Key Advantages of AquaSust Small Capacity Sludge Dewatering Machine
AquaSust small capacity sludge dewatering machines combine compact equipment design with continuous screw press dewatering for wastewater treatment projects with relatively low sludge loads.
Compact Equipment Footprint
The small-capacity series uses compact machine configurations to help reduce the space required for sludge dewatering equipment. This makes it easier to arrange the dewatering unit in treatment plants with limited available floor space.
01
Simplified Equipment Installation
Sludge conveying, thickening, dewatering, and cake discharge are integrated into one screw press system. The integrated configuration helps simplify equipment arrangement and connection within smaller wastewater treatment systems.
02
Suitable for Lower Sludge Loads
The small-capacity range covers approximately 6–30 kg DS/h and includes AS-NH-131, AS-NH-132, AS-NH-201, and AS-NH-202. Multiple models provide different processing capacities for projects with relatively low sludge production.
03
Accessible Routine Maintenance
The concentrated equipment structure provides practical access to the main operating components for routine inspection, cleaning, and maintenance. This helps smaller treatment facilities organize regular equipment servicing without complex maintenance arrangements.
04
Integrated Screw Press Components
The machine incorporates a screw shaft with a cobalt alloy wear layer, SS304 spray pipe and nozzles, a stainless steel protective cover with PMMA viewing windows, and a Schneider Electric control cabinet. These components support sludge conveying, internal cleaning, equipment protection, process observation, and electrical control.
05
Germany Schneider Electric Control Cabinet
AquaSust small capacity sludge dewatering machines are suited to wastewater treatment facilities with relatively low sludge production and limited equipment space, supporting decentralized and small-scale sludge dewatering requirements.

Food Processing Wastewater Treatment
AquaSust provides small, medium, and high capacity sludge dewatering machines to cover different sludge loads and treatment requirements, with multiple models available for different wastewater treatment conditions and processing capacities.
AquaSust Quality Control Throughout the Production Process
AquaSust maintains quality control throughout production to ensure each sludge dewatering machine meets the specified manufacturing and assembly requirements.
- Raw Material Verification - Incoming stainless steel and other major materials are checked against specified material grades, dimensions, surface condition, and supplier documentation before fabrication.
- Component & Dimensional Inspection - Key components such as the screw shaft, dewatering sections, spray system, covers, frames, and connection points are checked for dimensions, fit, and visible manufacturing defects.
- Welding & Fabrication Inspection - Welded structures and stainless steel components are inspected for weld appearance, continuity, deformation, and fabrication defects.
- Mechanical Assembly Inspection - The screw shaft, drive system, dewatering assembly, spray components, and other connected parts are inspected during assembly to verify alignment, fastening, clearance, and mechanical operation.
- Electrical & Control System Inspection - Motors, control cabinets, electrical connections, sensors, and operating controls are checked during assembly to verify correct connection and functional response.
- Finished Machine Inspection - Each completed sludge dewatering machine undergoes a final inspection covering overall dimensions, appearance, component installation, protective covers, connections, and operating condition before packaging and delivery.

FAQ
Q: How do I choose the right model from the small capacity range?
A: Model selection should be based on the required dry solids capacity, sludge concentration, and actual sludge characteristics. AquaSust provides four models, from approximately 6 to 30 kg DS/h, allowing buyers to match the machine to different sludge loads.
Q: Does the listed treatment capacity apply to all sludge conditions?
A: No. The actual sludge treatment volume varies with sludge concentration and the flocculation effect of sludge and chemicals. The listed processing volumes are theoretical reference values and should be evaluated together with the actual sludge conditions.
Q: What information should I provide for model selection?
A: Buyers should provide available information such as sludge type, sludge concentration, expected sludge production, and required treatment capacity. These parameters help AquaSust determine a suitable machine configuration for the application.
Q: Can the machine be used for different wastewater treatment applications?
A: Yes. The small capacity range is intended for relatively low sludge loads and is used in applications including decentralized, municipal, commercial, industrial, food processing, livestock, and residential wastewater treatment systems.
Q: What should I consider when planning the equipment space?
A: Buyers should consider the selected model's mechanical dimensions, operating weight, surrounding maintenance space, and the space required for sludge feeding, cake discharge, cleaning, and related connections during layout planning.
Q: What is covered by the sludge dewatering machine warranty?
A: AquaSust provides a 1-year warranty for sludge dewatering machines. Quality-related problems covered by the warranty are handled according to the company's warranty policy, while exclusions include misuse, unauthorized repair or modification, improper maintenance, and normal wear and tear.
