Sludge and Biosolids - Idaho Department of Environmental Quality
Sludge and Biosolids. Sludge is the solid semisolid or liquid untreated residue created during the wastewater treatment process. When treated and processed sludge becomes biosolids which are the stabilized residuals that settle from the water during the treatment process. Biosolids may be disposed of or beneficially used.
Sludge thickening and dewatering - SUEZ Group
Two processes can be used to thicken sludge: Static thickening by gravitational settling Static thickening calls on conventional and innovative techniques such as Drainis Turbo that eliminates the water at speeds higher than the conventional speeds thereby optimising the downstream dewatering phase reduction of the amount of equipment energy and reagent consumption etc. .
Sewage sludge - Waste - Environment - European Commission
Introduction. Sludge originates from the process of treatment of waste water. Due to the physical-chemical processes involved in the treatment the sludge tends to concentrate heavy metals and poorly biodegradable trace organic compounds as well as potentially pathogenic organisms viruses bacteria etc present in waste waters.
Sludge is an organic solid semi-solid or liquid by-product of publicly owned treatment works. For infomation about waste resulting from industrial processes please contact the Waste Management Program. Sludge characteristics vary depending on each treatment facility& 39;s wastestream and the processes that are used.
