  • Chapter 4 Electro-deionization - ScienceDirect

    The chapter discusses the mechanism of the water dissociation reaction in the EDI system. Weakly-ionized species such as silica, carbon dioxide, boron and ammonia are difficult to remove through the membrane process such as reverse osmosis (RO), and electrodialysis reversal (EDR). However, EDI removes these species effectively.

  • Deionization - an overview

    Ultrafiltration (UF) is an excellent way of removing pyrogen contamination from water. Ultrafilters (positively charged nylon 66 membranes) are recommended for the final 'polishing' of water already treated by deionization (DI) or reverse osmosis RO. Ultrafilters remove most organics over 1,000 weight-average molecular weight, such as pyrogens.
