CaRBoKem: A Biofilter to Treat Heavy Metals by using the Household Waste Products

Abstract

Environmental toxic waste from heavy metals along with minerals within the waste matter is one of the most significant issue in an Asian country. The activities like industrial operations particularly mining, agricultural processes and disposal of industry waste materials; their concentration has redoubled to hazardous levels. Major metals in industrial sewage represent Cu, Cr3+and Pb etc. So far, varieties of inexpensive strategies are reviewed for the removal of these metals. The various processes include chemical precipitation, reverse diffusion, electro qualitative analysis, nanofiltration and floatation. But these strategies have many disadvantages like high chemical agent demand, unpredictable metal particle elimination, and production of unhealthful sludge. Surface absorption method being terribly straightforward, economical, effective and versatile has become the most popular strategies for removal of unhealthful contaminants from waste matter. This paper gives a new idea for the utilization of natural materials as adsorbents for significant metal removal from industrial waste water. The components used are mustard plant roots, human hair and some common house hold waste products such as, egg shell and coconut shell. Utilizing their adsorbent properties in an efficient way, it can be used to filter industrial heavy metals which cause pollution.
