Drinking water treatment by biological process for simultaneous removal of arsenic nitrate and iron in presence of sulphate

Abstract

There are several reports on co occurrence of arsenic nitrate iron and sometimes fluoride in drinking water sources especially in groundwater at wide range of concentrations The main aim of this study was to develop a reactor system using mixed bacterial culture for concurrent removal of arsenic nitrate iron and fluoride from groundwater The flow through attached growth reactor AGR systems developed was successfully tested for its performance in treating synthetically prepared as well as
