Optimizing Sludge Dewatering with Lyure’s SDM353 Screw Press in Hunan

Project Overview

In 2013, Lyure Machinery partnered with a leading wastewater treatment facility in Hunan, China, to deploy a high-efficiency sludge dewatering system featuring two SDM353 Screw Presses. The contract, signed and installed in 2013, enabled the client to process 600 cubic meters of sludge per day. This advanced system streamlined sludge crushing, dewatering, and solid-liquid separation, significantly enhancing the client’s waste management efficiency and environmental compliance.

Client Needs

The Hunan-based client, a key player in municipal and industrial wastewater treatment, sought to modernize their sludge dewatering process to handle large volumes of sludge while meeting stringent environmental regulations. Their challenges included:

• High Moisture Content: Sludge required effective dewatering to reduce volume and facilitate cost-effective disposal or reuse.

• Operational Scalability: The need for a robust, integrated solution to manage crushing, dewatering, and solid-liquid separation in a high-capacity system.

• Environmental Standards: A requirement to process 600 m³ daily while adhering to Hunan’s strict environmental and wastewater treatment regulations.

Lyure’s Solution: SDM353 Screw Press

Lyure Machinery delivered a tailored solution with two SDM353 screw presses, designed specifically for high-capacity sludge dewatering:

• SDM353 Screw Press (Crushing and Dewatering): Each SDM353 unit integrates sludge crushing, high-pressure dewatering, and solid-liquid separation, achieving a moisture reduction rate of over 65% with its customizable mesh screen (0.4–2.0 mm). The dual-unit configuration ensures reliable throughput for processing municipal and industrial sludge, optimizing material recovery for disposal or further treatment.

• Integrated Functionality: The system supports sludge crushing, dewatering, and solid-liquid separation in a single, automated process, streamlining the waste management line.

• Processing Capacity: Handles 600 m³ per day, meeting the client’s high-volume processing requirements.

• Durability and Hygiene: Constructed from 304 stainless steel, the machines are corrosion-resistant, easy to clean, and compliant with industrial standards.

• Automation: The SDM353 units minimize manual intervention, reducing labor costs and ensuring consistent output.

Implementation

• Contract Signed: 2013

• Installation Completed: 2013

• Location: Hunan, China

• Material Processed: Sludge for dewatering

• Processing Capacity: 600 m³/day

• Machine Model: SDM353 (Crushing and Dewatering, 2 units)

Lyure’s technical team completed the installation in 2013, providing comprehensive on-site training to ensure seamless integration into the client’s wastewater treatment facility. The automated design of the SDM353 presses simplified operations and minimized downtime.

Results

Since its deployment in 2013, Lyure’s solution has delivered impressive results for the Hunan client:

• Effective Dewatering: Achieved a moisture reduction rate exceeding 65%, significantly reducing sludge volume and facilitating cost-effective disposal or reuse.

• Cost Efficiency: Automation and energy-efficient design cut operational costs by 20%.

• Environmental Compliance: The system ensured compliance with Hunan’s stringent wastewater treatment regulations, supporting sustainable waste management practices.

• Reliable Production: The dual-unit system consistently processed 600 m³ daily, meeting the client’s operational demands.
