Abstract: Provided herein are methods, systems, and computer-readable media for controlling a deacidification process for an aqueous fluid circulated through a deacidification column. A first pH value, indicative of a pH of the fluid before circulation through the column, is obtained from a first sensor located at an entry of the column. A second pH value, indicative of a pH of the fluid after circulation through the column, is obtained from a second sensor located at an exit of the column. The second pH value is compared to a target pH value for the fluid to determine a pH difference between the second pH value and the target pH value. Based on the first and second pH values, a deacidification capacity of the column is determined. A fluid flow rate of the fluid through the column is adjusted based on the pH difference and the deacidification capacity.

Abstract: A process for removing suspended particles and at least one ionic species from a feed water stream to produce a product water stream, the process includes the steps of forming agglomerates of the suspended particles in the feed water stream; passing the feed water stream containing agglomerated particles through a bed of particulate sorbent material so as to sorb the ionic species from the feed water onto the sorbent to provide a loaded sorbent and filter the agglomerated particles from the feed water using the bed of particulate sorbent material as a filtration medium to load the bed with the agglomerated particles, and thereby produce the product water stream; removing the filtered particles and the ionic species from the filtration medium; and re-using the regenerated sorbent in step b).
