| Abstract |
The report describes work on the removal of hexavalent chromium from plating rinse waters employing various treatment processes. Information was sought by questionnaire and by waste water analyses on the type of waste produced by smaller electroplating plants. Laboratory studies were conducted on several nonconventional methods for treatment of these wastewaters including ion flotation, adsorption on activated carbon, and solvent extraction. A demonstration pilot-plant study also was conducted on the activated carbon process employing actual rinse waters from a hard chrome plating operation. The results of the various phases of the study indicated that activated carbon adsorption for chromium removal may have practical application in many small plating plants. |
