Removal of Arsenic from Wastewater through Bacteria

Abstract

Arsenic contamination in wastewater is a global dilemma disturbing
millions of the peoples. Arsenic is a toxic metalloid that poses a
significant health risk when consumed in drinking water. One approach
to remove arsenic from wastewater is through the use of bacteria.
Several bacteria species have been identified as potential candidates
for arsenic removal. These bacteria can oxidize or reduce arsenic,
converting it into less toxic forms or sequestering it. This review
summarizes recent studies is on by using bacteria on the elimination of
arsenic from wastewater. The mechanisms of arsenic removal, factors
affecting bacterial activity, and here we discussed wastewater
treatment by the prospective of bacterial systems for large-scale
treatment. The review concludes with a discussion of prospect examine
directions and confronts in the progress of bacterial systems for arsenic
removal from wastewater. Overall, the utilize of bacteria for arsenic
removal shows promise and warrants further investigation as a
potential solution for arsenic contamination in wastewater.
