Measurement of composition of organic constituents of municipal wastewater for plant-wide modelling
type: CreativeWork
description: Historically wastewater treatment unit operation models have been developed in isolation. Attempts have been made at creating common platform models, which would allow modellers to speak a common language when researching wastewater treatment modelling. However, few attempts have been made at integrating different models into a plant-wide WWTP simulation model. Increasing pressure towards the optimisation of water treatment systems have prompted investigation into integrated WWTP modelling. The use of different state variables in WWTP unit operation models has meant that modelling incompatibilities exist in the theoretical coupling of certain models. Attempts made towards the development of integrated WWTP models have experienced difficulties due to a number of factors. State variables required in one model may be non-existent in other models, the definition of state variables may be different between different unit process models and compounds that are considered constant in a unit process model may be a state-variable in another unit process model Thus the difficulties in coupling different unit process models are mainly due to differences in state variable meaning and occurrence in different unit process models. Recent approaches towards the development of plant-wide WWTP simulation models have included the continuity based interfacing method (CBIM) of Vanrolleghem et al. (2005) and Volcke et al. (2006), the 'supermodel approach' of Jones &Tákacs (2004 cited in Grau et al 2007) and Seco et al. (2004 cited in Grau et al 2007) , the transformation based approach of Grau et al. (2007) and the mass balances based plant-wide WWTP model approach of Ekama et al. (2006 a,b), Sötemann et al. (2006) and Wentzel et al. (2006). The use of compounds in their elemental composition forms, viz. C, H, O, N, P and charge content, as part of a method to transform incompatible unit process state variables into compatible forms is a general theme in integrated modelling approaches. T…
