Abstract

Turkey has the richest boron reserve in the world. Colemanite and Tincal, which are some of the ores produced in Turkey, are used in the production of Boric Acid and Sodium Perborates, respectively. As a result of this production process, the amount of solid waste and wastewater is quite high and in order for these wastes to not cause different environmental problems, they must either be disposed in some way or the boron they contain must be removed. In this study, the removal of boron from synthetic waters by nanofiltration was investigated. It was investigated operational parameters such as boron feed concentration, pH, pressure and flow rate at boron removal experiments. DMSO was used as complex agent and it was thought that DMSO forms a complex with water. Boron removal was not obtained at experiments, which was not used DMSO. The separation of the solid boron compound was studied in a wide range of conditions by nanofiltration (NF). The best result with DMSO was 290 ppm effluent boron concentration for 3000 ppm influent boron concentration with efficiency of 92%. In the final stage, cross-flow membrane filtration was used for the separation of solid-liquid. The result of this study showed that the boron recovery efficiency was as high as 95% from the wastewater.
