Description:
An innovative ion exchange system for the removal and potential recovery of valuable heavy metals from industrial process and waste streams is proposed which eliminates or reduces the need for chemical regenerants and utilizes unique inherently non-polluting driving forces. The process encompasses a specific natural zeolite with specific crystalline geometry to provide size exclusion ion exchange. Secondary pollutants and waste shifting from one environmental media to another are largely avoided with the process.Supplemental Keywords:
