Primary sludge is generated from chemical precipitation, sedimentation, and other primary processes, whereas secondary sludge is the activated waste biomass resulting from biological treatments. Some sewage plants also receive septage or septic tank solids from household on-site wastewater treatment systems.
Sludge characteristics, including density and water-binding properties, are influenced by particle size and floc-forming bacteria. Categories of Sludge During conventional municipal wastewater treatment, two primary types of sludge are produced, each originating from distinct process stages.
