Quality Control in Industrial Cooling Towers
Jul 08 2008
Cooling Towers are used in a wide range of businesses, including heavy
industry, petrochemical companies, refineries, oil and gas companies - as well as large public facilities such as hotels, malls and other shopping centers, etc.
Typically, these towers are designed as closed systems in which circulating water is treated with predetermined concentrations of chlorine,which is used as a disinfectant. The most critical problem
associated with cooling towers is the Legionnella bacteria - a dangerous germ that grows in stagnant water that causes serious diseases, including a fatal form of pneumonia. To prevent the growth of
these bacteria, dependable ongoing monitoring and disinfection of the water is required - and, if Legionnella is detected, immediate drasticmeasures are essential.
Blue Iâs systems offers comprehensive answers to the challenges presented by cooling towers. Their unique set of capabilities enables the precise measurement of chlorine in all types of water even in themost difficult conditions.
The systems provide an accurate, real-time picture of chlorine concentration, allowing the simplified ongoing follow-up of any changes made in chlorine levels, so that decisions can be quickly and efficiently.
It is crucial for chlorine concentrations to bemaintained at exactly the right levels.
If the levels are too low, there is insufficient disinfection of the water, allowing dangerous bacteria to grow.On the other hand, if the levels are too high, corrosion can cause serious damage to the cooling
towers. In this environment, it is difficult for sensors to differentiate between the rust resulting from over-chlorination, and the
chlorine itself - thereby decreasing measurement accuracy. Adding to the
complexity is the fact that treatment processes used in cooling towers often combine chlorine with bromine - a very costly chemical whose use must be carefullymonitored.
Blue Iâs systems measure both chlorine and bromine levels - assuring the thorough ongoing disinfection of water, protecting delicate cooling towers from corrosion, keeping usage of costly bromine to a minimum, and maintaining this complex balance over long periods of time,
succeeding where all other available systems fail.
