Cooling & Boiler Water Treatment
Cooling Water Treatment Problems:
Cooling systems—especially those using cooling towers—face several recurring issues:
– Scaling
Caused by dissolved minerals (like calcium and magnesium) precipitating out and forming deposits on heat exchange surfaces. This reduces heat transfer efficiency and increases energy costs.
– Corrosion
Occurs when untreated or poorly treated water reacts with metal surfaces. This can lead to leaks, equipment failure, and costly repairs.
– Fouling
Dirt, dust, debris, and corrosion by products can clog systems and reduce flow rates, leading to overheating and inefficiency.
– Biological Growth (Biofouling)
Warm water and nutrients create a perfect breeding ground for bacteria and algae. This not only affects performance but can also pose health risks.
Boiler Water Treatment Problems
Boiler systems are even more sensitive due to high pressure and temperature:
– Corrosion
Often caused by oxygen, carbon dioxide, or acidic conditions in the feedwater. It can lead to thinning of boiler tubes and catastrophic failure.
– Scaling/Deposition
Minerals like calcium carbonate form hard deposits that insulate heat transfer surfaces, reducing steam production and increasing fuel usage.
– Carryover
When water impurities are carried into the steam, they can damage downstream equipment like turbines and condensers.
