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 (KLa) have been calculated from obtained
model and it was determined that increasing temperature and air flow rate have a very significant effect
on KLa. It was concluded that JLR provides higher mass transfer capabilities than other type of reactors
even if less air is given.
