Influent Models 68 WASTEWATER INFLUENT MODELS The influent models available in GPS-X depend on the model library and the local biological model used to relate the state variables to the composite variables. The manner in which the state variables are calculated sometimes differs from model to model and library to library. This chapter discusses the models available and the flow choices available with the batch influent object. Figure 5-6 - The Influent Models (Panel A - Wastewater, Panel B - Chemical Dosage) Each influent model calculates a complete set of library-dependent state variables that are passed to the rest of the plant layout. The influent models differ only in the type of information required as inputs to the model. The descriptions of the influent models that follow are an overview of how they work; however, due to their complexity and their dependence on the local biological model, and the library currently in use, users are referred to the Influent Advisor to understand the calculations being made in each model. BODbased The BODbased influent model is the choice when BOD data is available and COD data is not available; however, due to the approximations and the nature of the BOD measurement, special care must be taken to properly estimate influent particulate inerts. If this model is selected, the user inputs total carbonaceous BOD 5, total TKN, total suspended solids, a few state variables. The state variables are normally zero, except for the soluble inert organics, soluble ortho-phosphate (CNPLIB) and alkalinity (Figure 5-7 and Figure 5-8 and several stoichiometric fractions). GPS-X Technical Reference
69 Influent Models These inputs are used to calculate the remaining influent state variables: readily biodegradable substrate (ss), slowly biodegradable substrate (xs), particulate inert organics (xi), free and ionized ammonia (snh), particulate biodegradable organic nitrogen (xnd), and soluble biodegradable organic nitrogen (snd). Figure 5-7 - CN Library BODbased Influent Model Inputs The relationships between the six calculated state variables and the composite and stoichiometric fractions are library-specific and the relationships are shown in the appendix to this chapter (Figure 5-23 and Figure 5-24). BODultimate is assumed to be equivalent to the biodegradable COD and therefore has units of mg COD/L. GPS-X Technical Reference
