pH in Drinking Water

pH in Drinking Water

Clean drinking water is essential to human health. Monitoring and controlling pH at multiple stages along the drinking water production process ensures the final product is safe for consumption. Measurement of pH is critical in the drinking water process for the following reasons:

  • Alerting operators to incoming source water problems
  • Allowing efficient use of flocculation chemicals and other treatment regiments 
  • Ensuring that the expected pH of the output water meets consumer expectations
  • Ensuring corrosion control throughout the entire distribution system / infrastructure
