Özet

In this study, an investigation study was undertaken to reduce the value of boron in Eti Mine Works General Directorate, Bandirma Boron and Acid Factory, in Turkey, wastewater under discharge limit by using Calcium hydroxide Ca(OH)(2) via Response Surface Methodology (RSM) and initial pH, reaction time, reaction temperature, and the ratio of Ca(OH)(2)/B2O3% were selected as experimental parameters. RSM proposed quadratic model for central composite design (CCD). The proposed quadratic model fit well to the experimental data that it could be used to navigate the design space according to ANOVA results. The obtained data showed that under laboratory conditions, the value of boron in wastewater was reduced succesfully under the discharge limit (Boron<500 mg/L) from average 7006 mg/L to 487 mg/L.
