Methods for Managing Dissolved Oxygen to Increase Productivity in Aquaponics
High Concentration Gas Dissolution Device - Oxygen Fighter
Oxygen fighters will change! The productivity and stability of aquaponics.
In "aquaponics," which combines fish farming and hydroponics, the concentration of dissolved oxygen (DO) in the water greatly affects productivity. Traditional aeration has a limit of about 5 to 7 ppm, but by introducing a high-concentration oxygen dissolution device called the "Oxygen Fighter," it becomes possible to supply ultra-high concentration oxygen water exceeding 20 to 40 ppm even at room temperature. This difference brings overwhelming advantages to the system. First, because the dissolution efficiency is nearly 100%, there is no gas loss, which helps reduce running costs. Furthermore, it allows for a significant increase in stocking density (overcrowded farming) that was previously limited due to concerns about oxygen deficiency, dramatically improving productivity per unit area. Additionally, the activation of nitrifying bacteria that decompose harmful ammonia greatly reduces the risk of water quality deterioration. The feeding rate and growth speed of seafood are also accelerated, leading to a reduction in the rearing period. The presence or absence of the Oxygen Fighter is the key factor that fundamentally changes the "stability" and "profitability" of aquaponics.

basic information
We have a total of 20 models with a maximum flow rate of 60L/min to 5000L/min, including both fresh and seawater. Our company sets the performance standard for dissolution at 20.0mg/L to 25.0mg/L during one pass (when water is flowing). We will suggest the appropriate model selection based on the required oxygen amount, so please feel free to contact us first.

Company information
At Daiei Manufacturing Co., Ltd., Environmental Division, we propose a high-concentration oxygen dissolution device as an alternative to conventional aeration methods. We aim to contribute to the establishment of a healthy social environment by utilizing this oxygen dissolution technology. In rivers and lakes, we create a saturated dissolved oxygen state near the bottom, promoting the activation of aerobic microbial communities. In industrial wastewater, high concentrations of dissolved oxygen have also made it possible to address high-load, high-density activated sludge (microorganisms). It is also used for the dissolution of gases other than oxygen.
