Realising financial value through energy generation from treatment of sewage sludge and optimising operational performance for wastewater plants are two key drivers for water utilities. Optimising the treatment process requires a balance of increased primary solids removal, reduced load on secondary treatment processes, and assessment of effect on biogas yield from treatment of those solids.
Outputs from optimisation studies will provide information to assess the business case for investing in operational activities to improve the biogas yield. UKWIR commissioned the development of a model that enables changes in primary sludge solids capture to be quantified. The model is a spreadsheet tool which allows the assessment of the impact of operational changes to primary treatment processes.
Site operational data are necessary to configure and validate the model, to establish the baseline conditions against which projected variations to the primary treatment process can be assessed. The model was tested (trialled) on two working UK WwTWs.
