Drafting The Future Of Clean Hydrogen: Build Back Greater With An Additionality Requirement International Council On Clean Transportation
To facilitate ion transfer in low ionic strength solutions, the dilute compartments and at times the concentrate compartments, are filled with ion exchange resins. In an EDI module, a portion of the feed flow, around five% of the volume, continuously washes out the ions from the concentrate compartments. This concentrate outlet, also named the reject stream, is recirculated upstream of the RO system to be recovered, although the dilute compartments deliver purified item water. The electrodeionization approach makes use of ion exchange resins, ion-selective membranes and an applied DC electrical present to take away ions, such as salts, acids and...
