Nano Bubble Column System

Maximum Dissolution. Controlled Environment. Superior Stability.

The Nano Bubble Column System is engineered for applications where gas transfer efficiency and contact time are critical. Through the use of ultrafine-pore generation technology, this system produces an exceptionally dense concentration of nano bubbles within a controlled vertical column.

This environment allows for extended interaction between gas and water, significantly improving dissolution rates and enhancing the stability of nano bubbles once they leave the system. The result is a highly effective treatment process capable of supporting advanced oxidation, disinfection, and water quality improvement.

The column design allows for precise control over both gas input and water flow, making it suitable for applications that demand consistent and measurable performance. It is particularly valuable in systems where accuracy and repeatability are essential.

The Nano Bubble Column is an advanced oxygenation device designed for aquaculture and water treatment applications. Using a proprietary nano pico bubble generation method, The Nano Bubble Column supplies oxygen efficiently from the bottom of the water, delivering long lasting oxygen throughout the entire water body.

Unlike conventional aeration methods, The Nano Bubble Column generate ultra fine oxygen bubbles that remain suspended in water for extended periods, allowing oxygen to reach distant areas and deeper zones where conventional air bubbles cannot.

Key Characteristics
  • Generates nano pico oxygen bubbles that remain in water for a long time
  • Supplies oxygen from the bottom of the water body
  • Mixes air efficiently into water
  • Releases oxygen directly underwater
  • Enables oxygen delivery over a wide area, including distant locations
  • Effective even in deep water installations
Technical Features
  • Oxygen Behavior in Water
  • Oxygen dissolved in water increases efficiently
  • Nano pico oxygen bubbles remain suspended instead of immediately escaping
Oxygen can reach
  • The bottom of the tank or pond
  • Areas far from the installation point

In contrast, conventional aeration systems release large bubbles that rise quickly to the surface. Except for saturated dissolved oxygen, most of the supplied oxygen escapes into the air before it can be utilized. As a result, oxygen often fails to reach the bottom or distant areas of the water body.

Effects on the Water Environment

With The Nano Bubble Column and Oxygen Supply System

  • Oxygen spreads evenly throughout the entire water area
  • Reduces the risk of oxygen deficiency, even when water temperature rises
  • Enhances the activity of beneficial microorganisms
  • Promotes decomposition of organic waste and sludge
With Conventional Aeration
  • Oxygen tends to concentrate only near the aeration point
  • Oxygen deficiency may occur as water temperature increases
  • Strong water flow can cause stress to aquatic organisms

Effects on Aquaculture Production

The introduction of The Nano Bubble Column has demonstrated the following benefits in aquaculture environments:

  • Significant reduction in mortality rates
  • Accelerated growth of fish and aquatic organisms
  • Shorter farming periods
  • Lower electricity consumption and operating costs
  • Electricity Cost Comparison in Aquaculture
  • Typical Power Requirements
System Type Power Consumption
The Nano Bubble Column (Compressor) 550 W
Water Wheel 750 W
Turbo Blower 1,600 W
Operating Characteristics
The Column:
  • Uses power only when storing air in the tank.
  • Approx. 72 minutes of operation per day.
Water Wheel / Turbo Blower:
  • Operates 24 hours per day, 365 days per year, resulting in significantly higher energy consumption.
Comparison of Oxygen Supply Methods
  • The Nano Bubble Column
  • Agitates water and supplies oxygen simultaneously
  • Generates nano pico bubbles from the bottom of the water
  • Operates effectively even in deep water
  • Nano pico bubbles transport oxygen over a wide area
  • Increases overall oxygen concentration
  • Prevents oxygen deficiency
  • Reduces deformities and mortality rates
  • Improves feeding behavior and accelerates growth
  • Water Wheel
  • Mixes water and supplies oxygen near the surface
  • Turbo Blower
  • Releases large volumes of air underwater
  • Most oxygen escapes before being utilized
  • Proven Use in Freshwater Aquaculture (Japan)
In Japan, The Nano Bubble Column Generators have been successfully used in freshwater fish farming, including:
  • Masu salmon
  • Iwana (char)
  • Amago trout
  • Yamame trout

Nano pico bubbles generated at the water intake remain suspended and transport oxygen not only as dissolved oxygen, but also as oxygen containing bubbles to distant farming tanks. This enables stable oxygen conditions across large facilities.

Observed Results from Field Applications
  • Fish gather quickly when feed is dispersed, even at low water temperatures
  • Appetite remains strong in cold conditions
  • Fry remain healthy and energetic
  • Mortality rates decrease significantly
  • Fish losses previously caused by reduced river flow are eliminated
  • Stocking density can be increased without compromising fish health

It is believed that oxygen containing nano pico bubbles spread throughout the entire water body and positively affect microorganisms at the bottom of the tank or pond

Nano Pico Bubbles and Dissolved Oxygen
  • Dissolved oxygen represents the maximum amount of oxygen that can dissolve in water
  • This maximum decreases as water temperature rises
  • Approx. 7 mg/L at 30°C

Nano pico bubbles supplied by The Nano Bubble Column cannot be measured by standard dissolved oxygen meters. However, in the Column equipped ponds, oxygen exists both as dissolved oxygen and as suspended nano pico bubbles. Because of this dual oxygen presence, oxygen deficiency is unlikely even when measured dissolved oxygen levels appear low.

High Temperature Aquaculture Application

In a Taiwanese sea bass farm using The Column:

  • Tank volume : 50 tons
  • Fish count : 800
  • Water temperature : 30°C
  • Measured dissolved oxygen : 4 mg/L

Despite the low dissolved oxygen reading, The Nano Pico Bubble Column and Oxygen supplied sufficient oxygen to maintain healthy fish conditions.

Application of The Nano Bubble Column Technology in Land Based Aquaculture

The Nano Bubble Column uses a unique porous membrane bubble generation method that enables nano pico bubble production even in deep water.

Key Benefits:
  • Oxygen and nitrogen penetrate sludge at the bottom of tanks
  • Oxygen reaches feces and organic waste
  • Activates beneficial aquatic microorganisms
  • Enhances nitrifying bacteria activity
  • Converts toxic ammonia and nitrite into less harmful nitrate
  • Improves overall water quality
  • Promotes growth and reduces mortality rates

The Nano Bubble Column provides a highly efficient, energy saving solution for oxygen management in aquaculture. By delivering long lasting nano pico bubbles throughout the entire water body, The Nano Bubble Column improves oxygen availability, water quality, and biological stability, resulting in healthier aquatic organisms and lower operating cost.
