Abstract
This study investigated a combined treatment system for groundwater remediation, integrating autotrophic FeS2-based denitrification with electrochemical disinfection. A pyrite-based fluidized bed reactor (P-FBR) achieved consistent nitrate removal efficiency (79%) at ambient temperature, reaching drinking water standards. Electrochlorination using a Pt/Ti anode effectively disinfected the denitrified effluent, eliminating total coliforms. The process is energy-efficient and environmentally friendly, minimizing chemical usage and potentially utilizing renewable energy sources.
