Comparative Studies for Selection of Technologies for Arsenic Removal from Drinking Water
نویسنده
چکیده
This paper present the possible alternative removal options for the development of safe drinking water supply in the arsenic-affected areas. Each alternative option was studied in the Environmental Engineering Laboratory at Indian Institute of Technology (IIT) Kharagpur, India. In this paper conventional precipitation (Alum and Iron salt) and adsorption (With various types of adsorbent) method were used for arsenic removal. Various parameters such as, coagulant dose, pH, anions concentration and reaction time were studied to establish optimum conditions. Iron salt as a coagulant and Hydrous Granular Ferric Oxide as a fixed bed adsorbent were found to be effective options for arsenic removal.

Background of the Arsenic Crisis The groundwater pollution caused by arsenic (please see Box 1) in a number of Asian countries has led to a major environmental crisis. Some recent estimates indicate that more than 35 million people in West Bengal (India), Nepal and Bangladesh are potentially at risk from drinking arsenic-contaminated water (Smith et al., 2000). The crisis has its roots in anoth...
