Incineration

Incineration − or combustion − of sewage sludge is the most widely-implemented alternative end disposal method after land spreading. It oxidatively converts the organic carbon, nitrogen, sulphur, nitrogen and phosphorus into gaseous and predominantly mineral solid products. It is effective in eliminating the feed organics, produces little odour, and generates a stable solid ash product which is stable and reusable. The heat generated can be recovered from the flue gas stream and reused directly and/or converted to electrical power.

Combined hydrothermal carbonization with anaerobic digestion: recycling of the HTC products

Recycling the product streams from a hydrothermal carbonisation process to the anaerobic digester promotes biogas yield in terms of methane volume per unit feed COD, using HTC process conditions of 190 °C and a 1 h reaction time, this research suggests.
