Development in various industries is essential to mankind, but also it seems to possess a serious threat to the environment and humanity. The effluents are discharged into the land and water bodies, which is responsible for the destruction of aquatic creatures. Heavy metals are the major factors responsible for water contamination. Traditional treatment methods like microfiltration, ultrafiltration, Nanofiltration, reverse osmosis, etc., are a monotonous and painstaking processes, and it also adds on to the capital cost. Bio sorption is such a method that employs living organisms or parts of them to remove metals. Bacteria, fungi, and algae are proven to be efficient biosorbents. Extracellular Polymer Substances(EPS) are bacterial secretions that have shown to be potential biosorbents. This paper acknowledge on the metal complex formation capability of EPS extracted from wastewater. The advantage of an EPS in the biotreatment of heavy metals is studied with the optimization of the process parameter. The viability of adsorption and desorption behavior of EPS /sodium alginate(SA) bead prepared in a 2:8 ratio for Ni removal has been investigated through batch studies. The optimal condition for adsorption is found to be pH:6.5; adsorbent dose:6g; initial metal concentration: 75 mg/L and temperature:40�C
