An experimental study on removal of heavy metals using low cost adsorbents (pilot study)

Abstract

61754 MLD of waste water is generated in India from various sources and about 38791 MLD (62%) of waste water remains untreated and is directly discharged into water bodies which causes severe damage to all the environmental attributes. So this current situation highly demands the need of treating waste water and for this to happen at a faster rate there is a necessity of finding a solution for treating waste water economically using inexpensive methods of treatment. This study deals with the removal of heavy metals such as Chromium, Copper and Zinc from waste water collected from electroplating industry using low cost adsorbents like 'used tea powder' and 'saw dust', these two adsorbents were tested and was known that used tea powder and saw dust has a carbon content of 62.26% and 67.52% respectively and hence has a high probability of removing heavy metals from the waste water.
