Screw Sludge Thickener can concentrate sludge rapidly and continuously from the secondary sedimentation tank. After condensed and separated, the sludge concentration can be adjusted between 90% and 96% stably. There are many advantages after make use of this device, such as no need concentrated tank, small footprint, less cost, effectively reduce the odor & phosphprus release caused by sludge concentrated tank, easy the following treatment process, greatly improve, greatly inprove the process capacity of sludge dewatering and deep dehydration equipment.
Screw Sludge Thickener mainly consists of condensed body, drive mechanism, filtrate tank, mixing system, frame etc.
During operating, the sludge is conveyed to the mixing tank by sludge feeding pump, meanwhile, polymer feeding pump feeds polymer liquid to the mixing tank quantitatively.
The sludge is mixed completely with the polymer liquid under the drive of mixing system, thus , the flocs appear.
When the liquid reaches the sensor level of liquid sensor, the screw body will get into operation, and the sludge is being pressed into the screw body .
Then,the sludge will being lifted to sludge outlet port step by step under the drive of screw shaft, the filtrate will come out between the fixed annular plate and moveable annular plate clearance at the same time.
Generally speaking, Screw Sludge Thickener makes use of screw extrusion principle, it is a new solid and liquid separator with strong extrusion pressure generated by the distance change of screw diameter pitch, and small gap between and swimming ring and the fixed ring.
Large sludge concentration range,
Applied water content of sludge:98%～99.8%
The concentrated water content of sludge is 90%～96%
which can be adjusted stably
High concentration efficiency, Small footprint
No need filter cloth, Self-cleaning,Clog free, No high pressure back wash water
Low Rotating Speed, Low noise, Low Power Consumption, Compact Design,
Completed Enclosure, Little Odor
Less wearing parts, Easy to operate & Maintain
Fully-automatic Control. Low Labor Need
