Water quality issues in circulating water systems
Thread Content
What impact do parameters such as Cl-, Ca2+, total hardness, turbidity, total phosphorus, total alkalinity, conductivity, concentration ratio, and pH value in the analysis of circulating water quality have on the overall quality of that circulating water? Which factor mainly influences the ease of device design?
The main factor causing scaling in circulating water is the combined effect of water hardness and alkalinity. For other influencing factors, the original poster can consult some information on circulating water treatment.
Additionally, it is necessary to keep the circulating water in motion; stagnant water tends to form scale
Mainly total hardness, turbidity, concentration factor, and pH value
Scaling is mainly related to hardness and pH; temperature may also have some impact. It’s primarily due to calcium and magnesium ions – a lower pH makes scaling less likely. . . .
Total hardness refers mainly to the combined amount of calcium and magnesium, as well as turbidity. The substances that cause scaling are primarily calcium carbonate, magnesium carbonate, calcium sulfate, and similar compounds
The answer on floor 5 is likely the best one, as it is the hardness of the water and its pH value that play the most crucial role in causing scaling in equipment. Scale inhibitors cannot completely prevent scale formation; only softening the water quality can resolve the issue at its root.
The answer above is correct; by using a chemical dosing device to soften the water quality, scaling can be reduced.
I cannot agree with this view. If water is left to stand, it can reach a supersaturated state, in which the product of the concentrations of the scaling components exceeds the solubility product for precipitation, allowing them to exist stably temporarily. However, such a supersaturated solution will immediately precipitate a large amount of sediment upon being disturbed. I was wondering where you got your perspective from.
In addition to traditional methods for preventing scaling, there are now many devices available that can help prevent scaling; it’s worth learning more about them. Where does scaling occur most frequently in your case – in the pipes or in the heat exchangers?
It is mainly the heat exchanger, which needs to be cleaned frequently.
