Energy Footprint Modelling: a tool for process optimisation in Large Wastewater Treatment Plants

In wastewater treatment modelling, energy information is not always immediately available. More detailed energy information on a unit process level can be used to calibrate energy balance models serving for quantification of larger energy savings. Modelling energy footprint has lower uncertainty than other greenhouse gas equivalent footprint models, and is the prime candidate for minimising costs and environmental impact. Due to their magnitude, and their larger number of equipment units, large wastewater treatment plants are associated with the largest margin for improvement.
