 1 (0.4 ppm) and Location 3 (0.3 ppm) are below the target chlorine level of 0.5 ppm. * **Actions to take:** * **Location 1:** The operator should slightly increase the chlorine feed rate to raise the chlorine level at this location. * **Location 3:** The operator should investigate the reason for the low chlorine level. This could be due to a leak in the pipe, excessive demand from consumers in that area, or a problem with the chlorine feed system. Once the cause is identified, the operator should take corrective action to restore the desired chlorine level.
