Calcification is one of the most common damages to surfaces subject to heat exchange. Scale is recognized here by its mineral origin, usually composed of calcium or hardening salts (calcium carbonate). In order to control calcification, which can be observed on coolers where the temperature fluctuates, methods that can be said to be easy can be tried.
Cooling tower scaling is caused by three main factors. These can be listed as follows:
- INADEQUATE USE OF CHEMICALS
Chemical scale inhibitors are used in places that are prone to calcification, such as the cooling tower of water treatment systems. There are many different types of scale inhibitors, all of which are actually prepared to be used in variable situations by showing different functions.
One of the best examples of this is a system that uses a calcium carbonate inhibitor, but if there is a high silicate sensitivity, it is certain that there will be problems with silicate in the future.
2. REDUCTION OF THE CHEMICAL IN THE SYSTEM
Choosing the ideal chemical for the system and determining which products will perform best with it is one of the most important factors for the long-term operation of water treatment systems. For example, some scale inhibitors may decrease as they are used or with excessive use of oxidizing biocides. If the scale inhibitor decreases, there will be a predictable increase in scale and the performance of the chiller will be reduced.
