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.
