Modern wastewater treatment requires advanced technologies to ensure efficient solid-liquid separation, precise chemical dosing, and effective sludge dewatering. Three key innovations—Hydraulic Screen Solid-Liquid Separator, PMA-Integrated Frequency-Converting Dosing Device, and Screw Press Sludge Dewatering Machine—play pivotal roles in optimizing these processes.

1. Hydraulic Screen Solid-Liquid Separator
The Hydraulic Screen Solid-Liquid Separator is a high-efficiency filtration system designed to remove suspended solids from wastewater. It operates using hydraulic pressure to force liquid through a fine screen while retaining solids for disposal or further processing.
Key Features:
High Separation Efficiency: Removes up to 95-98% of suspended solids (depending on screen mesh size).
Low Energy Consumption: Uses hydraulic pressure instead of mechanical force, reducing power usage by 20-30% compared to traditional filters.
Self-Cleaning Mechanism: Minimizes clogging and maintenance downtime.
Wide Application: Suitable for municipal wastewater, industrial effluents, and agricultural runoff.
Performance Comparison
| Parameter | Hydraulic Screen Separator | Traditional Drum Screen |
|---|---|---|
| Separation Efficiency | 95-98% | 85-90% |
| Energy Consumption | Low (20-30% less) | Higher |
| Maintenance Frequency | Minimal (self-cleaning) | Frequent manual cleaning |
2. PMA-Integrated Frequency-Converting Dosing Device
Precision in chemical dosing is critical for wastewater treatment. The PMA-Integrated Frequency-Converting Dosing Device ensures accurate and automated chemical injection, optimizing flocculation and disinfection processes.
Key Features:
Automated Control: Adjusts dosing rates in real-time based on flow and contaminant levels.
Energy Savings: Frequency conversion reduces power consumption by 15-25%.
High Accuracy: Dosing precision of ±1%, minimizing chemical waste.
Compatibility: Works with coagulants, polymers, and pH-adjusting chemicals.
Performance Comparison
| Parameter | PMA Dosing Device | Conventional Dosing Pump |
|---|---|---|
| Dosing Accuracy | ±1% | ±5% |
| Energy Efficiency | 15-25% savings | Standard consumption |
| Automation Level | Fully automated | Manual adjustments needed |
3. Screw Press Sludge Dewatering Machine
After solid-liquid separation, sludge requires further dewatering to reduce volume and disposal costs. The Screw Press Sludge Dewatering Machine offers a continuous, low-energy solution for sludge thickening.
Key Features:
High Dewatering Efficiency: Achieves 75-85% dryness, reducing sludge volume by 60-70%.
Low Operational Cost: Consumes 30-40% less energy than centrifugal dewaterers.
Compact Design: Requires less space compared to belt filter presses.
Low Noise & Vibration: Ideal for urban wastewater plants.
Performance Comparison
| Parameter | Screw Press Dewatering | Centrifuge Dewatering | Belt Filter Press |
|---|---|---|---|
| Dryness Achieved | 75-85% | 70-80% | 65-75% |
| Energy Consumption | Low | High | Moderate |
| Maintenance Needs | Minimal | High (bearing wear) | Moderate (belt replacement) |
