Filtoflex – overview of the technology
Filtoflex’s advanced technology is designed to generate cost-effective and sustainable nanobubble gas to inject air, oxygen or ozone into any liquid.
The Filtoflex technology greatly improves the gas-liquid phase process to efficiently generate nanobubbles at a low cost.
Our nanobubble technology can be used in hydroponic and soilless production systems to increase the quantity and quality of production.
Once the crop is grown, Filtoflex helps packaging houses with post-harvest applications like disinfection and cleaning while reducing the use of chemicals. Filtoflex technology can also be used to treat water and wastewater.
Nanobubbles are extremely small gas bubbles, less than 200 nanometers in diameter, with many unique physical properties that make them very different from macro or micro bubbles. These unique characteristics make nanobubbles the ultimate choice for the aeration of liquid media.
Due to the extremely small size, nanobubbles are not buoyant enough to reach the surface and instead follow Brownian motion allowing nanobubbles to be extremely stable and remain in solution – evenly distributed across the entire volume of liquid – for months, unlike macro or micro bubbles.
All bubbles posses a surface charge, however the surface charge of a bubble increases as the bubble diameter decreases. This gives nanobubbles a very high surface and charge and a high zeta potential, the electro kinetic potential in colloidal dispersions. The strong negative charge of nanobubbles improves separation efficiency in flotation by increasing collision probability with the particulate matters.
The internal pressure of nanobubbles in liquids is much higher than that of their environment, which accelerates the dissolution of the gas into the liquid. Therefore, the liquid will maintain saturation status for the target gas, this is not the case for macro or micro bubbles.
These unique characteristics of negative charge, high surface area (relative to volume), and stability in solution make nanobubbles the best and most efficient gas transfer option.
