Treatment of wastewater or effluent using nanotechnology principles has gained more attention recently due to high removal efficacy of toxic pollutants with notable biosafety. In this study, chemogenic and biogenic nano zero valent iron (nZVI) particles were screened for wastewater treatment efficacy of domestic sewage water adapting green science principles. Reduction of iron precursor by sodium borohydride (chemogenic) and tea extract (biogenic) brought about highly stable, nanoscale zero valent iron particles. A notable reduction of wastewater treatment efficacy was recorded in nZVI that synthesizes via biological route, confirmed by drastic reduction in physio-chemical parameters, including biofilm formation. The present study suggests the potential use of biogenic nZVI as a low-cost, eco-friendly agent for wastewater treatment.
