(EN) Adsorption of contaminants from liquid and electrochemical regeneration of adsorbent
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.
