Heavy metal contamination of water has been an issue of great concern since a long time. The water resources have been depleting rapidly and this is not an unknown fact to mankind. Water shortages have become a consistent problem faced by mankind. Every now and then we hear news about contamination of water bodies by industrial effluents or sewage water. Increased agricultural activities, industrial ventures and poor e-waste management are few of the key reasons that are accountable for abnormal rise in the heavy metal concentration in water bodies. Many methods have been devised to purify wastewater but the use of biosorptive materials has gained popularity recently. The techniques like membrane filtration, ion-exchange, carbon adsorption, co-precipitation or adsorption, electrolysis and chemical precipitation are made use of for the elimination of heavy metals from wastewater, but these processes are appropriate for the removal of elevated concentration of heavy metals and are also very expensive. These techniques are not very functional when it comes to the removal of low concentration of metals. This is the drawback that creates scope for using cheap bio sorbents/adsorbents for heavy metal removal from wastewaters. Thus a bio sorption tower for reuse and recycle of agricultural run-off and e-waste was developed using a novel multilayer packed bed. The packed bed was designed by exploring the potential of various inexpensive bio sorbents by using them without any pre-treatment. Lab-scale run of the bio sorption tower thus designed and run with synthetic agricultural waste water showed good potential for bio sorption of heavy metals. [ABSTRACT FROM AUTHOR] |
