Method for the treatment of liquids using regeneratable adsorbent material

摘要

A method for the treatment of a liquid comprises contacting the liquid within a treatment zone with an adsorbent material, which is then electrochemically regenerated within regeneration zone following contact with the liquid. A disinfectant precursor species is provided within the regeneration zone and then electrochemically converted to 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. The adsorbent material may be activated carbon and the disinfectant precursor may be sodium chloride, hypochlorite or hypochlorous acid.
