Abstract
Apparatus and method for the treatment of a contaminated liquid to remove contaminants from said liquid. The apparatus comprises a bed of a carbon based adsorbent material capable of electrochemical regeneration, at least one pair of electrodes operable to pass an electric current through said bed to regenerate the adsorbent material, and means to admit contaminated liquid into said bed to contact said adsorbent material at a flow rate which is sufficiently high to pass the liquid through the bed but below the flow rate required to fluidise the bed of adsorbent material.

A method for removing contaminants from a contaminated liquid, the method comprising admitting contaminated liquid into a bed of a carbon based adsorbent material capable of electrochemical regeneration at a flow rate which is sufficiently high to pass the liquid through the bed but below the flow rate required to fluidise the adsorbent material within the bed;
- and passing an electric current through the bed to regenerate adsorbent material that has adsorbed contaminants from the contaminated liquid.
