Abstract

Develops a highly selective arsenic removal technology that allows small and rural drinking water utilities to comply with the 10 ppb MCL for arsenic. Phase I, proof-of-concept research, was completed in 2005. Subscribers can download this Web-only report. Phase II (#4057) continues to develop the most promising polymeric ligand exchangers (PLEs) developed in Phase I and optimizes brine treatment for safe disposal. Phase II was completed in 2009.
