Case study of microbubble adoption: Micro-nanobubble generation device "YJ Nozzle"
Case Study: Microbubble Generation Device "YJ Nozzle"
Microbubbles enable the elimination of odors, reduction of BOD, and decrease in chemical dosing in wastewater treatment facilities!
At Raw Material Manufacturing Company N, the introduction of the microbubble generation device "YJ Nozzle" has achieved the elimination of odors, reduction of BOD, decrease in chemical dosing, and volume reduction of flocculated sludge and excess sludge in wastewater treatment facilities. The modification involved installing one unit of the microbubble generation device YJ Nozzle "YJ-15" (0.75 kW submersible pump) in both the raw water tank and the adjustment tank. As a result, the long-standing issue of odors was completely resolved in just one day after the installation of the microbubble YJ Nozzle. Additionally, the Ministry of Land, Infrastructure, Transport and Tourism adopted the microbubble generation device for the Onga River Estuary Water Quality Conservation Project. To purify a water area measuring 400 meters wide and 1200 meters long, the microbubble "YJ Nozzle" was installed. Consequently, successful suppression of algal blooms and the occurrence of unpleasant odors and tastes was achieved. Before the improvements, it was thought that the introduction of an ozone advanced water treatment facility, which would require a huge investment, was necessary for the water supply facility drawing from this intake, but currently, that need has been eliminated.

basic information
【Improvements by Raw Material Manufacturing Company N】 ○ The odor, which had been a problem for decades, was completely eliminated just one day after installation. ○ The BOD of the raw water was significantly reduced from 7000 mg/ℓ to 3000 mg/ℓ after bentonite coagulation treatment. ○ The amount of chemicals used for bentonite was also halved, successfully reducing costs. ○ The frequency of extracting bentonite coagulated sludge was reduced from an average of 22 times per month to 11 times (halving waste disposal costs). ○ The surplus sludge from activated sludge treatment was also halved (halving waste disposal costs), achieving cost reduction. ○ The microbubble aeration, which has extremely low vibration and noise, contributed to environmental improvement. 【Ministry of Land, Infrastructure, Transport and Tourism】 [Expected Water Quality Improvement Functions] ○ Suppression of the leaching of nutrients and other substances through the supply and improvement of DO to the bottom chamber (improving the habitat for aquatic organisms). ○ Improvement of the water quality of the source water due to the volatilization of foul odor and taste components. [Effects After Installation] ○ Results were obtained as expected. ○ Successful suppression of the occurrence of blue-green algae and foul odor and taste substances. ○ Before the improvement, it was thought that the introduction of ozone advanced water treatment equipment requiring a huge investment was necessary, but currently, that need is no longer present. ● For more details, please contact us or refer to the catalog.
