Application of biofilm kinetics to the sulfur/lime packed bed reactor for autotrophic denitrification of groundwater

To evaluate the engineering feasibility of autotrophic denitrification, a program of theoretical and experimental investigations of the granular sulfur/lime packed bed autotrophic denitrification system was planned and completed. This program evaluated the stoichiometric, kinetic and physical characteristics of the process. This paper will focus on the results of that project which are concerned with the kinetics of autotrophic denitrification of groundwater.
