Özet
Ammonia is very toxic chemical and it can be removed by air stripping at high pH. JLRs have found applications in wastewater treatment processes due to their high mass transfer rates. In JLRs, intrinsic high turbulence result in a very large air-liquid surface area for greater mass transfer. Therefore, in this study, ammonia removal by air stripping from synthetically prepared ammonia solution at the high pH in a semi-batch JLR due to its high mass transfer capabilities have been investigated. Investigated parameters in a JLR were initial ammonia concentration (10-500mg/L), temperature (20-50°C), air flow rate (5-50L/min) and liquid circulation rate (35-50L/min). While it was demonstrated that temperature and air flow rate have a significant effect on the ammonia removal, it was determined that initial ammonia concentration and liquid circulation rate have no significant effect on the ammonia removal. The overall volumetric mass transfer coefficients (K La) have been calculated from obtained model and it was determined that increasing temperature and air flow rate have a very significant effect on K La. It was concluded that JLR provides higher mass transfer capabilities than other type of reactors even if less air is given. © 2011 The Korean Society of Industrial and Engineering Chemistry.
