Why is it essential to monitor temperature in a water treatment facility?

Monitoring temperature in a water treatment facility is crucial for managing chemical reactions and ensuring proper contact time. Temperature directly affects the rate of chemical reactions, including disinfection processes, coagulation, and flocculation. For instance, higher temperatures can accelerate the rate of disinfection by chlorine or other chemicals, leading to more effective pathogen removal. Conversely, if the temperature is too low, these processes may be less effective, which could increase the required contact time for chemicals to perform adequately.

In addition, temperature influences the solubility of certain chemicals and the density of water, which can impact overall treatment efficiency. Adjusting the dosage of chemicals based on temperature can be necessary to maintain water quality. By closely monitoring temperature, operators can make timely adjustments to chemical feeds and operational practices to optimize water treatment processes and ensure compliance with health and safety standards.
