Sludge

Sludge is a semi-solid or solid residue that is generated from wastewater treatment processes. Sludge is typically composed of organic and inorganic materials such as human and animal waste, food scraps, and other debris that is removed from wastewater during treatment.

Sludge can be generated from various sources such as domestic and industrial wastewater treatment plants, water treatment plants, and other sources that produce wastewater. It can contain a range of pollutants including pathogens, heavy metals, organic compounds, and other contaminants that can be harmful to the environment and public health if not disposed of properly.

The proper disposal of sludge is important to prevent contamination of soil and water resources.
