WebbSludge dewatering – Dewatering differs from thickening in that the sludge should behave as a solid after it has been dewatered. Dewatering is seldom used as an intermediate process unless the sludge is to be incinerated and most wastewater plants use dewatering as a final method of volume reduction before ultimate disposal. WebbSludge Thickening Methods. In primary or secondary treatment of wastewater, mechanical sludge thickening of sludge from clarifiers has become the industry norm prior to digestion or dewatering. Alfa Laval’s sludge thickening machines all have enclosed designs plus very low maintenance and odour control requirements:

WebbAll HUBER thickening systems guarantee an adjustable final solids content and meet the highest separation requirements. With regard to the economical further treatment and disposal of sewage sludge, it is necessary to reduce the sludge volumes produced within the course of the wastewater treatment process. WebbSludge thickening methods are usually physical in nature: they include gravity settling, flotation, centrifugation and gravity belts. Gravity Thickening A gravity thickener is similar to a conventional circular sedimentation basin. Dilute sludge is fed to a centre feed well and allowed to settle and

There are two main methods of disposal: landfills or incineration. In landfills, the dewatered sludge is buried underground in a sanitary landfill. Depending on the sludge’s chemical composition, it can also be used as a soil conditioner or fertiliser.

WebbSludge dewatering is making the sludge more condensed and dehydrated so that powder can be produced of sludge and also sludge cake. We can also utilize it as a land filler, for agricultural purposes, and landscaping. In the first step of the sludge treatment process i.e. the sludge thickening process, the moisture content will reduce up to 90%.

Webbbatch processes. Gravity thickeners are essentially settling tanks with or without mechanical thickening devices (picket fence type). Plain settling tanks can produce solids contents in sludges of up to 8.0 percent for primary sludges and up to 2.2 percent for activated sludge.
