Demonstration of Regenerable, Large-Scale Ion Exchange System Using WBA Resin in Rialto, CA
Abstract
The objective of this demonstration was to test and validate weak base ion exchange (WBA IX) technology using established performance objectives in order to obtain permitting and certification from the California Department of Public Health (CDPH) as an approved perchlorate treatment technology. WBA IX is a process developed by ARA and Purolite and is comprised of three unit operations: pretreatment (pH and alkalinity reduction), ion exchange with two packed-bed vessels configured in series (multi-barrier perchlorate removal), and post treatment (restoration of pH and alkalinity). This specific 1,000 gallon per minute system was constructed by Applied Research Associates, Inc. (ARA) to treat groundwater at the Rialto No. 3 well site in the Rialto-Colton, CA area under Environmental Strategic Technology Certification Program (ESTCP) Project No. ER-0312, Perchlorate Removal, Destruction, and Field Monitoring Demonstration.
