Abstract

The study was conducted to observe the effectiveness and the efficiency of the adsorption method to remove ammonia from sewage water. The experimental design involves fixed-bed column, desorption and regeneration study. The results showed that the modified sand performed better in removing ammonia from sewage compared with pristine sand and regenerated used modified sand. The experimental data showed a better fit to the Thomas and Yoon-Nelson adsorption models. We found that the modified sand removed ammonia up to 99% and remained 80% of removal after 50 minutes compared to the pristine sand that was only 78.51% and gradually dropped to 10% after 50 minutes. Modified sand recorded the maximum adsorption capacity of 0.014 mg/g compared to 0.0033 mg/g for pristine sand and 0.0087 mg/g for regenerated used modified sand. Modified sand was able to be reused using a relatively low cost regenerating solution (NaCl).
