The water treated with ion exchange resin has a higher hardness than ordinary cooling water
Thread Content
It was the first time that water hardness was tested recently, but during the measurement it was found that the hardness of water that has been treated with ion exchange resin is higher than that of the water in the cooling circulation tank What’s going on here (no substances have been added to the water in the cooling tank)?
If it is an anion exchange resin that has been used, such data results are possible since it does not have the function of removing cations. In addition, water treatment agents are added to the circulating water; if the water sample is not properly treated when measuring hardness, the measurement results may also be low.
It is necessary to determine whether the softening bed has failed; if it has failed, calcium and magnesium ions accumulate within the bed layer, and the hardness of the water that leaks out will be higher than that in the tank.
