ABSTRACT
The aim of this research was to achieve a better understanding of nitrification under saline conditions. The research was carried out in two phases. In the first phase, laboratory scale activities were conducted to obtain fundamental data to determine the relationship between salinity and nitrification. In the second phase the results collected from the laboratory experiments were compared and validated with the results collected from full-scale treatment plants. Modelling was employed in both phases to provide a mathematical description for salt inhibition on nitrification and to facilitate the comparison. The research has lead to an improved understanding of the effect of salinity on nitrification, while subjects for further research were also identified. The research findings and challenges are described in more detail below.
