What causes high saltwater hardness?
By high hardness, you probably mean a high content of calcium and magnesium ions. There are two possible sources for this issue: either the original salt contains a high level of calcium and magnesium ions, or the water used in the salt processing process has high hardness. Additionally, test the recycled water again; it’s possible that the level of calcium and magnesium ions in it is high, but not necessarily.
The hardness of the sodium sulfite solution, as determined by laboratory analysis yesterday, was 7.6; pure water basically has no such issue! (We use pure water to prepare sodium sulfite.) However, the hardness of the distilled water is 1.7. Is there any relationship between hardness and sodium sulfite?
Convert it to g/L; let me see what the value is. Why do you use hardness as the unit?
There’s nothing to do! I really can’t find the reason! We can only start with the refined product!
Here are some personal suggestions for your reference: 1. Raw salt – Has a similar situation occurred before? If the quality of the raw salt remains unchanged, please pay attention to whether any changes occur from when the raw salt arrives until it is used. 2. Pipes: Have the pipes in the brine purification system been replaced? Is the replacement pipe made of low-calcium-magnesium rubber? 3. Process: Source of chemical saline ； Whether there was a failure in the chelating resin process, etc
Salt, chelating resin, water, piping.
