Treatment and Disposal of Regeneration Wastewater from Activated Alumina Columns Used for Fluoride Removal from Groundwater at Rocky Mountain Arsenal.

摘要

The investigation discussed in this report was conducted in support of a concurrent study ongoing at RMA to determine the applicability of activated alumina adsorption for the removal of fluoride from ground water crossing the northern boundary. The applicability study is being conducted by Rubel Hager, Inc. Their assistance and transfer of information is acknowledged. The activated alumina beds must be periodically regenerated when the bed becomes exhausted. This regeneration process results in a caustic wastewater containing a high concentration of fluoride. An environmentally acceptable treatment/disposal process is required for processing of this wastewater during the actual operation of the proposed activated alumina system. The objectives of this study are: (1) To review the existing literature concerning the disposal concentrated fluoride wastewater, and (2) To assess, on a laboratory scale, those treatment processes having the greatest potential for success in treating the regeneration.
