FRDT Series Rotary Drum Sludge Thickener

Working principle

The rotary drum sludge thickener’s working principle is very simple; feed the sludge into the dynamic reactor 

through sludge pump, and dosing pump, then it goes to rotary drum inside thickener, the rotary drum with 

compound filter colth will rotate with speed around 10 rmp. after water penetrate the filter cloth, the flocculant

sludge will be holded back on.In order to keep the filter cloth clean, the cleaning nozzle will constantly clean the 

filter cloth, while it is soft impact to the floccules. the sludge concentration after thickening depends on solid

content of feeding sludge, dosing quanityt of flocc-ulation, rotating speed and dip angle of drum.

The advantage of rotary drum thickener

1.Fullly enclosed, no overflow of sludge,water,and gas.

2.Compact structure and small footprint.

3.Solid capture rate 95%.

4.High-performance,durable and no maintance basiclly.

5.Low energy consumption, low polymer consumption, low rotating speed.

6.Entirety body is made of stainless and high polymer matierial and structure.
