Innovative and Highly Integrated Shallow Air Flotation Water Treatment Equipment for Industrial Wastewater

Product Overview

The ShallowAirFloat™ is a revolutionary shallow air flotation (SAF) system designed for rapid, high-efficiency removal of oils, heavy metals, algae, and suspended solids from industrial wastewater. Combining the "Shallow Pool Theory" and "Zero Velocity Principle", this compact, fully integrated solution delivers unmatched performance in turbidity reduction, sludge thickening, and pollutant separation—ideal for industries demanding space-saving, low-cost, and eco-friendly water treatment.

Core Technology

• Micro-Nano Bubble Fusion: Generates ultra-fine bubbles (5–10μm) for superior adhesion to contaminants, achieving >98% suspended solids removal.

• Zero-Velocity Dynamic: Inlet/outlet zones remain static, minimizing flow disturbance for instant scum removal and stable effluent quality.

• High-Speed Sedimentation: Shallow tank depth (730mm) + 3–5 min retention time = 50% faster treatment vs. traditional systems.

• Self-Cleaning Design: Non-clogging dissolved air release mechanism ensures 99.5% micro-sand recovery with zero secondary pollution.

• Smart Integration: Fully automated controls (PLC/HMI) for seamless operation and minimal maintenance.

Why Shallow Air Float?

✅ Space-Saving: 70% smaller footprint than conventional flotation tanks.
✅ Cost-Efficient: <¥0.1 per ton operational cost with ultra-low power consumption.
✅ Versatile Performance: Handles oils, heavy metals (e.g., electroplating), algae, paper pulp, tannery waste, and more.
✅ Rugged & Reliable: Corrosion-resistant materials withstand harsh industrial environments.

Key Applications

• Oil Refining & Machining: Rapid oil-water separation for coolants and refinery wastewater.

• Textile & Printing: Effective color/impurity removal from dyeing wastewater.

• Paper/Pulp Mills: White water recycling with 98% clarity recovery.

• Municipal & Rural Sewage: Pretreatment and sludge thickening (e.g., Lishui MABR Project).

• Marine & Desalination: Seawater pre-treatment for algae/particulate removal.

Project Case

Lishui Agricultural Pollution MABR Project Project process introduction The rural domestic sewage treatment in Shenyang Village, Jingning County, Jingning She Autonomous County, Lishui City, Zhejiang Province is 30 tons/day, the core process is to use MABR oxygen permeable membrane to transfer oxygen to the attached growth of biofilm, to achieve synchronous nitrification and denitrification, remove organic matter and reduce ammonia nitrogen, effluent into the secondary sedimentation tank for slurry water separation, the separated supernatant after ultraviolet disinfection to kill germs and microorganisms into the constructed wetland, in the constructed wetland microorganisms and plant absorption under the action of further denitrification and phosphorus removal, Finally, it is discharged into the surrounding water bodies, and the effluent meets the second-level standard in the "Water Pollutant Discharge Standard for Rural Domestic Sewage Centralized Treatment Facilities" (DB33973-2021), and has successfully passed the completion acceptance of the project. This project is the first demonstration project application of domestic low-carbon MABR sewage treatment process equipment in Zhejiang Province completed by Yinjiang Environmental Protection.
