Large stainless steel high-efficiency screw press sludge dewatering machine is an advanced equipment designed for efficient sludge treatment. Made of high-quality stainless steel, it is durable and corrosion-resistant, ensuring long-term stable operation. The unique screw pressing structure can efficiently squeeze out the water in the sludge through step-by-step pressurization, achieve rapid dehydration, greatly reduce the sludge moisture content, and the dehydration effect is significantly better than traditional equipment. The equipment runs smoothly, has low energy consumption, and has a strong processing capacity, which can meet the needs of large-scale sludge treatment. At the same time, it has a high degree of automation, is easy to operate, and has low maintenance costs. It is suitable for municipal sewage treatment plants, industrial wastewater treatment and other fields.
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 Large Stainless Steel High-Efficiency Screw Press Sludge Dewatering Machine is engineered for effective and continuous dewatering of industrial and municipal sludge. By utilizing a unique combination of a screw press and a multi-disk filter, this system achieves superior solid-liquid separation while minimizing energy consumption and operational footprint. It is designed to meet the rigorous demands of various applications, including wastewater treatment plants, food processing, and chemical manufacturing, where efficient sludge volume reduction is critical.
This sludge dewatering equipment is widely used in industries requiring efficient solid-liquid separation:
A screw press typically has a lower operational cost due to its low energy consumption and minimal need for high-pressure wash water. Unlike a centrifuge, it doesn't require high rotational speeds or a large power supply, and it avoids the continuous consumption of filter cloth seen with belt presses. Maintenance is also simplified as there are fewer moving parts and no complex filter media to replace. The system's self-cleaning rings and low-speed operation contribute to its long-term reliability and cost-effectiveness. The best choice depends on your specific sludge characteristics, required dryness, and flow rate. Our technical team can provide a detailed comparison based on a free analysis of your specific operational data.
For optimal performance and efficient dewatering, sludge typically requires proper flocculation. The addition of a polymer or other flocculant agent is necessary to aggregate the fine solid particles into larger flocs. This process is crucial for improving the dewaterability of the sludge, allowing the screw press to achieve a higher solids content in the cake. Our machine is often integrated into a complete sludge treatment line that includes a polymer dosing system. The specific type and dosage of the flocculant must be optimized for your particular sludge composition. We offer consultation services to help you determine the most effective pretreatment strategy for your application.
