Livestock Wastewater Treatment Screw Press Sludge Dewatering Machine QXDL-403

The Screw Press Sludge Dewaterer for Livestock Wastewater Treatment is an efficient and compact solution for dewatering livestock wastewater sludge. The machine uses a rotating screw mechanism to continuously apply pressure to separate the sludge from the liquid, reducing the sludge volume by up to 80%. The machine is designed for high-capacity processing and can handle various types of sludge with low energy consumption and low maintenance costs. The machine is equipped with a self-cleaning screen to prevent clogging and ensure stable operation. Used on farms and biogas plants, it can produce a drier filter cake that is easier to handle or use as fertilizer.

QXDL-403 Screw Press Sludge Dewatering Machine
◈

The QXDL-403 Screw Press Sludge Dewatering Machine is a high-performance industrial dewatering system specifically engineered for livestock wastewater treatment applications. Utilizing a progressive screw pressing mechanism, the machine continuously dewaters sludge from livestock operations including pig farms, cattle ranches, and poultry facilities. The screw press design features a rotating screw shaft with increasing compression ratios, forcing sludge through a cylindrical screen that separates liquid from solid material. The resulting dewatered cake has a dry solids content of 25-35%, significantly reducing disposal volume and associated hauling costs. The machine's robust construction with stainless steel contact parts ensures corrosion resistance and long service life in demanding agricultural environments. With a dry sludge treatment capacity of 240-480 kg/h and low power consumption of 7.5 kW, the QXDL-403 offers an energy-efficient solution for livestock producers seeking sustainable waste management practices.

Operating and maintenance notes
Inlet sludge preparation Inlet sludge should have 0.5-5% solids content for optimal performance. Avoid fibrous or abrasive materials that may damage the screw mechanism.
Flocculant addition Polymer flocculant recommended for enhanced dewatering. Dosage 2-5 kg/ton dry solids depending on sludge characteristics.
Scheduled maintenance Inspect screw shaft and screen monthly. Replace worn components per schedule. Lubricate bearings every 500 operating hours.
Cleaning procedure Wash down machine after each shift. Use high-pressure water spray. Do not use acidic or chlorinated cleaning agents.
Frequently asked questions
◈ What dry solids content can the QXDL-403 achieve?
The QXDL-403 produces dewatered sludge cake with a dry solids content of 25-35% depending on sludge type and flocculant addition. For pig and cattle manure, typical results are 28-32% dry solids. The screw press design with adjustable compression ratio allows operators to optimize output based on application requirements.
◈ How does the QXDL-403 compare to centrifuge or belt press dewatering?
The screw press offers lower energy consumption (7.5 kW) compared to centrifuges (typically 30-50 kW) and belt presses (15-25 kW). It also provides continuous, quiet operation with less maintenance. The screw press is particularly effective for livestock wastewater where sludge has high organic content and fibrous material that can clog other systems. The initial investment is typically lower than centrifuges with comparable capacity.
◈ What is the recommended flocculant type and dosage?
High-molecular-weight cationic polyacrylamide flocculant is recommended for livestock wastewater sludge. Dosage typically ranges from 2-5 kg per ton of dry solids. Flocculant selection and dosage should be determined through jar testing with actual sludge samples. Jiangsu Aozheng Metal Products Co., Ltd. provides flocculant optimization support for each installation.
◈ What maintenance is required for the QXDL-403?
Regular maintenance includes monthly inspection of the screw shaft and screen for wear, bearing lubrication every 500 operating hours, and daily washdown after use. The screen should be replaced every 2-3 years depending on operating hours and sludge characteristics. Spare parts including screen segments and screw flight are available from Jiangsu Aozheng Metal Products Co., Ltd. The company provides maintenance contracts and operator training for all installations.
