Introduction to Sludge Treatment

The residue that accumulates in sewage treatment plants is called sludge or biosolids. Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. 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.

EGLE has the responsibility to protect the public health and the environment by ensuring wastewater is properly handled and treated safely.

Physicochemical Treatment Processes pp Cite as. Sludge accumulates as a residue in all sorts of wastewater treatment. Sludge comprises the solids and colloids separated from wastewater as well as substances from biological and chemical operation units. Some sludges are produced during wastewater treatment, including primary sludge, which comprises settleable solids removed from the primary clarifier, and secondary sludge, which comprises biological solids generated in the secondary wastewater treatment plant. Figure 1 illustrates a waste activated sludge sample collected from a local sewage treatment works. Furthermore, drinking water producers produce coagulated solids-coagulant matrix, which contains all of the impurities in the raw water and the dosed coagulant. Additionally, numerous kinds of industrial sludges exist which are generated from treating different industrial wastewaters.
