THA River and Lake Purification System that activates the self-purification process of rivers and lakes.
High Concentration Gas Dissolution Device - Oxygen Fighter
What is the THA river and lake purification system that activates self-purification functions, certified by NETIS?
The deterioration of water quality in rivers and lakes is primarily caused by a lack of oxygen at the bottom and an increased oxygen demand due to inflowing pollutants. In response to this issue, our high-concentration gas dissolution device "Oxygen Fighter" has been registered in the Ministry of Land, Infrastructure, Transport and Tourism's new technology information provision system "NETIS" since 2001. This system's main feature is its ability to dissolve oxygen in water with almost no bubbles. Unlike traditional aeration methods, where bubbles rise and escape into the atmosphere, it directly delivers high-concentration oxygen to the bottom of the water, where it is most needed. By increasing the dissolved oxygen (DO) at the bottom, aerobic microorganisms are activated, initiating the food chain and dramatically promoting the self-purification of water quality by organically decomposing and reducing sediment (sludge). We offer a lineup of 12 models capable of handling a maximum flow rate of 5,000 L/min, allowing for optimal selection based on the scale of the site. Our technology has been adopted in purification facilities in Tokyo's Nonogawa and Meguro rivers, and we have a wealth of experience in the aquaculture sector and JICA projects.

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 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.
