Abstract
Contaminants are removed from a quantity of contaminated liq. in a treatment reservoir (2,28) contg. a carbon based adsorbent material capable of electrochem. regeneration. The adsorbent material is in the form of a bed supported on a plate (6) at the base of the reservoir. The bed is agitated for a period to distribute the adsorbent material in the liq. and adsorb contaminant therefrom. At the end of the period the agitation ceases, and the bed of adsorbent material is allowed to settle. The adsorbent is then regenerated, during or after settlement, by passing an elec. current through the bed to release from the adsorbent gaseous products derived from the contaminant, in bubbles rising through the decontaminated liq. in the reservoir. Various methods of regenerating the adsorbent material are disclosed, as are app. in which the method can be applied. [on SciFinder(R)]
