Engineers at Veolia Water Solutions & Technologies have developed a software package, OCEAN, which will help change our approach to municipal wastewater treatment. A sewage treatment plant should no longer be viewed as a disposal facility. It can be an opportunity to generate energy, recover resources, and recycle water thus reducing our reliance on fresh water supplies. OCEAN can contribute to this by, for example, identifying energy-saving solutions and changing wastewater treatment from a net importer of resources into a net exporter.

“Raw sewage has a potential to generate 0.6 kW/m3, but most of this is lost in the treatment process” says Kieran Healey of Veolia, “With a typical plant consuming 0.3 – 0.4 kW/m3 of raw wastewater treated, there is clearly potential for improving energy sustainability.” But to achieve this improvement we need to know how the various treatment process units interact with each other so that we can identify options – retrofits like improved process control or capital investments like thermal hydrolysis. OCEAN calculates energy balances, sludge production and carbon dioxide emissions so that we can evaluate these options quickly and easily.

The inputs to the software are the treatment process units, the design loads and the operating parameters. Using benchmark data collected from over 3,500 Veolia municipal wastewater treatment plants around the world, OCEAN constructs a plant model including chemical consumption, sludge production, energy balance and carbon dioxide emissions. OCEAN displays these graphically so that alternatives can then be quickly compared against the current parameters to assess potential performance improvements and cost savings
