Industrial sludge is the solid residue separated from wastewater during treatment processes in factories. If not properly managed, it can affect treatment system efficiency and pose environmental risks.
Sludge can be classified as non-hazardous, such as waste from food processing or biological treatment systems, and hazardous, such as waste from metal or chemical industries. Proper analysis is required before disposal to determine the appropriate treatment method.
Management options include secure landfill disposal, energy recovery through incineration, conversion into soil conditioners (for non-contaminated sludge), and reuse in industrial applications.
Proper sludge management reduces environmental risks and supports sustainable resource utilization.
