Abstract Wastewater from the crystal glass factory can contain arsenic as hexafluoroarsenate. On the basis of a case study, an optimized treatment procedure for a hexafluoroarsenate-containing surface water is presented using a strong basic anion exchanger. To minimize the microbial activity by forming biofilms on the surface of the exchanger material, distinctive technical features were described on the basis of results from laboratory and pilot plant tests. Silver impregnation of the ion exchange material has been shown to be not suitable due to a decrease in capacity by surface covering. Pre-filters appear to be an inexpensive and effective option to increase the lifespan of the filters. A volume of 15 m3 of contaminated water was cleaned up using 1 kg of ion exchange resin on site in 250 hours. The ion exchange process has shown to be capable of cleaning waters contaminated with hexafluoroarsenate.
