Super-nano aerosol oxygenation system (high-pressure type)
Category: Super Nanometer Aerosol Oxygenation System
Product Details
The theoretical basis of super-nanobubble aeration technology is to utilize Henry's Law to increase the dissolved oxygen saturation in water by increasing the pressure in the dissolved gas tank. Simultaneously, combined with the internal structural design of the dissolved gas tank, such as the upper and lower bottom radii and the height of the dissolved gas tank, supplemented by the control of the inflow and inflow rates, it ensures that the initial oxygen bubbles have a residence time of more than 60-90 seconds, increasing the proportion of nanobubbles and reducing the probability distribution of microbubbles.
| Equipment Type | Scale | Oxygen Utilization Rate | Bubble Grade | Maximum Service Area per Unit | Water Body Disturbance | Residence Time | Power Efficiency | Other Characteristics |
| Super-Nanobubble Aeration System | 60 | Over 95% Bottom Oxygenation | Nano-level (Invisible to the naked eye) | 220,000-450,000 | No Disturbance | Over 30 days | 2.5-4.0 | 1. Supersaturated dissolved oxygen concentration in effluent, no visible bubbles; 2. Oxygen transfer efficiency over 90%; 3. Will not disturb the bottom of the water body, long residence time, can quickly improve water quality; 4. Can be fixed or mobile, applicable to rivers, canals, lakes and many other scenarios. |
| Micro-nano Aeration System | 60-90 | Below 20% Mid-upper layer oxygenation | Micron-level | 50-300 | Mid-upper layer Strong disturbance | Less than 2 hours | <1.0 | 1. Effluent dissolved oxygen concentration within saturation; 2. Oxygen transfer efficiency below 40%; 3. Limited effect on water quality improvement; 4. Commonly used in river governance, frequent maintenance. |
| Conventional Aerator (Fountain, Push Flow) | 30-90 | Below 10% Surface Oxygenation | Millimeter-level | 10-50 | Surface Severe disturbance | Less than 1 hour | <0.2 | 1. Effluent dissolved oxygen concentration within 70% saturation; 2. Easy installation, small footprint; 3. Commonly used in outlet treatment or landscape water treatment. |
