Presence of nickel in wastewater adversely affects man and environment. The higher concentration of nickel causes poisoning effect like headache, dizziness, nausea, dry cough, vomiting, chest pain, rapid respiration, cyanosis and extreme weakness. Activated sludge has biological adsorptive properties. Dry activated sludge has been proved to be effective biosorbent. Present research is aimed at studying use of wet activated sludge for nickel removal. Also optimum values for sorbent dose, contact time and initial concentration are reported. The behaviour of activated sludge with respect to nickel removal was as expected. With initial increase in adsorbent dosage, rise in nickel removal was observed. There after it was followed by constant removal and then slight drop. For contact time, the nickel removal increased rapidly initially and then it became gradual. The initial nickel concentration had positive effect on nickel removal, but the percentage removal drops. Considering concentration profile of treated effluent at various initial concentrations, 1000 mg/l was considered as optimum concentration.
