Micro-sand Recycling Shallow Air Flotation Water Treatment Equipment for Municipal Sewage Treatment
Product Overview
Our Micro-sand Recycling Shallow Air Flotation (SAF) System is a cutting-edge solution designed to revolutionize municipal sewage treatment. Combining micro-sand recycling technology with advanced shallow air flotation principles, this system delivers exceptional efficiency in removing suspended solids, oils, and contaminants. Ideal for cities and municipalities, it ensures compliance with strict environmental standards while minimizing operational costs and footprint.
Key Advantages
✅ Enhanced Efficiency with Micro-Sand Recycling
99.5% micro-sand recovery rate reduces material waste and operational expenses.
Accelerates flocculation and separation for >95% suspended solids removal.
✅ Precision Dosing & Automated Operation
Dry powder dosing system ensures accurate chemical mixing and uniform solution concentration.
Metering pumps automate chemical injection, reducing manual intervention and human error.
✅ Compact & Space-Saving Design
Shallow air flotation technology (effective depth <1m) cuts land use by 50% vs. traditional systems.
Modular construction simplifies installation in urban or space-constrained areas.
✅ Low-Cost & Energy-Efficient
Operational cost <¥0.1/ton | Energy-saving components reduce power consumption.
Durable materials (stainless steel, corrosion-resistant tanks) ensure long-term reliability.
✅ Stable & Clog-Free Performance
Vibration system prevents blockages in hoppers and pipelines.
Integrated controls maintain consistent effluent quality (turbidity <5 mg/L, TP <0.3 mg/L).
How It Works
Chemical Dosing: Powdered agents are fed from the hopper to the mixer, blended with water, and stored in solution tanks.
Micro-Sand Flocculation: Chemicals and micro-sand form dense flocs for rapid contaminant binding.
Shallow Air Flotation: Micro-bubbles lift flocs to the surface, where scum is scraped off.
Recycling: Micro-sand is recovered and reused, minimizing waste.
Applications
Municipal Sewage: Primary treatment, sludge thickening, and stormwater overflow management.
Industrial Pretreatment: Removal of oils, greases, and solids from wastewater.
Environmental Projects: Restoration of polluted rivers and lakes.
