Natural materials which are readily available in large amounts in nature may be used as low cost additives. The purpose of this research is to inspect the possibility of the naturally available material; Prosopis Farcta (PF) plant; to improve dyes from textile wastewater. Prosopis Farcta and activated carbon were used as adsorbents in order to make a comparison to remove terasil blue dyes (TB). Batch tests investigated the adsorption isotherm of TB at room temperature and various parameters such as the adsorbent dose, contact time and initial dye concentration. The experimental results showed that the maximum removal efficiency of PF was found to be 85% at a fixed 200 rpm mixing speed, pH value 8, mixing time 90 minutes and the dose of adsorbent 0.5g. The maximum removal efficiency of AC was found to be 96% at a fixed 200 rpm mixing speed, pH value 8, mixing time 90 minutes and the dose of adsorbent 0.5g. The above removal efficiencies were obtained at temperature 24±1 °C and initial TB dye concentration 15 mg/l. Langmuir and Freundlich isotherm models were assigned to analyse the test data. Findings revealed that Langmuir adsorption isotherm was best model for TB adsorption onto AC and PF with energy of adsorption (Qo) 2.495 mg/g and 1.652 mg/g, the maximum adsorption capacity (b) 7.08 l/mg and 0.307 l/mg at coefficient of determination 0.9958 and 0.9718 respectively.
