Sludge Wastewater Thickener In Water Treatment

High Capacity Rotary Drum Thickener for Chemical Industry DHNS-100

How Rotary Drum Thickening Works:

Rotary drum thickening increases the sludge solids concentration (i.e. thickens the sludge) by agitating the solids in a slowly-rotating vessel with porous walls through which the water (or filtrate)drains.

A rotary drum thickener operates on the principle common to that of a gravity belt thickener. in that water drains from the sludge through a retaining porous medium. For a Rotary drum thickening, the porous medium is the cylindrical wall of a 0.5−1.5 m diameter drum which rotates at speeds between 5 and 20 RPM while the sludge continually passes through it.

The porous wall may be fabricated from a range of materials, including polymers, steel, and ceramics. A spray system is used to clean the drum and prevent the pores from blocking.

Rotary drum thickening can achieve solids concentrations up to 9% and corresponding solids recoveries of 90−99%, depending on the sludge source and the condition employed. Conditioning by polymer dosing is normally conducted in a mixing drum upstream of the Rotary drum thickening.

Peripheral Configuration:

Applications:

• Pulp and Paper: Rotary drum thickeners find application in the pulp and paper industry for sludge thickening prior to further processing or disposal. This helps reduce water content in the sludge and improve efficiency in downstream processes.

• Food and Beverage: In food and beverage production, rotary drum thickeners are utilized for the thickening of food waste slurry, fruit and vegetable processing waste, and other organic byproducts. This aids in waste management and resource recovery.
• Textile and Dyeing: Rotary drum thickeners are employed in the textile and dyeing industry to thicken and dewater wastewater generated during the production processes. This assists in reducing water consumption and minimizing environmental impact.
