Systems and methods for deacidification of fluids

A system for controlling a deacidification process for an aqueous fluid circulated through a deacidification column containing an ion exchange resin, comprising:

• a flow control in fluid communication with the column and configured for adjusting fluid flow rate of the fluid through the column;
• a first sensor located at an entry to the column, the first sensor configured for obtaining first pH values indicative of a pH of the fluid before circulation through the column;
• a second sensor located at an exit of the column, the second sensor configured for obtaining second pH values indicative of a pH of the fluid after circulation through the column;
• and
• a controller communicatively coupled to the first and second sensor for receiving therefrom the first and second pH values, the controller configured for:
• comparing the second pH values to a target pH value for the fluid to determine a pH difference between the second pH values and the target pH value;
• determining, based on the first and second pH values, a remaining deacidification capacity of the ion exchange resin;
• adjusting, via the flow control, the fluid flow rate of the fluid through the column based on the pH difference and the remaining deacidification capacity.
