Comparison of corrosivity between softened water and circulating water
Thread Content
Our company's cooler spray water uses softened water. Can it be changed to circulating water? Which one is more corrosive than softened water or circulating water?
Circulating water often needs to be added with bactericides, algaecides, corrosion inhibitors, etc. However, when the temperature is too high, serious scaling will still occur and requires regular cleaning. Compared with soft water, it is safer, more durable and less corrosive during use. Personal opinion, for reference only.
Circulating water is easy to scale, and at the same time, the water contains many impurities, which can easily block the spray device.
Circulating water can also be used. However, the descaling cycle may be relatively short, and the heat exchanger must be large. Otherwise, the operation may not meet the design conditions due to the presence of a thick layer of scale.
Now that you have used demineralized water, keep using it.
Demineralized water has low turbidity and can be used for spraying without any problem.
If the acid value of the demineralized water is high, the corrosion of the demineralized water will be more severe.
