Our current index for adding sodium carbonate to salt water is 0.7-1.0. It used to be 0.2-0.5. Have you ever experienced this?
No, we pre-treat + post-react + film, and the indicator control is 0.3-0.6g/l (excess value). Your excess control value is too high, which may be related to your process, equipment storage capacity, and distance (reaction time). Is your calcium ion very high?
Calcium and magnesium are within 20 ppb, usually 15 or 16 ppb.
What you are talking about is not the index of primary brine, but the index of secondary brine out of the chelating resin tower.
What effect do you think of increasing the amount of sodium carbonate? Does your raw salt have a lot of impurities?
It should not be the amount added. The amount added is adjusted according to the salt quality. The indicator test is the amount remaining after the reaction. The excess sodium carbonate is 0.3~0.6g/l.
The calcium and magnesium of the primary saline is normal, and the analysis sheet says 0 mg/l.

Is excess sodium carbonate, 0.7-1.0
“What does "inadequate response power" mean? Lack of time, fast flow, and limited equipment capabilities? still?
This sodium carbonate excess value is a bit too high. Such a high unit consumption will virtually increase costs. In addition, an excessively high pH value will affect the processing of the following processes.
