In this paper a mathematical steady-state model for the design of the pre-denitrification system is proposed. This model takes into account four substrates (soluble and particulate biodegradable organic matter, ammonia nitrogen and nitrate nitrogen) and extends a previous version proposed by Esposito et al. (2003), considering the biomass decay. This tool makes it possible: i) to define the applicability of the pre-denitrification system; ii) to solve completely the design problem, with explicit expressions of the biological reactor volumes. Model applications show the increase of the oxidation phase volume, which is necessary either to face a higher influent organic load or to achieve a higher nitrogen ammonia removal.

Abstract
In this paper a mathematical steady-state model for the design of the pre-denitrification system is proposed. This model takes into account four substrates (soluble and particulate biodegradable organic matter, ammonia nitrogen and nitrate nitrogen) and extends a previous version proposed by Esposito et al.

This tool makes it possible: i) to define the applicability of the pre-denitrification system; ii) to solve completely the design problem, with explicit expressions of the biological reactor volumes. Model applications show the increase of the oxidation phase volume, which is necessary either to face a higher influent organic load or to achieve a higher nitrogen ammonia removal.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
