Explanation:
- 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 or Semi-solids such as faeces that settle down during wastewater treatment are called sludge.
Explain
- Sludge is human waste (like faeces) in waste water left during sewage treatment. Since it is organic waste, it is used to produce biogas and manure. Sludge is collected by a scrapper.
