The fully automatic livestock wastewater treatment screw press sludge dewatering machine is an efficient and environmentally friendly livestock farm wastewater treatment machine. The compact system separates solid and liquid waste through a rotating screw mechanism, which can reduce the amount of sludge by up to 80%, while recovering reusable water. The automated operation requires almost no human intervention, and is equipped with a self-cleaning filter and adjustable pressure settings to handle different waste concentrations. The dewatered sludge (65-75% dryness) can be used as organic fertilizer, and the filtered water can meet discharge standards or be recycled. The equipment has low energy consumption, corrosion-resistant materials and good odor control capabilities.
The main body of the spiral screw machine is composed of stationary rings and movable rings stacked into a cylindrical shape, with a spiral shaft running through it to form a filtering device. Because the inner diameter of the movable ring is smaller than the outer diameter of the spiral shaft, the rotation of the spiral shaft can drive the movable ring to perform circular motion, preventing blockages. The gap between the stationary ring and the movable ring gradually narrows along the direction of the mud cake outlet, from the thickening to the dewatering section. After the sludge is thickened by gravity in the thickening section, it is gradually transported to the dewatering section, where forced dewatering is achieved under the internal pressure generated by the back pressure plate at the discharge outlet.
Advantages of the spiral screw:
1. Proficient in handling oily sludge: Compared to traditional sludge dewatering machines, the self-cleaning structure of the spiral screw is less likely to cause filter gap blockages, and it can easily handle oily sludge.
2. Compact design, space-saving: Compared to traditional sludge dewatering machines, the dewatering body, flocculation mixing tank, and electrical control cabinet of the spiral screw sludge dewatering machine adopts a three-in-one design, which is convenient for installation, occupies a small volume, and is highly compatible with ancillary supporting equipment, facilitating the replacement of existing equipment.
3. Simple operation and maintenance: It can be fully automatic and unattended for 24 hours through various sensing devices, and at the same time, there are few daily maintenance items, and maintenance work is simple.
4. Energy-saving: As the core component of the spiral screw, the rotation speed of the spiral shaft is 0-5 revolutions per minute. Due to the low-speed rotation, the electricity consumption is deficient. Under the same treatment capacity, the electricity consumption of the spiral screw is only 1/20 of that of the centrifugal dewatering machine.
5. Water-saving: The self-cleaning structure of the spiral screw body that prevents filter gap blockage can save a large amount of water for cleaning. Under the same treatment capacity, the water consumption of the spiral screw is only 1/115 of that of the belt dewatering machine.
6. Wide application range: Suitable for various industries such as municipal, tap water, pharmaceuticals, food, beverages, animal husbandry, chemical, machinery manufacturing, metal processing, petrochemical, and printing and dyeing.
7. Low noise, low vibration: The spiral shaft of the spiral screw body rotates at low speed, with almost no noise and vibration, ensuring a comfortable and quiet working environment.

The Fully Automatic Livestock Wastewater Treatment Screw Press Sludge Dewatering Machine is an engineered solution designed for the efficient separation of solids from liquid in animal waste streams. Utilizing a specialized screw press dewatering mechanism, this equipment effectively reduces the volume of livestock wastewater, producing dry cake suitable for subsequent processing while recovering liquid for reuse or safe discharge. This system is crucial for farms and agricultural operations seeking to comply with environmental regulations and improve waste management efficiency.
This product is an ideal solution for:
The screw press stands out for its low energy consumption and simple, continuous operation. Unlike a centrifuge, it does not require a high-power motor and can handle a wider range of sludge concentrations without performance drops. Compared to a belt filter press, the screw press is more compact, requires less footprint, and its self-cleaning mechanism prevents clogging, which is a common issue with fibrous livestock waste. The low operating cost and ease of maintenance make the screw press a superior choice for farm wastewater dewatering. For a detailed comparison based on your specific waste stream, our technical specialists are available for a complimentary process analysis.
Our screw press features a robust design with a service life of the main components (screw and rings) exceeding 5 years under normal operating conditions. The unique design of the fixed and movable rings, combined with the slow rotational speed of the screw, creates a continuous self-cleaning action that prevents material buildup and jamming. The gap between the rings narrows along the screw's length, progressively squeezing out water while allowing solid particles to be conveyed forward. This design is highly effective at managing fibrous waste from animal manure treatment. Regular maintenance and proper polymer dosing are key to ensuring long-term, trouble-free operation.
