“…Ammonium determination is usually carried out with CFA, FIA, or SIA [8,9]. With the UV/UV procedure two steps of photooxidation are needed [29]. The first one allows the measurement of TKN as shown above.…”

“…Häck and Lorenz (2002) also suggested that the combination of UV absorbance values at 254 nm wavelength and additional suspended solid (SS) measurement could estimate the concentrations of COD and TOC in sewage. However, in case of the nitrogen and phosphorus, chemicals as pretreatment reagents were commonly used for online measurement (Bourgeois et al 2001;Roig et al 2001;Thomas et al 1997), and successful application of UV absorbance value was not reported yet.…”

The objective of this study was to test the feasibility of a new method to improve the accuracy in the estimation of sewage components. Adding to the regression of sewage components with UV (ultraviolet) absorbance values, a proposed method considered an unclear but existing relationship among characteristic of sewage production. Sewage production showed very defined profiles due to the daily human activities. So the main idea was the combination of measuring the UV absorbance values and analyzing the characteristics of the sewage production. For this purpose, 446 sewage samples taken at every 2-h interval for 51 days at a wastewater treatment plant were statistically analyzed using neural network (NN). NN was trained with 350 data sets (about 29 days) of UV absorbance values, flow rate and time. And as a result, it could predict 96 data (12 days) as a validation, indicating that estimation accuracies were improved to higher level than those of the linear regressions. The proposed method could estimate concentrations of total nitrogen (TN) and total phosphate (TP) within practical accuracies as well as total suspended solid.
