Modeling for Packed Bed Phenol Removal by Low Cost Adsorbent Prepared from Rice Husk

Sunil J. Kulkarni and Jayant P. Kaware

Phenol removal by using packed bed by using low cost adsorbent is practical and efficient method for phenolic waste treatment. Low cost adsorbent prepared from locally available rice husk was used for experiments in packed column and effects of various parameters like initial concentration, flow rate and bed height on break through curve were studied. The experimental data was fitted in three models. Thomas, Yoon Nelson and Adam Bohart models were used for analyzing break through curves. The breaks through curves were best described by Thomas model followed by Yoon Nelson model and Adam Bohart model. It was also observed that various model parameters were affected by the factors like initial concentration, flow rate and bed height
