Solari Microbubble and Nanobubble Generator
Documents & Case studies
What is a Nanobubble ?
Microbubbles and nanobubbles or ultrafinebubbles are tiny bubbles with a respective diameter of 10–50 μm and <200 nm. This is a new technology that is currently being explored for various applications. Nanobubbles or ultrafinebubbles offer environmentally sustainable water solutions with a broad range of applications in a variety of industries.
The Solari Microbubble and Nanobubble Generator is a non-chemical system that uses air (or any gas) to effect solid-liquid separation, thereby reducing the total suspended solids (by more than 99%).
Save Money, Chemicals, Time & Energy
Water treatment means the use of coagulation and flocculation chemicals. These are expensive and produce sludge through the liquid-solids separation. In some instances, these chemicals could further hinder the treatment process.
Reduce the organic load in the water.
The Solari Microbubble and Nanobubble Generator is able to reduce the organic loading considerably in the waste stream. Typical performances reductions of COD > 80% and BOD> 50%
Nanobubble water controls disease and promotes significant advanced growth.
In the past few years, more and more attention has been given to the potential applications of the MBs and NBs for water treatment.
Water Reuse And Recovery
Reduce the organic loading considerably in the waste stream.
Cooling Tower Water
Generation of highly reactive free radicals and turbulence associated with the collapsing MBs provides great potential for water disinfection.
Proven to be a new environmental friendly technique for oxidation of organic compounds.
Providing faster germination and higher crop yields as well as sanitisation of leafy vegetables.
Fresh Produce Washing
Pathogens like the norovirus in oysters or e-coli in spinach or listeria in frozen vegetables is a major issue for processors around the world.
It has been shown that adsorption of proteins onto various surfaces could be inhibited by NBs, thus preventing the surfaces from fouling
A bit about the technology…
Microbubbles in liquid greatly enhances the surface area for enhanced mass transfer of the gas into the liquid. After mixing there is decompression of the high pressure combined gas/liquid and this forms fine charged emulsion of ~30-50 micron size. Electrical charges on the extremely fine gas bubbles prevent it from coalescing and reduce its rising velocity. Microbubbles can’t break the surface.
Therefore residency time is increased. The surface area of the bubble is inversely proportional to the diameter; increasing the surface area of the gas. This increases the mas transfer co-efficient. Volumetric mass transfer co-efficient can be increased by 5-6 times. As the bubbles slowly rise the high surface area transfer the gas to the liquid. This increased mass transfer reduces the bubble size increasing the pressure of the gas (Laplace Pressure) in the bubble. At the same time the surface charge of the bubble increases its Zeta Potential. This then attracts minute suspended particles to the bubble. As the minute particles are smaller than the bubble size, the Total Suspended Solids of the liquid reduces, and water clarity increases tremendously. As the bubbles rise, the pressure inside increases and the bubble eventually bursts. This creates extreme heat, radicals and Ultrafine Bubbles (nanobubbles). All of this aids greatly in the production of radicals and gives high oxidation and disinfection.
We can Make The World a Better Place
By helping industries move as far away from chemical induced treatment as possible. The water industry has been seeking a non-chemical treatment processes. The Solari Microbubble and Nanobubble Generator is a non-chemical system that uses air (or any gas) to effect solid-liquid separation, thereby reducing the total suspended solids (by more than 99%).
