1.1 Introduction
Selenium contamination is worldwide phenomenon. Contamination of selenium in surface and ground water in river basins is one of the critical problems nowadays.
As selenium shows a narrow tolerance limit (40–400 mg/day), the problem of both deficiency and toxicity of Se have being identified in many parts of India and the world (WHO 2009). Different countries are making efforts to remove selenium from water using different technologies. Some specific processing technologies include reduction, bioremediation, phytoremediation coagulation, electro‐coagulation, co‐precipitation, electric kinetics, adsorption, chemical precipitation, and membrane technology.
