Key Features & Advantages
1. Space-Saving Vertical & Compact Design
Featuring an innovative vertical screw press layout, this dehydrator occupies a remarkably small floor area compared to traditional horizontal models. Its compact design screw dehydrator is engineered for easy integration into existing treatment lines, retrofit projects, or facilities with severe space constraints, maximizing plant layout efficiency without compromising capacity.
2. Robust Stainless-Steel Construction
All wetted and structural components are constructed from high-grade stainless steel (304/316), providing exceptional resistance to corrosion, abrasion, and the harsh chemical environment of various sludges. This ensures long-term durability, hygiene, and minimal maintenance, safeguarding your investment over years of continuous operation.
3. High-Efficiency Screw Press Dewatering
At its core is a powerful, continuously operating screw press mechanism. The screw applies increasing mechanical pressure as it conveys sludge upwards, efficiently separating water from solids to achieve a high dryness sludge cake. This process ensures maximum volume reduction, lowering subsequent disposal or transportation costs.
4. Fully Automatic & Intelligent Control
The system is managed by a programmable logic controller (PLC) for fully automatic operation. It intelligently adjusts screw speed and back pressure based on real-time feed conditions. This automatic screw press control enables stable, hands-free dewatering, optimizes polymer dosage, and minimizes operator intervention.
5. Energy-Efficient & Low Operational Cost
The vertical design and efficient drive system result in significantly lower energy consumption compared to many centrifugal dewaterers. Combined with low polymer demand and minimal maintenance needs, it offers a truly low operational cost dewatering solution.
6. Versatile Sludge Handling Capability
This vertical screw dehydrator is highly effective on a wide range of materials, including municipal biological sludge, industrial chemical sludge, food processing waste, and livestock manure. Its adjustable parameters allow it to be fine-tuned for optimal performance with different feedstocks.
Application Scenarios
1. Municipal Wastewater Treatment Plants
Ideal for dewatering excess activated sludge or digested sludge in small to medium-sized WWTPs, package plants, or satellite treatment facilities, reducing sludge volume for cost-effective disposal.
2. Industrial Wastewater Treatment
Suitable for dewatering chemical sludges from industries such as pharmaceuticals, textiles, paper & pulp, and metal processing, helping to meet strict discharge or recovery standards.
3. Food & Beverage Processing Plants
Effectively handles organic sludges and processing waste from food production, reducing weight and volume for off-site disposal or facilitating further composting/biogas production.
4. Agricultural & Livestock Operations
Used to dewater manure slurry, making it easier to handle, transport, and utilize as fertilizer, while improving farm environmental management.
Operation & Maintenance Guide
Operation is streamlined for ease: after connecting the feed sludge, polymer, and power lines, the desired program is selected on the touchscreen. The system then runs automatically, including start-up, conditioning, dewatering, and shut-down/cleaning cycles. Daily tasks are minimal, primarily involving visual inspection and ensuring hoppers are clear. Routine maintenance includes periodic inspection of the screw flights and screen, lubrication of bearings, and cleaning of spray nozzles. Detailed manuals are provided.
