20-14: Advances in the Monitoring and Control of Cooling Systems ChemistryMonitoring and control of cooling water chemistry has improved considerably over the past few decades. Initially, chemicals were metered into the cooling water in proportion to blowdown water flow. The blowdown flow was either measured directly or, more typically, imputed from a makeup water flow meter. The concentration of water treatment chemical was controlled by manually adjusting the delivery rate of a metering pump by timing the drawdown using a

The benefits of proper control are measurable and translate to improved system efficiency and reliability

Many benefits accrue to all segments of the industry when cooling towers are certified per CTI Standard STD-201

and Chlorine Dioxide are very strong oxidants and as such are actively depleted by things like UV from sunlight

equipment manufacturers have grasped for a concrete method to obtain such a certification
