Industrial Emissions

The rapid industrialization during last few decades without any concern for its impact on the environment has put the survival of living beings at stake. Organic and inorganic compounds either deliberate through industrial emissions or accidental through chemical or oil spills etc. released into the environment. The heavy metals such as Pb, Cr, Cd, Ag, As, Cu, Ni, V, Co Hg, Se and Zn are introduced into water streams from various industries viz. refining of ores, incinerators, electroplating, paints, mining, alloys, batteries, pesticides, paper industry, leather tanning, sludge disposal, organo-chemicals, petrochemicals, fertilizer industries, automobiles, metal processing etc. Biosorption using low cost biosorbents has been found considerably effective for removal and recovery of heavy metals from aqueous streams. Present studies involve the investigation of biosorption potential of selected biomaterials (selected on the basis of cost, abundance in availability and physic-chemical properties) for sequestering heavy metals Cd(II), Cu(II), Pb(II) and Cr(VI) from simulated aqueous solutions and analyse the adsorption kinetics for this heavy metal removal.

Universal Application

In recent years, there has been increasing interest in developing green biocomposite for industrial wastewater treatment. In this study, prawn-shell-derived chitosan (CHT) and kaolinite rich modified clay (MC) were used to fabricate biocomposite beads with different compositions. Prepared composite beads were characterized by FTIR, and XRD, and SEM. The possible application of the beads was evaluated primarily by measuring the adsorption efficiency in standard models of lead (II) and methylene blue (MB) dye solution, and the results show a promising removal efficiency. In addition, the composites were used to remove Cr (VI), Pb (II), and MB from real industrial effluents. From tannery effluent, 50.90% of chromium and 39.50% of lead ions were removed by composites rich in chitosan and 31.50% of MB was removed from textile effluent by a composite rich in clay. Moreover, the composite beads were found to be activated in both acidic and basic media depending on their composition, which gives a scope to their universal application in dye and heavy metal removal from wastewater from various industries.
