X-ray diffraction along with infrared and X-ray photoelectron spectroscopy verified the effective heterojunction.
However, successful formation of anatase TiO 2 and g-CN was observed when a two-step calcination route was followed, i.e., via synthesis of anatase TiO 2 from dried sludge, and later development of heterojunction by calcining the TiO 2 and melamine mixture. Moreover, due to the non-uniform composition of organic content in the dried sludge, it was not easy to control the N doping level by varying melamine content (0-100%) in the precursor mix. Detailed morphological and chemical characterizations showed that the one-step calcination route did not create TiO 2/g-CN composites instead, only N-doped anatase TiO 2 composites were formed. In the initial approach, one-step calcination of dried sludge and melamine mixture was carried out. Two reaction routes of composite formation were evaluated. The feasibility of preparing TiO 2/g-CN heterojunction from Ti-incorporated dried dye wastewater sludge is explored in this study.

From the analysis of these At-Site Flood Frequency Analyses, it was concluded that the normalised peak flow error needed to be less than 10% if reliable design flood quantile estimates were to be obtained.ĭeng, L, Guo, W, Ngo, HH, Zhang, X, Chen, C, Chen, Z, Cheng, D, Ni, S-Q & Wang, Q 2022, 'Recent advances in attached growth membrane bioreactor systems for wastewater treatment', Science of The Total Environment, vol.
The best performing sets of these sets of parameter values were used with SWMM in a continuous simulation mode to predict flow sequences for extraction of Annual Maxima Series for an At-Site Flood Frequency Analysis. Alternative sets of parameter values were used to obtain estimates of the peak flow for each of the selected events. For this purpose, a SWMM-based catchment model was investigated using 25 monitored events, while the assessment of the calibration was based on a normalised peak flow error. The purpose of this paper is to assess the event modelling accuracy needed if data from the calibrated model are to be used for continuous simulation of data for flood frequency analysis.
However, the level of calibration required to achieve reliable design flood estimation remains unspecified. To generate the data needed for estimation of the flood risk, catchment models have been used with the reliability of the predicted catchment response for design flood estimation dependent upon the model calibration. Management of flood risk remains a major problem in many urban environments. Ball, JE 2022, 'Modelling accuracy for urban design flood estimation', Urban Water Journal, vol.
