Ammonia stripping performance is highly dependent on the column temperature and steam to wastewater ratio. Efficiency decreases significantly as column temperature decreases. The maximum ammonia transfer efficiency of about 96 percent was achieved at pH 12 in continuous packed column which was much higher compared to 81 percent efficiency achieved in batch-wise stripping of ammonia.
