Product Specification

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

1. Chemical Dosing: Powdered agents are fed from the hopper to the mixer, blended with water, and stored in solution tanks.

2. Micro-Sand Flocculation: Chemicals and micro-sand form dense flocs for rapid contaminant binding.

3. Shallow Air Flotation: Micro-bubbles lift flocs to the surface, where scum is scraped off.

4. 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.

Project Case

Inner Mongolia Ordos Mine Water Fluoride Removal System Renovation Project The construction of the project has the following characteristics: 1. The construction period of the project is short: dismantle the original equipment, install new equipment and commission, a total of one week. 2. Small footprint: dismantle the original hydroxyapatite filter and sedimentation tank and replace it with a special fluoride removal air flotation tank, reducing the floor area by one-third. 3. Stable effluent: The effluent of the equipment is stable and up to standard, and the effluent is less affected by the fluctuation of inlet water quality, which changes the problem that the effluent of the filter is easy to exceed the standard. 4. Low O&M costs: O&M costs are low and controllable.
