Application of Vetiver system for treatment and improvement of unconventional water quality

The aims of this study were to evaluate the treatment efficiency and effectiveness of Vetiveria zizaniodesof two samples of unconventional water of Golgohar Mining and Industrial Company. The experimental samples were included mine wastewater and saline ground water. This research was conducted in a greenhouse at Central Water Research Laboratory of University of Tehran. This experiment was designed as Randomised Complete Block Design (RCBD) including two salinity levels with three replications during four weeks. Results showed that treatment efficiencies of Total Dissolved Solids (TDS) and Electrical Conductivity (EC) were equal 31.5 and 28.3 percentages for mine wastewater and 33 and 28 percentage for ground water on fourth week respectively. Also results indicated that among Cations and Anions, SO4 and K parameters have shown highest and lowest rates at the end of fourth week respectively. It concluded vetiver treatment system include valuable potential for unconventional water treatment.
