Energy Management | Doosan Enpure

 

Many wastewater streams, including municipal sewage, carry significant chemical energy in the form of suspended and dissolved organic materials. Traditional treatment processes use energy to aerate and oxidise these organic pollutants, the whole process being a net energy user. By careful process selection and design it can be possible to minimise the energy input to the wastewater treatment and maximise energy recovery to make the whole process energy neutral. The Sankey diagrams below show the energy fluxes for two different treatment processes: a traditional extended aeration plant combined with conventional anaerobic digestion and, as a comparison, a plant using high efficiency primary settlement combined with high efficiency digestion incorporating ultrasonic cell lysis (sonixTM)
