Three new technologies, advanced ion-exchange operations with indefinite brine recycling
(AIXO-IBR), microsand assisted oxidation adsorption (MAOA), and coagulation-assisted
ceramic filtration (CCF), were pilot tested for arsenic removal capabilities in Scottsdale,
Arizona; Tucson, Arizona; and Billings, Montana. Preliminary design parameters and cost
curves were developed based on the results of the year-long testing. In general, the capital cost
of these three technologies ranges from $500,000 to $1,200,000 for a one million gallon per day
(mgd) facility, excluding building and land costs, with annual operations and maintenance
(O&M) costs being $75,000 to $200,000. Capital and O&M costs were proportional to system
complexity, with the MAOA and CCF processes being more economical than an AIXO-IBR
system. Possible additional savings realized by co-removal of other contaminants were not
considered in this study. Includes 6 references, tables, figures.
