1. An apparatus comprising:
a cathode compartment comprising a cathode and configured for a continuous flow of a first reaction medium;
an anode compartment comprising an anode and configured for a continuous flow of a second reaction medium;
a central compartment separated from the cathode compartment by a first anion membrane and from the anode compartment by a second anion membrane; and
a brine solution comprising a plurality of anions and cations, wherein the brine solution is located in the central compartment,
wherein the central compartment is configured to continuously receive the brine solution;
wherein the cathode is configured to receive a direct current to conduct an electrolysis reaction of the first reaction medium to produce a first reaction product and/or the anode is configured to receive a direct current to conduct an electrolysis reaction of the second reaction medium to produce a second reaction product;
wherein the first anion membrane is configured to pass at least a portion of the first reaction product from the cathode compartment to the central compartment;
wherein the second anion membrane is configured to pass at least a portion of the anions in the brine solution from the central compartment to the anode compartment; and
wherein the apparatus is configured to form an alkalinized brine solution.
