ABSTRACT:
A method for removal of at least one contaminant from a liquid is described, wherein a first step in liquid is introduced into a first of a plurality of liquid treatment containers and brought into contact in a liquid-medium suspension with a first quantity of a solid contaminant recovery medium for removing the contaminant for a period of time sufficient to achieve a desired efficiency of recovery of the contaminant. The liquid is then cycled from the first liquid treatment container sequentially through each of the plurality of liquid treatment containers to a final liquid treatment container while contacting the liquid in each of the liquid treatment containers with additional quantities of the medium in liquid-medium suspension for periods of time sufficient to achieve the desired efficiency of recovery in each of the liquid treatment containers. At least a portion of the medium is cycled from the final liquid treatment container through the plurality of liquid treatment containers to the first liquid treatment container in a direction countercurrent to flow of the liquid so as to maintain essentially a constant medium concentration in each of the liquid treatment containers, with the medium being substantially separated from liquid prior to cycling from one container to another container. At least a portion of the medium is transferred from the first liquid treatment container into a medium recycling means, in which the medium is treated with a contaminant recovery liquid for regenerating the medium.
