Removal of Heavy Metal by using Hatchery Residual Bio Sorbent

Water is essential to all forms of life and makes up 50-96 % of the weight of all plants and animals. In recent years pollution of aquatic environment by heavy metals has increased. The continuous mixing of industrial effluents containing heavy metals discharged to the natural resources, deposits toxic compounds in natural water. Due to their potential toxic effect and ability to bioaccumilate, it is very difficult to remove them from wastewater stream. Electroplating industry is one of the potential source of heavy metal containing waste water. Even though conventional processes were witnessed for the treatment of this wastewater it still contains rational concentration of heavy metals so it is very necessary to affix supplementary treatment processes. The removal of Cu and Cd was investigated by using hatchery residual biosorbent. The effects of contact time, HRB dosage concentration and pH for the electroplating industry effluent was studied at lab scale by conducting batch experiments. The maximum adsorption capacity for Cd was 115.02 mg/l for 30gm of HRB dosage.
