Present study summarizes the application of nano-particles as a new green approach for treating highly polluted dark color brown distillery wastewater which has foul odour, high COD and BOD (high organic content). The utilization of lesser amount of different chemicals for the synthesis of nanoparticles is considered a valuable approach in green nanotechnology. Extreme reactivity due to their large surface area of nano-particles has been used to remove toxic compounds of distillery waste efficiently. In the present study, Nanosized zero-valent iron (n-ZVI) have been synthesized and characterized by using principle of Green chemistry. Nanosized zero-valent iron (n-ZVI) and ferrous sulfate heptahydrate have been used to treat the distillery effluent at various concentrations. Comparative study established that treatment was less efficient even with the high concentration of ferrous sulfate heptahydrate whereas was more effective even with the low concentration of n-ZVI. Reaction parameters were also optimized on the basis of concentration of n-ZVI to establish ideal concentration for effective treatment.
