Nano Generators

Fine Nanobubble and Micro-Oxygen-Ozone Nanobubble Generator

Puroxi Nanobubble generators transfer any gas into any liquid with near-perfect efficiency. The system does this via a unique two-phase gas transfer system that saturates a liquid with both dissolved gas and trillions of Nanobubbles in the 50-200 nm range, providing greater than 200x the interfacial surface area compared to microbubbles. Nanobubble aeration has a distinct advantage over traditional aeration since the Nano bubbles remain suspended for prolonged periods, creating a reserve of available gas in the liquid. This low turbulent gas diffusion process results in the most efficient method to enhance the performance and functionality of any liquid.

Microfloatation with Microbubble

Microfiltration is a further development of standard dissolved air flotation (D.A.F.). Micro flotation is a water-treatment technology operating with 10–50 μm microbubbles instead of 80-300 μm like conventional D.A.F. units.

The general operating method of micro flotation is similar to standard recycled stream D.A.F. units. The advancements of micro flotation are lower pressure operation, smaller footprints and less energy consumption.

Description of function of a standard D.A.F. (Dissolved air flotation)

D.A.F. is a water treatment process that clarifies wastewater (or other waters) by removing suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles that adhere to the suspended matter, causing the suspended matter to float to the water’s surface, which a skimming device may then remove.

The micro flotation method is comparable to recycled stream D.A.F. A portion of the clarified effluent water leaving the Micro flotation tank is pumped into a small pressure vessel into which compressed air is also introduced. This results in saturating the pressurized effluent water with air. The air-saturated water stream is recycled to the front of the Micro flotation cell. It flows through a pressure release valve just as it enters the front of the float tank, releasing the air in the form of tiny bubbles. Bubbles form at nucleation sites on the surface of the suspended particles, adhering to the particles. As more bubbles form, the lift from the bubbles eventually overcomes the force of gravity. This causes the suspended matter to float to the surface, where it forms a froth layer, which is then removed by a skimmer. The froth-free water exits the float tank as the clarified effluent from the Microflotation unit. A circular D.A.F. system is called “Zero speed,” allowing quiet water status and then the highest performances; a typical example is an Easy float 2K D.A.F. system.

Advantages

Microflotation is an enhanced method to float particles to the surface with adherent air bubbles.

Adhering suspended solids to bubbles is easier and more intensive the smaller the bubbles are. Because of the improved adherence capacity of tiny microbubbles, the saturation of the introduced air, as well as the reduction capability of particles, lead to an enhanced suspended solids reduction, a higher solids content in the floating sludge and a more stable float sludge on the surface, of the micro flotation cell.

A difference must be made to disperse flotation used in the mining industry in mineral segregation processes where the bubble is more significant, 500-2000 μm in size. The volume of air is many folds compared to the

water volume. Traditional Dissolved Air flotation (D.A.F.) mainly operates with bubble sizes ranging from 80-300 μm with very inhomogeneous bubble size distribution.  Microbubble cloud in a Microflotation cell.

A significant difference between pressure-dissolved air flotation and other flotation processes lies in the volumes of bubbles, amount of air and rising speeds. One macro bubble can be 1000 times more giant in volume than one microbubble. And vice versa, the number of microbubbles can be 1000-fold compared to one macro bubble having the same volume.

Micro flotation enables 40-50 μm bubbles with rise rates from 3–10 m/h. The rising rate is slow enough not to destroy the fragile flocks, forming an agglomeration of particles with weak mutual bonding and high enough to allow time for the separation of the agglomeration. With the attachment of particles to bubbles, the size range of “flock-bubble” grows, and the rising velocities are produced simultaneously. The accelerated separation rate leads to residence times of combined chemical precipitation and flotation from 10 to 60 minutes with the need for small footprint areas of treatment plants and decreasing the cost structures of treatment processes.

A distribution of bubble sizes between 20 and 50 microns is necessary for an optimum flotation result. Even a small number of bubbles with diameters above 100 microns can turn off a flotation separation process because more giant bubbles rise more quickly and cause turbulence, which severely destroys already-built air-flocks-agglomerates.

Applications

Microflotation is technically appropriate and primarily economic to substitute classic technology like sand filtration and sedimentation. Beyond, there are several applications in which low-pressure Microflotation is an alternative to membrane technology or represents a convincing addition. 80m3/h application

Microflotation can be used as:
  • Non-Chemical/Chemical Industrial Pre-treatment (C.O.D., B.O.D., F.O.G., T.S.S. reduction. heavy metal- and colour removal)
  • Primary treatment
  • Tertiary treatment
  • Replacement or protection of filtration units
  • Sludge thickening

Protection and performance improvement of MBR units (Membrane bioreactors), a combination of membrane processes like microfiltration or ultrafiltration with biological wastewater treatment process (removes and eliminates contaminants from wastewater and converts this into effluent, then it’s returned to the purification cycle.) aerobic and anaerobic biologies

Features for D.A.F. Applications
  • High rate of suspended solids removal
  • Supplying a highly dense microbubble output
  • Highly consistent dissolved air flotation
  • Fine adjustments are not necessary when operation or start-up
  • Easily retrofit to pre-existing systems
  • Small installation footprint
  • Minimum power consumption
  • Low power required (no compressor required)
  • Easy maintenance and minimum operational cost
  • Compact and straightforward pump structure
  • Quiet operation
  • No compressor, level controls, or saturation tank required

The micro flotation performs three functions simultaneously: suction, mixing, and pressurization, which is ideal for D.A.F. and liquid-gas applications. Its reliable performance results in a highly stable overall system.

What we need:

1. We would require the volume of water you are trying to treat.

What you buy locally:

1. All plumbing parts

2. An electrical plug you want to attach to the Nano Generator wires.

3. A surge protector plugs in for the Nano Generators.

4. The right amount of disk aerator stones (Amazon has these).

The body or water setup:

1.  The plumbing goes from the water source (soft or solid plumbing like PVC, etc.) into the Nano Generator (Nano Generator is Supplied).

2. Next, you install the pressure tank (Pressure Tank is Supplied).

3. Then there is the plumbing that goes to the water body, and you create a manifold with a vertical pipe that is also solid with several outlet pipes. Ask for the video on a river application to see this in action. It would be best to use dependable, trustworthy, solid plumbing so that the Nano Bubbles do not sit in gaps and valleys of flexible plumbing.

4. Now install the disc aerator stone at the end of each outlet in the water body. These go to the outlet pipes’ end, where the Nano Bubbles are now put back into the water body.

5. This system can be moved to different areas to create a good mixture of Nano Bubbles in the complete water body, or you can purchase more units so you do not have to move them.
