ROBERT SIMM is an academic who published a paper in 2004 entitled A conceptual model for apparent free ammonia inhibition in wastewater systems. ROBERT SIMM published this work as part of a team: Simm, Robert. Here is a description of this work: The original hypothesis for this research program was that free hydroxylamine, and not free ammonia, is the true cause of nitrite accumulation in wastewater treatment systems. This hypothesis was developed based .upon the observation that nitrite accumulation appears to be a function of both free ammonia and dissolved oxygen concentration, as well as the work of Yang and Alleman (1992) who demonstrated hydroxylamine production in batch experiments. The starting point of the research program was the development of a suitable hydroxylamine analysis method for wastewater applications. The method developed as part of this thesis combines simplicity, good yields, and a relatively low detection limit. Measurable concentrations of hydroxylamine were not detected in completely stirred tank reactor (CSTR) or sequencing batch reactor (SBR) systems treating s.
