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 oil and 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 BOD removal rate improved significantly to 80%, and the removal rate of n-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 to 2020 over eight years:
- With a 6-hour retention time in the adjustment tank, BOD and n-hex were cut by over 80%.
- The floating oil and grease and settled sludge that had been generated in the adjustment tank have not been removed even once in eight years.
- Hydrogen sulfide levels decreased from 100 ppm to 0 ppm.
- At the outlet of aeration tank 1, the Setouchi regulations are being met.
- The sludge conversion rate for BOD was 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.
