vDAF
Spiral Vortex Flotation Separation System
A VORTEX-BASED FLOTATION SEPARATION SYSTEM THAT GENERATES THE MOST MICROBUBBLES
Generation of ultra-fine microbubbles using a spiral vortex and a bubble-generating nozzle
Average bubble diameter of 25 μm or less, bubble concentration of 100,000 bubbles/mL or more ( verified by the Korea Institute of Machinery and Materials)
State-certified performance certification technology (No. 27-422)
Why Ultrafine Bubbles?
The smaller the bubble size, the more effectively the system can float and remove even the tiniest particles
Increased opportunities for solids adhesion minimize the need for excessive coagulant dosing
Applications
We help our customers discover hidden benefits.
Tertiary wastewater treatment
Wastewater reuse
Traffic Separation Improvement Project
Gas dissolution
Features
Excellent SS Removal Rate
Ultra-fine bubble concentration over 5 times higher than that of competing products, minimizing sludge loss
Ultrafine bubbles generated by the high-speed collision of highly concentrated dissolved water remove even the finest particulate matter
Forms a high-density bubble bed to minimize the settling of floating sludge and sludge loss
RETROFIT EXISTING DAF
Save energy up to 60%
150% increase in processing capacity compared to conventional reactors
Minimize the power required for bubble generation
Reduce coagulant dosing reduce the generation of sludge volume
Reduced operating and maintenance costs through increased reactor processing capacity
