摘要： A water purification module includes a fluid path and a control unit. The flow path includes a cationic resin cartridge, an anionic resin cartridge in fluid communication with the cationic resin cartridge, and at least one bypass fluid path arranged to bypass one of the cationic resin cartridge and the anionic resin cartridge, while allowing water to flow to the other of the cationic resin cartridge and the anionic resin cartridge. The flow path also includes a valve arrangement comprising one or more valves configured to selectively direct water to the at least one bypass fluid path. The control unit is configured to control the valve arrangement to direct water to the at least one bypass fluid path based on a production mode of the water purification module.

摘要： Provided are water treatment systems and methods of treating water that include separating boron and concentrating lithium. For example, described are water treatment systems comprising: a first phase comprising a first plurality of electrodialysis units configured to separate boron from a feed stream, and a second phase comprising a second plurality of electrodialysis units, wherein the feed stream of at least one electrodialysis unit of the second plurality of electrodialysis units comprises an outlet brine stream of at least one electrodialysis unit of the first plurality of electrodialysis units, and wherein the second plurality of electrodialysis units are configured to produce a product brine stream achieving 90-99% lithium recovery.
