TPDL Volute screw press sludge dewatering System

-With sludge transfer pump. auto-dosing equipment and shaftless auto screw conveyor

for wastewater treatment plant, sewage treatment plant, effluent treatment plant, sludge treatment plant, waste management.

Features:

1,Widely Use

1)Can be widely used in municipal sewage, food, slaughtering breeding, printing and dyeing, oil chemical industry, paper making, leather, pharmaceutical and other industries of sludge dewatering;

2)Exclusive pre-concentration design, applicable sludge concentration of 2000mg/L-50000mg/L;

3)Due to the innovation of the structure design, it is highly suitable to various high and low concentration sludge, most especially for the oily ones.

2,Clog-free Due to rotation of helical axis, the moving rings begin detaching from the fixed rings while continuously starting the self-cleaning process. As a result, the ubiquitous clogging is avoided. Therefore, it can handle oily sludge without any trouble while separating the water from the sludge easily. In addition, there is no need to add large quantity of flushing water and there is no odor and no secondary pollution during the dewatering process.

3,Fully Automatic Control There are no easily blocked pieces such as belt and filtration pore in Multi-Disk Screw Press. Combining with the auto control system, the machine runs very safely and simply and can be programmed according to the requirement of the users. It can operate automatically for 24 hours, unmanned.

4, No secondary pollution The screw shaft rotational speed about 2~3r/min, no vibration and noise is very small ; The laminated with self - cleaning function, plugging does not occur, only a small amount of water washing, without secondary pollution, and sludge at such a slow running under the operating condition, the smell does not spread, thereby creating a great work environment!

5,Promote the phosphorus removal capability Dewatering sludge under aerobic conditions, it does not occur phosphorus release, so as to enhance phosphorus removal function of the whole sewage treatment system.

6,Suitab for Oily Sludge The self-cleaning mechanism and stainless steel structure enables DL to be ideal to dewater oily sludge.

7,Save Running Cost Multi~Disk Screw Press works by the machine's internal pressure and needs no large scale integrations like rollers. It saves energy and water and has very minimal noise because of low running speed (2-4 r/min). The average unit power consumption is only 0.1-0.01kwh/kg-DS (1/8 of Belt Press and 1/20 of Centrifuge), and can greatly reduce the running cost of wastewater treatment system.

8, Lightweight and durable Due to the direct mechanical dewatering extrusion without rollers and other large body, so the machine is in lightweight; the body almost entirely made of stainless steel, replacement parts are only screw shaft and moving rings, it is durable with long service time.

9,Decrease Project Investment Multi~Disk Screw Press can treat sludge in aeration tank and secondary sedimentation tank without setting sludge thickeners. Therefore, this can decrease the total investment, avoid phosphorus release from the sludge thickeners and sludge storage tanks and enhance phosphorus removal effect of the wastewater treatment system.

Advantages:

1) Not clog: Self-cleaning structure, Processing the fats & oil and fiber sludge perfectly.

2) Full automatic control: Combining with the auto control system, the machine can operate 24 hours unmanned.

3) Saving Running cost: Water-saving, Power-saving, Drugs-saving etc. ex:power cost only 1/8 of the belt, the water cost less than 0.1% of the belt.

4) No secondary pollution: The screw shaft rotational speed is 2-4 r/min, so there is no noise, vibration and smell.

5) Lightweight and durable: Mechanical dewatering extrusion without rollers and other large body. Stainless steel ensure long service time.

6) Decrease project investment: Integrating with auto-control cabinet, sludge thickening & dewatering body liquid collection tank

Screw Press VS Belt Press, Centrifuge, Plate-and-frame Filter Press

Application:

1) Municipal water and wastewater treatment plants

2) Agricultural/fishery community wastewater treatment plants

3) Industrial waste treatment plants

4) Food/beverage production plants

5) Dairy farming/Meat processing plants, Slaughter house

6) Chemicals manufacturing plants

7) Machinery manufacturing/Metal processing plants

8) Laundry wastewater

9) pulp and paper mills, Dyeing and Printing, oilfield associated water accompanied with crude oil mining, etc.)

Working principle:

The wastewater is pushed into the dewatering machine.The sludge will move to the sludge cake outlet under the pressure of the helical aixs blades. Becuse the gap among the helical blades become narrower,so the sludge bear heavier pressure and began to dewatering under the pressure. The water comes out from the space between fixed and moving plates.
