Rotary Drum Thickener for Municipal Sludge Treatment in Factory, Corrosion Resistant, Good Performance - DHNS Series

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.
