Sludge exists in a solid or semi-solid state and is a by-product of wastewater treatment, sewage treatment, water treatment, or on-site sanitation systems. Its production is either primary or secondary, meaning there is primary sludge and secondary sludge.
The meaning of SLUDGE is mud, mire; especially : a muddy deposit (as on a riverbed) : ooze. How to use sludge in a sentence.
Sludge (possibly from Middle English slutch 'mud, mire', or some dialect related to slush) [1] is a semi-solid slurry that can be produced from a range of industrial processes, from water treatment, wastewater treatment or on-site sanitation systems.
Water treatment is a process designed to remove contaminants from water, making it safe for various uses or returning it to the environment in a cleaner state. This complex purification journey inevitably generates a semi-solid byproduct known as sludge.
Wastewater treatment - Sludge, Disposal, 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.
Sewage sludge is the residual, semi-solid material that is produced as a by-product during sewage treatment of industrial or municipal wastewater. The term "septage" also refers to sludge from simple wastewater treatment but is connected to simple on-site sanitation systems, such as septic tanks.
Sludge is a by-product of the wastewater treatment process, consisting of organic and inorganic solids suspended in water. Sludge treatment entails various processes and techniques depending on the sludge’s source and existing contamination levels.
The term is intended to distinguish high-quality, treated sewage sludge from raw sewage sludge and from sewage sludge that contains large quantities of environmental pollutants.
