Our sodium hydroxide is 0.2-0.4g/L and sodium carbonate is 0.4-0.6g/L
Sodium hydroxide is 0.1-0.3g/L, sodium carbonate is 0.2-0.6g/L
Sodium hydroxide is 0.1-0.6g/L and sodium carbonate is 0.3-0.6g/L
I personally prefer 0.1-0.3 0.6-0.8g/L
0.1~0.4, 0.4~0.6
Na2CO3 0.6~0.8g/l I can only say that your company is relatively rich. Here I always aim for the lower limit of 0.3 to ensure that the calcium does not exceed the standard. Try to keep it as low as possible, but it is best not to be lower than 0.3. You can compare how much money can be saved in a year between 0.3 and 0.8. It is estimated to be in the millions.
Reply 7# flay0303 You are right, but I don’t know whether the pressure of your resin tower is high or not. What is the quality of the brine entering the tank? If it remains at a high level, do you need to consider increasing the amount of over-alkali? Is the pressure difference of the resin tower high?
Sodium hydroxide 0.1~0.3 Sodium carbonate 0.3~0.5
The total calcium and magnesium content of our secondary brine is less than 20 ppb. Sometimes ICP cannot be measured. The ICP of primary salt water is less than 1ppm. The refined salt used is less calcium and magnesium than the original salt, so the pressure is not high.
