Answer:
Sludge:
Sludge is a semi-solid slurry that can be produced from a range of industrial processes, from water treatment, wastewater treatment or on-site sanitation systems. For example, it can be produced as a settled suspension obtained from conventional drinking water treatment, as sewage sludge from wastewater treatment processes or as fecal sludge from pit latrines and septic tanks. The term is also sometimes used as a generic term for solids separated from suspension in a liquid; this 'soupy' material usually contains significant quantities of 'interstitial' water (between the solid particles). Sludge can consist of a variety of particles, such as animal manure.
Sanitation:
Sanitation refers to public health conditions related to clean drinking water and adequate treatment and disposal of human excreta and sewage. ... A sanitation system includes the capture, storage, transport, treatment and disposal or reuse of human excreta and wastewater.
