The sludge should be well digested without any appreciable amount of raw or undigested mixed with it Either wet or partially dewatered sludge, such as obtained from drying beds or vacuum filters can be used to fill low areas Where wet sludge is used the area becomes a sludge ,
different processing methods for drying of sludge 72 Conditions for Drying of Sludge - Amounts and Drying Rates Basically, there are no specific pre-conditions to be fulfilled in order to apply drying This means that all known sludges from munici-pal waste water treatment plants may be processed in a properly designed and oper-ated drying .
% Moisture = Wet Sludge - Dry Solids x 100 Wet Sludge % Volatile Solids = Dry Sample - Ash x 100 Dry Sample % Reduction in Volatile Matter = In - Out x 100 In - (In x Out) CLARIFIER Detention Time = Volume Weir Overflow Rate = Flow Flow Rate Length Surface Settling Rate = Flow .

Sludge treatment and disposal 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 process This residue is commonly classified as primary and secondary sludge
Different textile sludge/clay mixture (05% to 525% dry sludge) were used to make fired clay-bricks, which were evaluated in terms of their compressive strengths, leaching behaviour, water absorption and shrinkage percentage The textile sludge incorporated clay fired bricks showed up to 77% more compressive strength compared to
