Abstract: Water is an indispensable part of our lives. The waste water released from industries has the potential to be hazardous to human health. The safe and effective disposal of industrial waste water is thus a challenging task for industrialists and environmentalists. The industrial waste water released as effluent contains heavy metal ions such as cadmium, lead, nickel, chromium etc., which are toxic in nature. In this project, removal of Nickel – an important toxic metal coming from electroplating waste water, using flower waste (whose management is also important) as bio-sorbent was studied and carried out batch wise, continuously , finally fabricating a continuous adsorber that can handle electroplating waste directly. In order to remove color and other impurities Granulated Activated Carbon (GAC) is also incorporated in the adsorber. In batch study, the effectiveness of adsorbents (i) Dried flower waste (ii) Granular activated carbon prepared from flower waste sequentially used in treating metal ion solution was determined. The efficiency of nickel removal was studied in both batch and continuous adsorber and compared.

Keywords: Biosorption, flower waste, Granular activated carbon, metal ion.
