Dye Effluent: Challenges And Opportunities

Abstract

Treatment of industrial effluents rich in toxic dye, phenolic compounds, heavy metals and toxic level of biological/chemical oxygen demand (BOD/COD) is a challenge for water bodies including aquatic fauna as currently available physio-chemical methods are questionable due to their by-product formation. Microbial based approach coupled with Bio-electrochemical system could be a game changer in this case as heavy metals and organic matters can be removed using this approach and toxic BOD/COD level can also be neutralized along with power output. Novel dye reduction-based electron-transfer activity monitoring (DREAM) assay, if coupled with bio-electrochemical system could be a game changer in this scenario
