High-Efficiency Water Treatment Equipment for Municipal Sewage Plant Micro Sand Loading and Multi Effect Clarification Product Overview
The WPG Combined Dissolved Air Flotation System is an advanced water treatment solution that integrates dissolved air flotation (DAF) with enhanced flocculation and high-efficiency sedimentation. By introducing micron-level quartz sand as a carrier, the system strengthens the flocculation process, accelerates sedimentation, and significantly improves contaminant removal efficiency.
With a compact and highly integrated design, this system is ideal for municipal sewage plants, overflow pollution control, and water plant pre-treatment. It ensures high removal rates for suspended solids (SS), total phosphorus (TP), and chemical oxygen demand (COD), while maintaining stable and clean effluent quality.
How It Works
Dosing and Coagulation
Coagulants and flocculants are added to the raw water, forming flocs.
Micro-Sand Enhanced Flocculation
Micron-level quartz sand acts as a carrier, strengthening the floc structure and increasing the sedimentation rate.
Efficient Sedimentation
The sedimentation section achieves a surface load of 40–65 m³/m²·h with a total residence time of less than 20 minutes.
Mud-Sand Separation and Recycling
The integrated system efficiently separates sludge and recycles micro sand for continuous use, improving operational efficiency and reducing waste.
Dissolved Air Flotation (DAF)
Microbubbles attach to flocs, increasing their buoyancy and accelerating the separation of suspended particles and contaminants from water.
Key Features
