Aquarator®

There has been a need in recent years to reduce construction costs for flood control and irrigation-related facilities. Changing the wire drum type switchgear to a rack type, has made it possible to save on space and maintenance, and reduce costs.

Aquarator®—The Underwater Mechanical Aerator and Agitator

Ever since inventing the country's first energy-saving aerator and agitator in 1975, Hanshin Engineering has continued to innovate to pioneer a new future for people and water. Consistently embodying this idea and technology in the best possible way is the Hanshin Aquarator®.
The Aquarator® has raised the bar in terms of Japanese aerators and agitators in all kinds of fields.
A technology that continues to evolve ahead of the times with timeless, unchanged ideas.
This fact is borne out in the Hanshin Aquarator®.

The Aquarator® has raised the bar in terms of Japanese aerators and agitators in all kinds of fields.
A technology that continues to evolve ahead of the times with timeless, unchanged ideas.
This fact is borne out in the Hanshin Aquarator®.
By separating the power sources for the air supply and the aeration/agitation functions, the Aquarator® allows for easy tracking of load fluctuations. This helps to save energy, significantly reducing water treatment costs.

Far and wide aeration with oblique discharge. Increased discharge output with petal-shaped segmentation. Free from clogging. High air miniaturization with proprietary technology

The Aquarator® greatly increases aeration energy efficiency through the separation of the power sources for the two main aeration functions, that of supplying the air and agitation/aeration, to become an efficient underwater apparatus for the function of agitation/aeration. (Ministry of Construction (now the Ministry of Land, Infrastructure, Transport and Tourism) Technology Assessment No. 81102)

By separating the elements that control air supply and the function of aeration/agitation, the Aquarator® can be used as an underwater agitator for both aerobic and anaerobic agitation. In addition to the standard activated sludge method, it is easy to choose between various treatment methods, including aerobic and anaerobic activated sludge, intermittent aeration, and batch.

The separation of control (power source) means the Aquarator® can easily accommodate fluctuations in water treatment conditions and changes in treatment methods in an energy efficient manner.

Depending on the situation and purpose, the unit can use the air supply function (blower) or the aeration/agitation function (Aquarator®) either controlled separately or both together at will. This means suitable follow-up treatment can be carried out especially with heavy load fluctuations.

Meeting a Variety of Demands at a High Level

A shift away from traditional aerators

The Aquarator® can flexibly accommodate different tank shapes and operational methods, and can handle treatment reliably.
The Aquarator®, for both aerobic and anaerobic use, demonstrates its performance not only as an aerator, but also as an underwater agitator.
It can also be used as auxiliary agitator for other aeration equipment.
The Aquarator® can solve a variety of problems, including low concentrations of dissolved oxygen (DO) in the tank, sediment build-up, and reduced functionality due to clogging.
