Abstract

A novel bio-physical approach for treating well water contaminated with perchlorate (ClO4¯) at 15 mg/L is reported in this study. In this process, the ClO4¯ was initially treated in an anaerobic fixed-film bioreactor (55 L), followed by a ceramic Micro-Filtration (MF) unit (1.5 μm pore size, 0.12 m2 surface area) and a Reverse Osmosis (RO) unit (0.38 m2 surface area) connected in series. The bioreactor inoculated with a ClO4¯ reducing bacterium Serratia marcescens (Gen bank no. JQ807993) removed ~97% of the ClO4¯ using acetate as substrate (acetate/ClO4¯ ratio = 4). Subsequently, the MF and RO units removed ClO4¯ to
