True or False? Cooling tower sump water should always be tested at the same temperature.

The correct answer is that cooling tower sump water should always be tested at the same temperature because consistent temperature readings ensure accuracy and reliability in water quality assessments. Variability in temperature can alter the solubility of gases and minerals in the water, potentially leading to misleading test results. For example, colder water may hold more dissolved oxygen compared to warmer water, impacting corrosion and biological growth assessments. Testing at a consistent temperature allows for effective monitoring of trends and more efficient management of water treatment processes. Maintaining standard testing conditions is critical for making informed decisions regarding maintenance, chemical treatment, and overall system health in a cooling tower application.
