【Wastewater Treatment】Eliminating DO Deficiency! Reasons and Effects of Choosing Oxygen Fighters
High Concentration Gas Dissolution Device - Oxygen Fighter
Eliminate the DO deficiency in wastewater treatment! The effects and installation examples of the "Oxygen Fighter" that can be retrofitted.
The "Oxygen Fighter," a high-concentration gas dissolution device, is effective in solving issues such as DO (dissolved oxygen) deficiency, oxygen deprivation, and odor problems at wastewater treatment sites. By using pure oxygen, it achieves a high dissolved oxygen level of 20-25 mg/L in a single pass. It can be retrofitted to existing facilities, eliminating the need for extensive renovations to resolve DO shortages. 【Three Installation Locations and Effects】 1. Raw Water Tank / Flow Adjustment Tank: Prevents decay before being sent to the aeration tank, reducing the processing load in subsequent stages. 2. Aeration Tank: Stabilizes DO and activates aerobic microorganisms. Maintains a high MLSS state and preserves processing capacity. 3. Return Sludge Line: Provides oxygen to settled sludge to activate it, circulating it back to the aeration tank, thereby improving the overall processing capacity of the system. 【Main Models Available (Selectable Lineup)】 OD-511 Model: Maximum flow rate 800 L/min, 3.7 kW OD-611 Model: Maximum flow rate 1400 L/min, 5.5 kW OD-911 Model: Maximum flow rate 3000 L/min, 11 kW We will propose the optimal installation location based on the site conditions and available space.

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.
