What is the Sludge Thickening Process in Water Treatment ...

06-03-2018· Sludge thickening is an important process in treating solid waste. It minimizes the water waste, enabling the re-treatment of biosolids so that they can safely circulate back to waterways. It is vital to use the correct product and municipal wastewater treatment solution, so having an expert on hand will give your company the safeguards of dealing with the process in a safe manner.

Sludge thickening is a a low investment process used commonly in wastewater treatment plants to remove as much water as possible from the liquid sludge. The method involves increasing the concentration of the solids in the sludge so that they can be easily dewatered.

Sludge thickening and dewatering - SUEZ Group

Thickening is essential in order to reduce the volume of the sludge produced by wastewater treatment. It optimises the following conditioning, stabilisation and dewatering phases by reducing the size of facilities and equipment, and the operating costs. Dewatering improves efficiency and optimises operating costs.

Thickening of sludge increases its solids content and reduces the volume of free water thereby minimizing the unit load on downstream processes such as digestion and dewatering. The most commonly used thickening processes include gravity thickening, dissolved …

Wastewater treatment - Sludge treatment and disposal ...

13-09-2020· Thickening is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water. Thickening is usually accomplished in a tank called a gravity thickener. A thickener can reduce the total volume of sludge to less than half the original volume.

Sludge Thickening - an overview | ScienceDirect Topics

Thickened sludge may be piped or tankered to a sewage works. Coagulant sludge may aid primary sedimentation of the sewage, thus reducing the solids load to the subsequent biological stages and helping in the removal of phosphate. Thickened waterworks sludge may also be mixed with digested sewage sludge for disposal.

Wastewater treatment - Sludge treatment and disposal ...

13-09-2020· Wastewater treatment - Wastewater treatment - 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 processes. This residue is commonly classified as primary and secondary sludge.

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.).
