After the circulation water concentration ratio is tightly controlled, if the hardness exceeds the specified limit, does this indicate an increase in the level of metal ions in the water, thereby posing a corrosion risk?
It’s necessary; calcium ion levels will increase significantly
If the metal ion is calcium, there should be a risk of scaling, right? If iron ion levels are high, corrosion may occur. Is that so? :)
When the concentration factor is increased, not only does the content of metal ions rise, but the anions in water also increase. Generally, increasing the concentration ratio increases the risk of scaling. Whether it is scaling or corrosion depends on the water pH and calcium and magnesium ions
If the appropriate chemicals are used, there is no risk at all, and it is also possible to keep the system operating without discharge for an extended period of time. That’s how we operate.
How to deal with sludge that has not been discharged for a long time?
After the concentration factor is tightly controlled, in theory, the concentration of all ions increases. It is possible to calculate the concentration factor for each individual ion; by comparing these values with the normal concentration factors, it can be determined whether there is any loss or increase in the ions, and thus whether scaling or corrosion exists in the system.
It cannot be simply assumed that corrosion and scaling in water are two opposing processes; however, their occurrence can be controlled with the use of chemicals. It is also necessary to control the problems of sludge formation and corrosion caused by microorganisms
The same is true for our company: as the concentration ratio increases, the level of metal ions also rises to some extent. If cost considerations are not taken into account, it is necessary to modify the formula of the chemical agents, but care must be taken regarding equipment corrosion and scaling.
Determining whether there is scaling or corrosion in circulating water is not a simple matter; classic indicators such as L.S.I., R.S.I., and P.S.I. do not indicate the presence of any problem. Therefore, discussing only the salt content (hardness, alkalinity, salinity) has only a guiding role regarding scaling and corrosion, and it does not provide actual insights. What is important is to consider the operating conditions of the system, such as the presence of bacteria and algae as well as temperature. It is best to use monitoring equipment, such as heat exchanger monitors or test plates, to assess the actual situation.
Blind guy, why the hell don’t you reply to my post?
