Although the idea behind the concept being explored here is fairly simple, there is a significant complexity that will be addressed within this section. For this model, the wastewater being treated will be assumed to require a set amount of energy to treat. But the treatment of the wastewater isn’t instantaneous, so that assumed energy is needed throughout the wastewater’s journey and different amounts of that energy will be needed at different times with different processes having different requirements. This will make implementing this idea challenging, which will be discussed in the Discussion section, and introduces difficulties in modelling. To model this method and account for this variation in energy demand throughout the wastewater’s journey through the WWTW a time energy profile will be created showing how the distribution of the energy required to treat the wastewater varies throughout the entire treatment process. The Energy required to treat wastewater section, will quantify the energy needed to treat wastewater at SW WWTW site and the time energy profile section will assess how this is distributed throughout the entire treatment process and create a time energy profile.
