Abstract

The focus of this MSc Project was to design and implement a fully adaptable modular whole life costing model for use within wastewater systems with different resource recovery methods. The model takes the format of an Excel spreadsheet which compares the potential profitability of implementing three resource recovery methods: Surface Filtration, High Loaded Activated Sludge and Reverse Osmosis. Surface Filtration has been included as a baseline scenario so the other two recovery methods can be compared against it.
The data used in the model is a range of secondary data from multiple sources which have all been updated and adjusted to fit the project parameters. In summary the results of the model show that out of the two resource recovery methods, Reverse Osmosis is predicted to be the only profitable recovery method as High Loaded Activated Sludge’s electrical consumption and capital costs are too large to be surmounted by the income potential from selling the reclaimed Phosphorous. A further explanation and criticism of the data is explored in the Analysis chapter before the ultimate conclusion that for now that only Reverse Osmosis is a profitable method of resource recovery, however following further research and potential technological advances, the extraction of Phosphorus should become profitable in the future.
