The removal rate of BOD is 80%, and the removal rate of normal hexane extractable substances is 82%, showing significant improvement! Even after more than 8 and a half years, it maintains a no-maintenance state.
Before the installation of the Aqua Blaster, a large amount of grease scum accumulated in just one day, leading to the formation of oil balls. Hydrogen sulfide was generated to the extent that it corroded surrounding equipment. The oil balls on the water surface and those that sank to the bottom were regularly manually retrieved and disposed of as industrial waste. As a result of installing the Aqua Blaster, the removal rate of BOD improved significantly to 80%, and the removal rate of normal hexane extractable substances improved to 82%. Even after more than eight and a half years, there has been no need for removal or dredging work, and a no-maintenance state has continued. The dramatic improvement in water quality has led to waterfowl visiting the sedimentation tank every year without fail.
Below are the results from the installation in 2012 until 2020, covering eight years:
- With a six-hour retention time in the adjustment tank, BOD and n-hex were cut by over 80%.
- The floating grease and settled sludge that had accumulated in the adjustment tank have not been removed even once in eight years.
- Hydrogen sulfide levels, which were at 100 ppm, have been reduced to 0 ppm.
- The outlet of Aeration Tank 1 meets Setouchi regulations.
- The sludge conversion rate for BOD has been reduced from 35% to 25%.
- The sedimentation tank has remained stable, attracting ducks.
- Excess sludge has drastically decreased, and the odor from its steam drying is no longer a concern.
