  • Removal of contaminants and recovery of metals from waste solutions
    Patent number: 5173179
    Abstract: Apparatus for removal of a desired material from a liquid is described, in which the liquid is cycled through a plurality of liquid treatment containers in a first direction and brought into countercurrent contact with a medium for recovery of the desired material cycled through the treatment containers in a second, opposite direction. After treatment of the liquid, the medium is advantageously regenerated in a plurality of medium regeneration containers. The used medium is cycled through a plurality of medium regeneration containers in a first direction and brought into countercurrent contact with a medium regeneration liquid cycled through the regeneration containers in a second, opposite direction.

  • Removal of contaminants and recovery of metals from waste solutions
    Patent number: 5066371
    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.
