Abstract: | Lead concentration in watewaters discharges by various industries generally varies from 0.4 mg/1 to 400 mg/1. Out of various removal methodoligists, adsorption operation has been seen as a suitable method of treatment of such wastewaters. Therefore, the efficiency of wood charcoal, available locally at Roorkee, in removing lead from wastewaters in a continuous operating adsorption system is studied in this investigation. Locally available charcoal offers advantages over the commercially used adsorbents, which are costly and requires periodic regeneration. The present investigation has dealt with the adsorptive response of the charcoal particles for lead ions to the changes in operating parameters; the charcoal mass flow rate, the lead ions concentration and the flow rate of influent stream into the reactor, The charcoal mass flow rate ranges from 12.5 g/min to 26.1 g/min, the lead ions concentration in influent stream from 5 mg/1 to 15 mg/I and the flow rate of influent stream from 0.25 1/min to 1.00 1/min. Moving media adsorption system using charcoal as adsorbent has succeeded in the removal of lead ions from wastewaters. The percent removal efficiency of lead is found to be 78% to 99% depending upon the values of the. above operating parameters. Based on the experimental data obtained in the present investigation, the correlation relating equilibrium concentration of effluent stream, Ce to the operating parameters, the charcoal mass flow rate, W,the influent flow rate, (:), and the lead ions concentration of influent stream, Co, has been recommended as hereunder... |
