INTRODUCTION
Ln uses the term "sludge" to refer to all liquid, pasty or solid waste from wastewater treatment plants. Sewage sludge refers to all concentrated phases resulting from phase separation operations (settling, thickening, filtration, dewatering, etc.) in wastewater treatment.
A wastewater treatment plant produces around 2–3 m 3 per 1,000 inhabitants every day. The sludge extracted contains a high proportion of organic matter and is therefore fermentable. Depending on its intended use, the sludge is treated and conditioned to reduce its volume and ensure stabilization and hygienization.
This chapter presents a wide range of current sludge treatment and recovery techniques.
