摘要： Systems and methods for treating water are provided. The systems and methods may utilize an electrochemical water treatment device comprising ion exchange membranes. In certain systems and methods, a concentrate stream and a dilution stream may be in fluid communication with ion exchange membranes. The ion exchange membranes may be configured to provide a ratio of a pH of the concentrate stream and a pH of the dilution stream to be less than about 1.0. In some instances, the LSI of the concentrate stream may be less than or about 1.0. In certain instances, the electrochemical water treatment device does not require a reverse polarity cycle.

摘要： 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.
