Aluminum electrocoagulation: defluoridation technology for Andhra Pradesh, India

摘要

This paper begins with an overview of the origin, magnitude, geographical distribution, and healthconsequences of the geogenic fluoride contamination problem around the world and particularly inNalgonda District, Andhra Pradesh, India. Various current defluoridation technologies are discussedand electrolytic defluoridation (EDF), developed by the Indian National Environmental EngineeringResearch Institute, is proposed as a potential sustainable solution for groundwater treatment in SouthIndia. The paper concludes with a discussion of future research plans to test if EDF meets therequirements to make it an effective solution for Nalgonda: it is culturally acceptable, technically feasibleand robust in a rural setting, and operation and maintenance require minimal capital expenditure andskilled labor.
