NanoDAF™ | Advanced Dissolved Air Flotation System
High-Efficiency Clarification for Industrial and Municipal Wastewater
NanoDAF™ is InfraCorp’s high-performance Dissolved Air Flotation (DAF) system, designed for the rapid and efficient separation of fats, oils, and grease (FOG), total suspended solids (TSS), biological oxygen demand (BOD), and a wide range of industrial and food-processing contaminants.
Engineered for demanding applications, NanoDAF™ leverages microbubble flotation technology to deliver superior clarification performance—with removal efficiencies of up to 97% or higher for critical pollutants.

Complementary InfraCorp Technologies
To build a full treatment solution tailored to your needs, NanoDAF™ seamlessly integrates with other InfraCorp technologies, including:
BioSep™ – MBBR Biological Treatment
Advanced MBBR biological treatment with proprietary NanoChip™ media for high-rate organic and nutrient removal
EcoLeach™ – Adaptive Leachate Treatment
Adaptive leachate treatment combining biological, chemical, and physical processes
Min™ZLD – Zero Liquid Discharge Solutions
Efficient zero liquid discharge (ZLD) solutions for industrial wastewater recycling and volume reduction
Air Mixing Optimization Process
InfraCorp has optimized the air mixing process by mixing a percentage of the clean effluent is recycled and super-saturated with air, mixed with the wastewater influent and injected into the DAF separation chamber. Air is injected under pressure into a recycle stream of clarified DAF effluent.
This recycle stream is then combined and mixed with incoming wastewater in an internal contact chamber where dissolved air comes out of solution in the form of very fine bubbles that attach to the contaminants. The bubbles and the contaminants rise to the surface and form a floating bed of material that is removed by a surface skimmer into an internal hopper for further handling. This handling may include a belt filter press or a rotary vacuum drum with DE applied.
NanoDAF™ Key Benefits
Ultra-Efficient Clarification: High-efficiency removal of suspended and colloidal materials in a wide range of industrial wastewater streams.
Microbubble Advantage :Proprietary saturation and release system creates ultra-fine bubbles for superior particle capture and flotation performance.
Compact, Modular Design :Ideal for retrofits, system upgrades, or integration into full treatment trains (e.g., BioSep™, EcoLeach™, Min™ZLD).
Low Maintenance, High Uptime :Built with industrial-grade components for continuous, dependable operation in demanding environments.
Versatile Industry Fit :Designed for applications in food & beverage, dairy, meat processing, petrochemical, textile, and more.
NanoDAF™ is an alternative clarification process ideal for treating raw water with light particles, such as algae or color-causing organics, and at lowtemperatures when sedimentation is not as effective .DAF has become a mainstream clarification process for drinking water treatment plants, especially where algae is prevalent, as well as a popular pretreatment process for seawater desalination systems to combat red tide or algae bloom occurrences throughout the world.
