【Wastewater Treatment】Eliminate DO deficiency! Improve odors and hydrogen sulfide with high-concentration gas dissolution.
High Concentration Gas Dissolution Device - Oxygen Fighter
Improvement case of DO/ORP by oxygen fighters
The "Oxygen Fighter" is a high-concentration gas dissolution device that creates high-concentration oxygen water with a reverse idea of "allowing water to pass through gas." Unlike conventional aeration, it dissolves oxygen with almost no bubbles. By using "pure oxygen" instead of "air," it achieves approximately 4.8 times the dissolved oxygen (DO) level found under natural conditions. It minimizes losses as oxygen escapes into the atmosphere like bubbles, providing oxygen in an extremely efficient manner. In actual sites where it has been implemented, dramatic environmental improvements were observed in just one week. Before operation: DO 0.03mg/L / ORP -198mV (a state prone to severe oxygen deficiency and hydrogen sulfide generation) One day later: DO 1.6mg/L / ORP -33mV (improvement trend within 24 hours) One week later: DO 4.5mg/L / ORP +88mV (improvement to aerobic conditions) - Achieved effects - ● Suppression of bad odors and hydrogen sulfide generation (transition from a reducing state to an aerobic state) ● Improved sedimentation of sludge (enabling the recovery of clear supernatant water) The power consumption is also low, ranging from 2.2kW to 3.7kW for medium-sized units, allowing for operation with reduced running costs.

basic information
We have a total of 20 models with a maximum flow rate ranging from 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.
