*Data provided by the University of Hyogo

Swirling flows and microscopic air bubbles are generated by making the gas andthe liquid collide with thehard blades.

Zero internalpressure loss
Sludgeon the bottom
swept up
An airlift effect sweeps up
water and sludge from thebottom for homogenization
inside the tank.

Please see the videoon the website.

Load on the blower becomes
smaller, making it possible togreatly reduce power
consumption.

Aquablaster makes a difference compared toother diffusion pipes! Six features of Aquablaster１■ Comparison of dissolved oxygen concentration trends

Even compared to products of othermanufacturers in this category, thetop level of oxygen dissolution
power is promised.
*Levels of oxygen dissolution efficiency that have been open to the publiccannot be used as indicators in comparison because of the lack of definite
measurement criteria.

２Reduced cost ofelectricity byPressure LossAquablaster with zero pressure loss
has an energy-saving effect which
consumes less electrical power thanother diffusers.

3Reduced sludge
outputOil content
SludgeSludge output is reduced because
SS and oil content are pulverized
into particles small enough formicroorganisms to eat easily.
*Pulverization of sludge is prevented by adjusting the air volume.

After use

Microscopic bubbles spread throughout the water tank

Powerful stirringinside a tank

Sludge on the bottom is swept up
and its accumulation is prevented toeliminate anaerobic areas.
Such a substance as silica and calcium is also
prevented from settling.
