Influence of Ammonia Stripping Parameters on the Efficiency and Mass Transfer Rate of Ammonia Removal

This study analyzed the influence of different ammonia stripping parameters on removal efficiency and mass transfer rate. Ammonia was performed two devices, a column packed tower, with artificial ammonium hydroxide wastewater. First, concentration pH were varied in without liquid circulation. At same pH, rate constant, irrespective initial concentration. When increased, fraction also resulting higher Second, effects assessed using tower fluid The did not affect or Furthermore, at apparatus liquid-gas ratios 26.8–107.2 L/m3, lower ratio led to increased Conversely, ratio, greater air consumption. In conclusion, considering volume supply, range optimal determined as 26.8–53.6 L/m3. particular, 26.8 L/m3 condition achieved best 63.0% through only 6 h 70 °C 8.5.
