What is the difference from nanobubbles? Oxygen fighter that prevents the rapid drop in DO in aquaculture.
High Concentration Gas Dissolution Device - Oxygen Fighter
Measures against oxygen deficiency in aquaculture: Rapid recovery from the sharp drop in DO after feeding with 'Oxygen Fighter' that cannot be compensated by nanobubbles.
The "nanobubble," known for its measures against oxygen deficiency in aquaculture, and the high-concentration oxygen dissolution device "Oxygen Fighter." Both are facilities that supply oxygen, but there are clear differences in their mechanisms and "resilience to crises." The main difference is whether it involves "bubbles" or "dissolution (water)." Nanobubble: A technology that suspends ultra-fine "bubbles" in water, gradually dissolving them over time. Oxygen Fighter: A technology that instantly dissolves oxygen into the water itself without producing bubbles (almost bubble-free). This difference becomes a decisive factor in situations where there is a "sudden drop in DO (dissolved oxygen)" right after feeding or during the summer. Nanobubbles have a time lag before the bubbles dissolve, which can result in the supply not keeping up with rapid oxygen consumption. On the other hand, the Oxygen Fighter generates ultra-high-concentration oxygen water with DO levels of 20-25 mg/L in just one pass through the device. It can be rapidly injected into tanks facing oxygen deficiency, quickly recovering to a safe oxygen level. "Operate the Oxygen Fighter only when DO is needed, while leaving the regular water flow to existing blowers." This division of roles is a reliable defense strategy that reduces gas costs while eliminating the risk of oxygen deficiency.

basic information
We have a total of 20 models with a maximum flow rate of 60L/min to 5000L/min, including both freshwater 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 propose 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.
