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.
