Abstract [en]

Can wastewater treatment contribute to counteract global warming? Increased biogasproduction for substituting fossil fuel is one possibility. However, using maximum amount of thecarbon source for biogas production there will be no carbon source for biological nutrient removal.This will need development of new methods for nutrient removal without carbon source, for whichstruvite precipitation and can anammox be used. Ozone treatment of digested sludge afterdegassing of CO2 with recycling back to the digestion is a promising method to increase biogasproduction from sludge digestion.At anaerobic digestion half of the energy is utilized as biogas and half remains as organic materialin the digested sludge. To eliminate emission of greenhouse gases from digested sludge, allorganic content in the sludge should be oxidized. At Super Critical Water Oxidation SCWO allorganic content is oxidized and the energy can be utilized.The possibility to use sewage sludge to counteract global warming by recycling carbon to deep seesediments should be studied.
