How is Sludge Extracted During Wastewater Treatment?
Before being used for irrigation, returned to a body of water or reused, wastewater undergoes a multi-stage cleaning process. This treatment process produces two types of waste—sewage waste and industrial sludge—that must be managed as special waste.
  • During sewage treatment, debris such as sticks, sand, coffee grounds and eggshells are screened out and separated to protect the treatment facility equipment. The collected debris is usually disposed of in a landfill. Next, the wastewater undergoes a biological treatment process to remove dissolved organic matter. The process causes microorganisms in the water to grow in size and number until they’re suspended and can be settled out as sludge. The solids are collected and receive further treatment as sewage waste.
  • During industrial wastewater treatment, coolant waters, cleaning water and processing waters are similarly settled, clarified and centrifuged to remove solids and greases. This material is categorized as industrial sludge.
