High-Performance Rotary Drum Thickener for Sludge Pre-Treatment DHNS-5
How Rotary Drum Thickening Works:
By agitating the solids in a slowly-rotating vessel with porous walls, rotary drum thickening effectively increases the sludge solids concentration, resulting in sludge thickening. The principle behind rotary drum thickening is similar to that of a gravity belt thickener, where water drains from the sludge through a retaining porous medium.
In the case of rotary drum thickening, the cylindrical wall of a drum with a diameter ranging from 0.5 to 1.5 meters serves as the porous medium. The sludge continually passes through the rotating drum, which operates at speeds between 5 and 20 RPM.
The porous wall can be fabricated from various materials, including polymers, steel, and ceramics. To prevent the pores from blocking, a spray system is used to clean the drum.
Depending on the sludge source and the conditions employed, rotary drum thickening can achieve solids concentrations up to 9% and corresponding solids recoveries ranging from 90% to 99%. Typically, polymer dosing for conditioning is conducted in a mixing drum upstream of the rotary drum thickening process.
Peripheral Configuration:
Applications:
-
Municipal Wastewater Treatment: The high-performance rotary drum thickener is extensively employed in municipal wastewater treatment plants. It efficiently thickens the primary and secondary sludge, reducing the volume for further processing and disposal.
-
Industrial Wastewater Treatment: Industries such as chemical, pharmaceutical, textile, and pulp and paper utilize high-performance rotary drum thickeners for sludge pre-treatment. It effectively separates solids from the wastewater, enabling better treatment and disposal of industrial waste sludge.
-
Mining and Mineral Processing: In the mining and mineral processing industry, the high-performance rotary drum thickener is used for the thickening of tailings, which are the byproducts of ore processing. This aids in minimizing water content and facilitating proper disposal and storage of thickened tailings.
