Patil College of Engineering, Akurdi, Pune 44, India Abstract: Environmental pollution by toxic heavy metal contamination due to rapid industrialization is a challenging problem for maintaining the quality and hygiene of water. The discharges of industrial effluents into aquatic environment cause a potential threat to the aquatic life as well as human health, which is a matter of great concern due to their toxic nature and adverse effect. Techniques used to remove heavy metal are namely physical, chemical and biological treatment. Biosorption is a recent eco-friendly technique which gained importance in this decade. The process of Biosorption has many attractive features compared to the conventional method. The present study investigates that successful use of eco-friendly adsorbents Banana peels and Fish scales. Banana peel which is a discarded fruit waste and Fish scales which are readily available waste in the market were used to prepare environment benign bio- adsorbent for the adsorption of impurities from aqueous solution. Banana peels and fish scales were washed, dried and ground to 150- 200 μm and to 160 μm respectively, before being used for treatment of pharmaceutical waste water. The combination of both these biosorbent was used for treatment of waste water with different proportion of adsorbents, variation of pH and contact time. It is found that the maximum efficiency of removal of heavy metal is 60% and 70%respectively. Keywords: Banana Peel, Bio-adsorbent, Fish Scale, Industrial Effluents, Wastewater Treatment. 1. Introduction India is a developing country with an increasing population density. In order to develop its economy, India requires establishment of new industries. Due to unplanned industrial growth, much of the land and nearby water bodies are polluted by indiscriminate dumping of solid and liquid wastes generated by these units. Increase in the levels of metal ions and organic pollutants in the environment are either due to absence of laws for various industries to treat their wastes or if there are laws, there is no strict enforcement by the Ministry of Environment and other regulatory authorities in India. Land contaminated by heavy metals is increasingly becoming an environmental, health, economic and planning issue in the India. Eco-toxicity due to polluted water sources affect on living organisms has become a main concern for the last few decades. Due to rapid industrialization and substantial urbanization, the waste effluents get discharge directly in river water causing pollution to environment [1]. Heavy metals are an important class of environmental pollutants.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
