Claim 16:
17. The OAE system of claim 16,
wherein the plurality of valves comprises:
a first three-way valve connected to the salt inflow line between the salt buffer tank and the at least one salt chamber and operably coupled to the acid inflow line by the first cross-feed line, and
a second three-way valve connected to the base inflow line between the base buffer tank and the at least one base chamber and operably coupled to the acid inflow line by the second cross-feed line; and

wherein the control circuit is further configured to control the first three-way valve and the second three-way valve such that:
during said each base-generating operation, the feedstock solution flows from the salt buffer tank through the first three-way valve to the at least one salt chamber and the base solution flows from the base buffer tank through the second three-way valve to the at least one base chamber, and
during said each descaling maintenance operation, at least a portion of the acid solution flows from the acid buffer tank through the first and second three-way valves to both the at least one salt chamber and the base chamber.
