The Most Advanced Aerator and Agitator in the World Hanshin Aquarator

The Hanshin Aquarator is the original aerator and agitator and it is also the pinnacle of the technology.
Since the invention of the world’s first, energy conserving aerating/agitatingequipment in 1975,Hanshin has continued to provide technological innovations to pioneer a new future for people and water.
The Hanshin Aquarator is the embodiment of these ideas and technology at their highest levels.

Realization of extremely high energy efficiency

By separating the power s ing air and aeration/
agitation to create rational submerged equipment, energy efficiency is drastically
increased by being able to arbitrarily control both functions at the same time, or
each function separately.

Easy maintenanceEasy maintenance

Due to its simple design, maintenance can be performed on-site. This also
dramatically decreases the time required for maintenance. In addition, because
the Aquarator is simply placed along a guide pipe, water draining is not required
when installing or removing the Aquarator.

Accommodates various processing methods

By separating power sources, the Aquarator can act as a submerged agitator for
both aerobic and anaerobic agitation, as well as accommodating various
processing methods such as aerobic and anaerobic activated sludge process.
Reliable solid-liquid separation in the final sedimentation tank can be performed.
*The Aquarator can accommodate standard activated sludge process, multi-stage
aerobic and anaerobic process, batch-wise activated sludge process, air lift
circulating nitrification/denitrification process, intermittent prolonged aeration
process, as well as deep tanks and modifications to the installed tank.

No cloggingNo clogging

Age related deterioration is eliminated by using HANSHIN ENGINEERING’s
proprietary Air Dispersing Rotor with an air miniaturization mechanism that
doesn’t clog. This provides stable functioning over a long service life.

A submerged aerobic and anaerobic aerator/agitator that accommodates numerous processing methods

The Aquarator can flexibly accommodate numerous processing methods.
Freely choose installation methods depending on the provided environment.
The Aquarator can change shape according to the shape of the tanks and consistently provides the highest
level of performance.

Overall configuration

The Aquarator separates the power sources for the 2 main functions for aeration which are the supplying of air and agitation/aeration. By creating rational submerged equipment for the latter, the energy efficiency of aeration has been greatly increased.

By separating the control factors for the air supply function and the aeration/agitation functions, the Aquarator can act as a submerged agitator for both aerobic and anaerobic agitation, as well as being able to easily select between various processing methods such as standard activated sludge process, aerobic and anaerobic activated sludge process, intermittent prolonged aeration process, batchwise process.

The separation of the control factors (power source) means the Aquarator can easily accommodate changes in water processing conditions and processing methods in an energy efficient manner. Depending on the circumstances and purpose, the unit can use either the air supply function (blower) or the aeration/agitation functions (Aquarator) separately or both controlled arbitrarily to be able to perform appropriate processing even
under heavy loads.

Overall configuration

Transition from traditional aeration equipment

The Aquarator can flexibly accommodate different tank shapes and operational methods for reliable processing.
The Aquarator, which is for both anaerobic and aerobic use can not only act as aeration equipment, but its capabilities also fully shine as an agitator as well. The Aquarator can also be used as reinforcing agitator for other aeration equipment.
The Aquarator can solve various problems such as low levels of DO (Dissolved Oxygen) in the tanks as well as reduced functionality due to accumulation
of sediment and clogging.
