Product Description
 

High Efficiency Screw Press sludge dewatering machine Filter Equipment for Wastewater Treatment Plant Press Filter Equipment

 Introduction:
The stacked screw type sludge dewatering machine is suitable for solid-liquid separation of materials in industries such as sewage treatment plants, food, pharmaceutical, chemical, petrochemical, papermaking, metallurgy, printing and dyeing, livestock and poultry, etc. It is often used to further dehydrate concentrated sludge (with a moisture content of 95-97%) or low concentration sludge (with a moisture content of 99.7% -97%) into sludge cakes (with a moisture content of 30-85%) during sewage treatment.

The Screw press Sludge Dewatering Press can be provided with all equipment required for dewatering included and factory mounted, piped and wired on a single stainless steel skid. This equipment includes the sludge pump, wash water pump, polymer dosing system and control panel. The system features fully automated one pushbutton startup and shutdown. Once started up the system can run unattended and can be set to shutdown automatically with no operator intervention.

 

 

Main Features

1. Automatic continuous operation

2. Compact design with flocculation and dewatering

3. Low power and water consumption

4. Low operation cost

5. No filter cloth, no clogging

6. Easy operation and maintenance

When the machine starts running,the sludge is pumped into the screw press from the feed inlet port ,then enters into the flocculation mixing tank,and then gradually goes through screw shaft main body,and at last discharged from the sludge cake outlet port.Because the gaps between the screw shaft blades will gradually getting narrower,the sludge is bearing heavier pressure.Then the water is gradually dehydrated.Relying on the self-cleaning function of the fixed plates and the moving plates,block issue can be well avoided .

Sludge Overflow: Sludge is pumped into the dehydrator inlet tank, and from there, it flows over a triangular overflow discharge into the flocculation tank. Sludge quantities exceeding the equipment capacity, are returned through the safety overflow.
 
Flocculation: The flocculation tank is stirred with a low-speed paddle mixer, and the polymeric flocculent is dosed into the incoming sludge. The flocculent solution is prepared directly at the wastewater treatment plant, by mixing the concentrated reagent with water, in an independent tank. It is then dosed in sufficient quantities by a dosing pump. The reaction of the flocculent with the sludge, causes clearly defined flakes to be formed in the dehydrator flocculation tank and subsequently brought into the thickening and dewatering drum.
 
Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank by gravity.
 
Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produced.
Self-cleaning: The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering equipment.
