Full Description

More than 3,000 community water suppliers willhave to treat for arsenic (As) removal as the USEnvironmental Protection Agency's new maximumcontaminant level (MCL) requirements come intoeffect. The authors conducted this study to develop amethod for minimizing the waste produced by As ionexchange during water treatment for As removal. Theyfound that ion exchange with direct brine reuse is a moreefficient and cost-effective process for removing As fromgroundwater than more commonly used processes. Saltconsumption for regeneration is cut by 50%, and spentbrine can be reused 10-15 times or more. This processwill give communities a more cost-effective alternativefor meeting new MCL requirements. Includes 19 references, tables, figures.
