Hassle-Free Multi-Plate Screw Press for Sewage Dewatering
Description
The multi-plate volute screw sludge dewatering system uses mechanical screw press principles to separate solids from liquids. The main structure consists of multiple fixed rings and movable rings with a screw shaft running through them. The front section concentrates the sludge, while the rear section applies pressure to remove water. This two-step process occurs within a single enclosure, eliminating the need for separate thickening and dewatering equipment.
Core Features of BOEEP Sludge Dewatering Systems
Multi-Plate Separation Technology
Each unit features 12 laser-cut 304 stainless steel plates (0.8mm thickness) creating a 1.2m² filtration surface, which captures particles 20μm and larger. The helical screw (100mm pitch) rotates at 15 RPM, applying gentle mechanical pressure to squeeze water through plate gaps without damaging floc structure. Plate spacing is adjustable from 2-5mm via a handwheel, allowing optimization for different sludge types in under 2 minutes.
Automated Operation and Low Maintenance
An automatic torque control system detects excess solids buildup and reverses screw rotation for 10 seconds, preventing motor burnout and eliminating manual unclogging. The design includes only two wearable parts: screw bearings and nozzle filters, with replacement intervals of 12+ months under normal operating conditions. The compact footprint measures 2m (L) × 1m (W) × 1.5m (H), fitting into tight spaces in retrofitted facilities.
Energy-Efficient Performance
The 2.2kW IE5 super-premium efficiency motor uses 50% less electricity than traditional belt presses, resulting in annual savings of $3,000+ in medium-sized facilities. An internal flushing system recycles clarified water from the plant's effluent tank, consuming only 0.3m³/h of water.
Applications Across Industries
These dewatering systems serve municipal and industrial clients across multiple sectors. They handle primary sludge (3-5% solids) and secondary sludge (0.5-1% solids) from municipal sewage treatment plants with equal efficiency. For industrial applications, they process food processing sludge (low fiber), textile dye sludge (organic matter), and small-scale manufacturing waste (non-abrasive solids). The systems are also suitable for decentralized plants serving populations under 50,000, with proven performance in over 50 small-scale systems.

FAQ
What is the typical payback period for these systems?
For facilities processing 50m³/day, the typical payback period is under 18 months. This is achieved through 60% reduction in labor costs and 40% reduction in energy bills.
How much training is required for operators?
The intuitive HMI panel with 4-button control allows operators to start/stop the system and adjust settings after a 30-minute training session. No dedicated operator is required for normal operation.
What types of sludge can be processed?
The systems can process primary sludge, secondary sludge, tertiary sludge, anaerobic digested sludge, and aerobic sludge. They are also effective for industrial sludges from food processing, textile, pharmaceutical, and paper making industries.
What is the uptime record for these machines?
Tested in over 100 sewage plants worldwide, including Washington, DC's Blue Plains Advanced Wastewater Treatment Plant, these systems have a 98% uptime record over 5 years.
