Abstract: Textile industries uses a numerous amount of heavy metals in different processes and significant losses during the process and are discharged in the effluent. With the new advancement and development in world, severe problems including the waste water containing hazardous heavy metals deteriorating the ground water. Only about 8% of industrial waste water is treated before discharge. Use of bio-sorbents for heavy metal removal from wastewater is a cost-effective method due to their nature of agricultural waste. This study use to remove the heavy metals (Cr, Pb and Ni) from wastewater through agriculture based bio-sorbents, rice husk and eggshells of hen. The pretreatment applied to rice husk by treating with formaldehyde for removal of chromium. The pretreatment for egg shells is calcination at 800° C for 2 hours. Bio-sorbents have applied in varied doses like 1g, 2g at temperature between 25°C and 28°C. The maximum efficiency of rice husk is for chromium that is 95% for synthetic solution and 100% for Nickle removal by applying 1g dose to wastewater. The removal efficiency of eggshells is 61% for synthetic solution of lead (Pb). Therefore, it is concluded rice husk is more efficient as bio-sorbent as compared to eggshells, but removal efficiency of rice husk decreases with increasing doze of rice husk
