1. Advanced Aeration, Inc. Presentation of Vacuum Bubble® Technology
Traditional aeration uses buoyant bubbles
buoyant bubbles float to surface
contact/DO delivery time is minimal
buoyant bubbles are expensive to generate
Aerob-A-Jet bubbles are tiny
vacuum bubbles are created under a partial vacuum
tiny bubbles remain suspended for hours (.25 mm for hours)
they readily diffuse and disperse
optimize aerobic bacterial growth
VBA (Vacuum Bubble Aeration) technology replaces large motors
3 hp can replace a 25 hp motor (traditional aeration)
VBA is maximized with less mixing
Even better results if sludge is not disturbed !!
For high strength wastes, VBA has no equal !
traditional aeration can’t handle BOD above 2-3,000
VBA can handle 9,000 BOD!
Converts anaerobic to aerobic
can dramatically improve aerobic performance in any BOD application
Traditional aeration is very common and well established
numerous large companies with established world-wide market-share
old method of traditional aeration has NSF approval
[The competitive landscape
Provide an overview of product competitors, their strengths and weaknesses
Position each competitor’s product against new product]

3. Today’s Challenges in Wastewater Treatment
Wastewater Engineers are constantly challenged to:
Reduce accumulated solid waste.
Reduce power consumption.
Reduce undesirable odors.
Reduce contaminants in discharged water (Improve water quality).

5. Wastewater Treatment
All forms of wastewater consist of both organic and inorganic contaminants:
Solids that can settle out, suspended solids (cloudy water), and dissolved components.

6. Wastewater Treatment
Inorganic contaminants are usually handled with physical and chemical processes:
Settling – gravity working for you
Filtration – screens, skimmers, etc.
Special equipment & chemicals
Oil/water separators
Dissolved air floatation (DAF) systems
Polymers & floculants

7. Wastewater Treatment
Biological treatment processes focus on the organic content in wastewater.
Microscopic organisms (bacteria) degrade dissolved organic compounds rapidly to generate energy and build new bacteria.
Excess organic loading can result in too much accumulated activated sludge.

8. Wastewater Treatment
Substantial contact time is required for bacteria to degrade organic matter.
Bacteria can rapidly degrade dissolved contaminants in water.
Solids are degraded more slowly over time.

9. Bacteria Three types – Anaerobic – Slow and smelly (H2S and CH4).
Aerobic – Prolific, efficient and clean (CO2 and H2O).
Facultative – can be either aerobic or anaerobic.

10. Optimize Organic Degradation
Tilt the balance of microbial activity toward Aerobic digestion.
Achieved through optimization of Oxygen Transfer Potential.
Utilize Aeration technologies.

12. Aeration How is VBTTM different?

13. Aeration - Methods Many are only mixers or circulators.
True aeration introduces bubbles
into water.

14. Forced Air Bubble Formation
Compressed air diffusers and Venturi systems all create bubbles with internal pressures greater than external pressures in the water column.

15. Vacuum Bubble® Formation
VBTTM patented bubble production creates bubbles with internal pressure slightly less than external pressure of the water column.

16. Vacuum Bubble® Formation
VBTTM bubbles shrink until reaching equilibrium.
VBTTM bubbles stay in the water for several minutes.

18. Bubble Sizes One 20mm Bubble = Surface Area – 12.6cm2
Total Surface Area – 84cm2
6x greater than 20mm Bubble
- 500, mm Bubble
Total Surface Area – 1000cm2
80x greater than 20mm Bubble
12x greater than 3mm Bubble

19. Bubble Size and Aeration Time: Size: Movement:
Bubbles stay in the water for minutes
Size:
Smaller bubble size = greater surface area
Movement:
Bubbles move sideways by diffusion
