KTH, Chalmers, IVL, GU

Provide new knowledge on the green house gas (GHG) emissions from wastewater and sludge processes.

Provide good decision support on suitable combinations and operation for such processes to minimize GHG emissions.

Monitoring N2O emissions in the Anammox pilot showed that 0.4 –2% of nitrogen load was converted into N2O.

Through dewatering and recycling of digested sludge.

Ordinary digestion HRT = SRT

HRT is Hydraulic retention timeSRT is Sludge retention time

Improved digestionHRT < SRT

HRT determines reactor volumeSRT determines biogas production
