Abrégé
(EN)
A method for the treatment of a liquid. The method comprises contacting the liquid within a treatment zone with an adsorbent material, which is then electrochemically regenerated within a regeneration zone following contact with said liquid. A disinfectant precursor species is provided within the regeneration zone and then electrochemically converted to a disinfectant species which can then contact adsorbent material and/or liquid within the regeneration zone, effecting in-situ disinfection and resulting in the presence of residual disinfectant species in the treated liquid. There is further provided apparatus for carrying out such a method.

本发明提供一种处理液体的方法,其包括使液体在处理区内与吸附剂材料接触,在与所述液体接触后将所述吸附剂材料在再生区内进行电化学再生。在再生区中提供消毒剂前体物质,然后将所述消毒剂前体物质电化学转化成消毒剂物质,然后所述消毒剂物质可与吸附剂材料和/或液体在再生区内接触,实施原位消毒,并导致在处理的液体中存在残留消毒剂物质。本发明还提供用于实施所述方法的装置。
