Core Advantages - Why Choose Our Screw Press?
✅ Ultimate Energy Efficiency & Cost Savings
Low-speed operation with main motor power of just 1.5-3kW, reducing energy consumption by 60% compared to traditional dewatering equipment
No high-pressure water pump flushing required, saving tens of tons of water daily
✅ High Sludge Solids Content
Multi-stage variable-diameter screw shafts and back-pressure plate design ensure steadily increasing pressure
Sludge cake moisture content consistently maintained at 75%-80% (depending on sludge properties), facilitating transportation and resource recovery
✅ Fully Automated Unattended Operation
Integrated PLC intelligent control system supports one-touch start/stop, real-time status monitoring, and fault alerts
Optional GPRS remote monitoring for seamless IoT platform integration
✅ Ultra-low maintenance costs
Core screw shafts utilize wear-resistant alloy + laser cladding technology for 2x extended lifespan
Open structure allows quick filter screen removal and cleaning, eliminating clogging risks
✅ 50% space savings
Modular compact design eliminates need for bulky auxiliary systems, ensuring flexible and convenient installation
Application Industries and Scenarios
Our screw presses provide ideal solutions for the following sectors:
Municipal wastewater treatment plants: Efficient processing of waste activated sludge (WAS) and digested sludge
Food processing industry: Treatment of slaughterhouse wastewater, fruit and vegetable processing sludge, starch residue, and brewery sludge
Chemical and pharmaceutical industries: Processing of organic chemical sludge and fermentation mycelium
Paper and pulp industry: Treatment of pulp fiber residues
Shipboard wastewater treatment: Compact design perfectly suited for onboard space constraints
Four Core Pain Points We Solve for Customers
High disposal costs: Significant sludge reduction directly lowers transportation and landfill/incineration expenses.
Massive energy and water consumption: No flushing pumps required, extremely low power consumption, with overall operating costs 50% lower than belt machines.
Complex operation and management: Fully automated operation requires no dedicated personnel, reducing labor costs.
Limited site space: Highly integrated equipment occupies only 2-5 square meters.
