Claim:
1. A method comprising: flowing a process solution into a BPMED system with a BPMED apparatus having at least two compartments separated by membranes, wherein the process solution is one of a seawater solution, a brine or water that has absorbed gaseous CO flowing an electrode rinse solution into the BPMED apparatus only across electrodes in the BPMED apparatus; applying a voltage to the BPMED apparatus and the process solution is acidified and basified, and dissolved CO flowing the acidified and basified process solution out of the BPMED apparatus; desorbing the CO combining the acidified and basified process solution such that the process solution is approximately neutral pH; and discharging the process solution from the BPMED system.
