Définition
Sens commun

All processes intended to render sewage sludge in compliance with environmental standards, land use regulations or other applicable quality standards for recycling or reuse. Primary, secondary and tertiary treatment is usually distinguished. These treatments not only reduce the volume of residues, but also stabilize and transform them into environmentally acceptable components and useful by-products. Tertiary treatment includes, for example, chemical conditioning, disinfection, pressure filtration, vacuum filtration, centrifugation and incineration. It is possible to classify wastewater treatment and sludge treatment in different categories, namely secondary treatment for wastewater and tertiary treatment for sewage sludge.
