Abstract

In todays world as the phase of industrialization is increasing rapidly the need for effective measures for the treatment of ammonia removal from waste effluents of urea fertilizer plant is increasing. Air stripping is the most simple method of ammonia removal from fertilizer wastewaters. Herein, studies were carried out for the removal and recovery of ammonia. With experimental data, a nomogram was generated relating the three controllable variables, namely wastewater flow rate, air flow rate and percentage ammonia removal. It was found that one liter of commercially available raw grade phosphoric acid was sufficient to absorb the ammonia stripped out from more than 275 liters of wastewater having an influent ammonia concentration 2000 mgl-1.
