Sludge - Wikipedia 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
Wastewater treatment - Sludge, Disposal, Treatment | Britannica Two basic goals of treating sludge before final disposal are to reduce its volume and to stabilize the organic materials Stabilized sludge does not have an offensive odour and can be handled without causing a nuisance or health hazard Smaller sludge volume reduces the costs of pumping and storage Treatment methods
What Is Sewage Sludge and What Can Be Done with It? - Penn State Extension What Is Sewage Sludge and What Can Be Done with It? In this document, "sewage sludge" will refer to wastewater treatment solids generally, and "biosolids" will refer specifically to material that is suitable for land application
Basic Information about Sewage Sludge and Biosolids When domestic sewage is transported and conveyed to a wastewater treatment plant (WWTP), it is treated to separate liquids from the solids, which produces a semi-solid, nutrient-rich product known as sewage sludge
Sludge: Types, Uses, Objectives and Methods of Removing Sludge 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
Sludge In Wastewater Treatment - Water Wastewater Sludge, in the context of wastewater treatment, refers to the semi-solid residue produced during the treatment process Specifically, it includes organic and inorganic material, suspended solids, bacteria, and pathogens
What is sludge? | The MBR Site - Sludge Processing Regardless of its origins, sludge contains water, dissolved organic and inorganic materials and suspended solids The suspended solids normally make up 2−5% of the sludge for municipal wastewater sludge A key part of sludge treatment is the reduction of its volume by reducing the water content The water in sludge exists in various forms:
What is Sludge, and How is it treated? - Environmental XPRT 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
Sludge: Meaning, Properties and Disposal | Sanitary Engineering The sludge is unsafe because it contains pathogens and it decomposes rapidly and serves as food for saprophytic organisms Therefore, the primary objective of the sludge treatment should include its safe removal from the treatment works at reasonable economy and safety of the public health
