The “New Definition” of diffuser

Aquablaster technology

Often Neglected Important Knowledge:

It is not only the type of Microorganism that is important in waste water treatment but also their METABOLISM.

  • 1 Inhaling sludge and water from bottom and giving strong impact
    Aquablaster mechanism 1
  • 2 Creation of microbubbles by specific blades
    Aquablaster mechanism 2
  • 3 Crushing sludge helps microorganism to metabolize efficiently
    Aquablaster mechanism 3
  • AQUABLASTER can contribute to reduction of running cost

    • Creation of microbubbles increases dissolved oxygen inside tank
    • Increase of D.O helps microbial metabolize (Aerobic fermentation) efficiently
    • Crushing sludge helps microbial activity
    • Pressure loss equals to zero
    Expected Output
    • Improvement of treatment capacity
    • Contribution to reduction of electricity consumption
    • Contribution to reduction of odor such as H2S
    • Contribution to reduction of sludge discharging costs
    • NO need for maintenance cost
    • Contribution to reduction of BOD, SS, and oil
    • Contribution to reduction of chemicals

    AQUABLASTER has already been installed to many fields like chemical plants, food processing, automaker (Toyota, Daihatsu, Oji, Yamaha), Hotel Okura, Hayashibara, Ueno, and Tokuyama etc.
