Abstract: A low energy water treatment system and method is provided. The system has at least one electrodialysis device that produces partially treated water and a brine byproduct, a softener, and at least one electrodeionization device. The partially treated water stream can be softened by the softener to reduce the likelihood of scale formation and to reduce energy consumption in the electrodeionization device, which produces water having target properties. At least a portion of the energy used by the electrodeionization device can be generated by concentration differences between the brine and seawater streams introduced into compartments thereof. The brine stream can also be used to regenerate the softener.

Abstract translation: 提供了一种低能水处理系统和方法。 该系统具有至少一个电渗析装置，其产生部分处理的水和盐水副产物，软化剂和至少一个电去离子装置。 部分处理的水流可以由软化剂软化，以减少形成水垢的可能性并降低产生具有目标性能的水的电去离子装置中的能量消耗。 电去离子装置使用的能量的至少一部分能够通过引入其隔室中的盐水和海水之间的浓度差产生。 盐水也可用于再生软化剂。

Abstract: Methods of operating an electrochemical separation device is disclosed. The methods include operating the electrochemical separation device in an active mode until the resistance reaches a predetermined threshold, regenerating the electrochemical separation device in a passive mode until the resistance reaches a predetermined threshold, and resuming operation of the electrochemical separation device in the active mode. The methods also include operating the electrochemical separation device in an active mode for a predetermined period of time, regenerating the electrochemical separation device in a passive mode for a predetermined period of time, and resuming operation of the electrochemical separation device in the active mode. Water treatment systems include the electrochemical separation device and a control module are also disclosed. Methods of facilitating operation of the electrochemical separation device by providing a control sequence are also disclosed.
