Abstract

See full text

The methods and systems disclosed here relate to treating water. In certain embodiments, a treatment system comprises an electrochemical water treatment device, a recirculating concentrate stream in fluid communication with the electrochemical water treatment device, a flow control device in fluid communication with a first flow path comprising acidic water and configured to be in fluid communication with the recirculating concentrate stream, and a second flow path comprising feed water and configured to be in fluid communication with the recirculating concentrate stream, and a control system in communication with the flow control device. The treatment system may further comprise a recirculating dilution stream in fluid communication with a second inlet and a second outlet of the electrochemical water treatment device.
