Physico-chemical analysis of selected industrial effluents and its treatment using novel biocarbon

Abstract

In the present research work, Industrial effluents from a sugar industry, thermal power plant and a leather industry wastewater are collected in selected locations in Chennai region during January 2018 to December 2019. In the present research work, the following essential physico-chemical parameters such as colour, pH, electrical conductivity, TDS, TSS, TH, DO, BOD, COD and metals such as calcium and magnesium, anions of chloride, sulphate and nitrate was determined. In addition, selected heavy metals for instance Cu, Cd, Pb, Ni and Cr which are commonly found in the industrial wastewater is quantified for assessing the level of pollution load in the wastewater. In the present research work, the removal of heavy metal pollutants and the organic load was carried out using AIBC as adsorbent and the results indicates that, in sugar, thermal power plant and leather industry wastewater, the percent removal of Cu is 91.23, 90.32 and 81.12 and Cd is 92.34, 94.64 and 92.20, Pb is 93.64, 95.15 and 90.74, Ni is 90.59, 94.79 and 82.31 and Cr is 93.85, 92.38 and 84.95 respectively. In the present investigation, the use of biocarbon produced from the leaves of Lawsonia inermis and interfaced with alumina as support material was used as an effective, low-cost and inexpensive material for the removal of heavy metals Cu, Cd, Pb, Ni and Cr from selected industrial effluent for the treatment of wastewater.
