Abstract: Pollution of water by organic and inorganic chemicals is of serious environmental concern. Non biodegradable materials like heavy metals, refractory organics are not removed during the conventional treatment process. In order to meet the regulatory standards and for safe disposal, it is necessary to go for secondary treatment Adsorption as a wastewater treatment process has aroused considerable interest during recent years. Commercially activated carbon is regarded as the most effective material for controlling the organic load. However due to its high cost and about 10-15 % loss during regeneration, unconventional adsorbents like bagasse fly ash, peat, lignite, bagasse pith, wood, saw dust etc. have attracted the attention of several investigations and adsorption characteristics have been widely investigated for the removal of refractory materials for varying degree of success. The aim of the work is to explore the possibility of utilizing bagasse fly ash, which is waste from a sugar industry in the treatment of heavy metal bearing waste water. In the present work bagasse fly ash has been used for the treatment of heavy metals like Cd(II) and Zn(II) which are chief constituent in the effluents of electroplating industry. This work also includes the utilization of bagasse fly ash in the treatment of Zn and Cd bearing waste water from electroplating industry waste effluents. Batch studies were conducted for the effect of contact time, adsorbent dose and initial concentration on removal of Cd (II) and Zn(II). Langmuir and Fruendlich isotherms have also been presented. Kinetics of removal of Cadmium and zinc by bagasse fly ash from synthetic waste water has also been presented. Cadmium and Zinc removals were calculated up to 97% and 92% respectively using bagasse fly ash. Kinetics of removal calculated shows applicability of first order kinetics.
