Water treatment, Nano BubblesGreenhouse
Vortex UFB Unit
The Vortex UFB unit has been designed to release ultra-fine oxygen bubbles into a storage tank and other forms of water holding systems. The unit consists of a pump, filter, check valve, venturi, pre-mixer, cone-vortex combination, in-line Dissolved Oxygen (DO) sensor, pressure sensor, oxygen concentrator and a control box. This all mounted on a frame.
The Vortex unit scrubs the air for oxygen. Through the patent-pending vortex technology it applies force to the oxygen, pulverizing the O2 into the irrigation water, and creating Nano Bubbles. By doing this the O2 stays in suspension even when going through several process of an irrigation system.
What are Nano-Bubbles?
Nano bubbles are tiny spherical cap-shaped bubbles with diameters less than 100 nm that have the ability to change the normal characteristics of water. They have several unique physical and mechanical features, including stability, high internal pressure, extremely large surface/volume ratio, high oxygen dissolution rate, and generation of free radicals. The peculiar attributes of nanobubbles has led to their . wide application and utilization in various agricultural applications which are proven to be with high economic potential.
MAIN ADVANTAGES OF O2 NANOBUBBLES:
- Stable enhancement of Dissolved Oxygen (DO)
- Bubbles have a negative charge and promote cation-exchange
- Bubbles become a substrate (the water becomes an aerated foam)
- Free radicals increase metabolism
- Cell membrane permeability of larger molecules
- Fights disease through exclusion (healthier plants) instead of disinfection
Oxygenation of irrigation water with nanobubbles
A high oxygen level in the irrigation water is very beneficial for the plants if it reaches the rootzone. It is possible to super saturate the water with oxygen gas up to 300%. Oxygen level and temperature of the water have a certain equilibrium. The colder the water the more oxygen (O2) it can hold. The equilibrium level for water of 20 C0 (68 F0) is 9 mg/liter O2. When the O2 concentration in the water is lower than the equilibrium level and it is exposed to air it will take O2 however if the O2 concentration is higher than the equilibrium level it will lose O2. Through the movement of the irrigation water in pumps, tanks, pipes and sprinklers the O2 above the equilibrium level will be lost before it reaches the root zone.
Nanobubbles in irrigation
With a nanobubble generator in combination with a O2 concentrator it is possible to super saturate the irrigation water to > 250% O2 and keep that concentration stable for a long time because the O2 nanobubbles will dissolve slowly in the irrigation water what gives a constant production of Reactive Oxygen Radicals (ROS). It will reach the root zone of the plants at a level between 150 and 200% saturation.
The science behind Nano Bubbles
An ordinary bubble (1 mm diameter) will quickly rise to the waters surface and collapse. Based on the Brownian Motion Particle Theory, nano bubbles will randomly drift and remain in liquids for an extended period of time without being affected by buoyancy.
Nano Bubbles produce Reactive Oxygen Species ROS). These oxygen radicals and hydroxyl radicals help to eliminate hard to kill pathogens.
At 1-billionth of a meter, nano bubbles can delve deep into surface imperfections that even micrometer size bubbles cannot reach. Nano bubbles dig out and remove dirt and odors, leaving a clean surface behind.
- Nano Bubbles help organisms absorb oxygen and become more active.
- Oxygen Nano Bubbles promote the growth of micro-organisms and expedite the breakdown of organic matter.
- By improving the efficiencies of water treatment growers can increase the nutrient uptake in plants, see improved plant health and root quality, and reduced chemical usage.
Nanobubbles are bubbles one billion times smaller than a meter. They are so small you cannot see them with the naked eye only with laser equipment. Nanobubbles are produced with special generators. A nanobubble has a negative zeta potential and the pressure inside the bubble is high. Normal gas bubbles will rise to the surface and collapse. Nanobubbles will not rise to the surface and will be suspended in the water for a long time and will be getting smaller over time and release there O2 mostly in the water. Also, movement of the water will not nearly effect O2 in nanobubbles as O2 gas dissolved in water.

The horticultural sector worldwide faces the challenge of producing more food in an environment where water is becoming increasingly scarce and fertilizers increasingly expensive. More economical and efficient use and reuse of water play an increasingly important role. In addition, maintaining the quality of water and food safety will remain of great importance.
By minimizing the use of water and nutrients, each plant must receive exactly the right amount of water and nutrients.
At Hortilife, we know these challenges and make sure our solutions are future proof.
