Methods and apparatus for controlling regeneration of an electrode in unidirectional pH adjustment ("UpA") of water. Some embodiments relate to obtaining one or more measured or otherwise known parameters related to a UpA cell (132), and controlling when a regeneration period is started, parameters for the regeneration period, and/or other inputs to the UpA cell based on the parameters. Some embodiments relate to taking the total desired and/or undesired ions production rate and/or energy efficiency of a UpA cell into account in determining discharging parameters for a regeneration period, when the regeneration period should be performed, and/or other inputs to the UpA cell. |
