When the pH of the brine fed into the tank is not within the specified range, how is it adjusted through the step involving the primary brine? The pH of the 150 saltwater storage tank keeps dropping and remains around 8! ! ! ! How to adjust? ? ?
What is the pH value of the brine after the Kay membrane filter? What is the pH value of the brine in channel 3#? Should more salt or acid be added? To increase the pH value of the saline solution, it is necessary to start by adding NaOH in the pre-reaction tank at the source
This likely requires a systematic analysis of the entire brine process; from what you say, it’s not just a problem with a single step
Hydrogenation, sodium oxide, sodium carbonate! The indicator can only go up! In this way, the pH value might go up!
This requires a comprehensive consideration of the system processes; it is not possible to simply increase the amounts of sodium hydroxide and sodium carbonate. Excessive alkali content can also have adverse effects, especially in the presence of impurity ions.
Add a little less salt after the brine, and the acidity will increase
After the brine has been filtered, add salt; use a small amount of acid, so that the salt and acid can be diluted to a level that is easy to adjust in your setup. Is the pH value okay for the salt treatment you carried out earlier? ?
