WebbIt is also very easy to concentrate this type of sludge with a static thickening step just befo-re dewatering. The drawback is that this sludge ferments very easily. 1.2.2. Biological sludge: Biological sludge comes from the biological treatmentof the wastewater. It is made of a mixture of microorganisms.
WebbSoftener sludge is rarely thickened because it concentrates well in the clarifiers. If necessary, it can be further thickened to 20–30% w/w or more at a dry solids loading rate of about 8 kg/h.m 2. To prevent the softener sludge becoming too thick, underflow is sometimes recycled to the feed. steve ringer feeder fishing youtubeWebb18 juni 2024 · A gravity sludge thickener has the same design features as a primary sedimentation tank used for wastewater treatment, and most often has cylindrical … steve ringer fishing youtubeWebbThe design of a gravity sludge thickener is determined by the maximum solids loading rate .
