Product Details

ASPIRO


Proven & robust range of aspirating aerator mixers. Subsurface action means quiet operation and excellent directional mixing capabilities in all weathers, and best use of available volumes leading to better treatment outcomes.

The ASPIROis a surface mounted self-aspirating propeller type aerator that draws atmospheric air below the water surface and transfers it via a hollow induction shaft into a highly mixed horizontal water stream not unlike the wake of a boat. This efficiently creates fine bubbles and mixes air and water into any lagoon, tank or other basin that requires it.

Mixing Capabilities

The aspirator aerator is arguably the best mixing aerator available in the world. It can be used alone or in multiples, or in combination with other types of aerators to provide optimal efficiencies for particular applications.

Multiple ASPIRO units can completely or partially mix very large volumes of water at lowest installed power, and provide excellent turndown capabilities.

Treatment Efficiences

This means that the power put into your ASPIRO equipment ensures oxygen distribution throughout even the largest basins – something many other types of aerators fall short on. This results in better treatability of water or wastewater at lower installed power by more effective use of available volume in the treatment plant.

There is little benefit in installing what appears on paper to be an extremely efficient aerator that, in the end, only affects one small portion of your plant and leaves large volumes un-aerated and unmixed.

Odor Control

The ASPIRO aerator is particularly useful where there are high strength wastes and odor concerns. It’s subsurface action negates the possibility of splashing and associated vapor born odors common to other surface aerators.

Flexibility of Installation

The ASPIRO ranges from 2 HP to 100 HP and can be mounted on floats, fixed to a bridge or wall etc. ASPIRO can also be easily installed in fluctuating water level situations.

Options such as stainless steel flotation assemblies, work platforms (on larger units), anchoring and cabling information are all available on request.

Multiple small units can be installed to create an oxygenated ‘odor cap’ on very large and deep basins at very low required power, or conversely can aerate and circulate very shallow basins where other types of aeration cannot be used.

Larger multiple unit installations can suspend the heaviest solids loads in the deepest basins.

Low Noise

The ASPIRO is also arguably the quietest surface aerator available today as aerating and mixing action takes place below the water’s surface in all cases – i.e. no splashing noise. There is also no gearbox, so no low frequency noises associated with reduction drives common to many other units.

Maintenance

Maintenance on the ASPIRO is extremely simple and can usually be carried out with little downtime experienced.

Australian Made - World Class

The entire ASPIRO range is designed and manufactured wholly within Australia with local parts support - and has been exported all over the world. There are now some thousands of units installed.

ASPIRO PLUS


All the features of ASPIRO with the addition of a separate blower to both boost aeration efficiency and also offer a non-aeration mixing mode only for intermittent treatment. These units offer ultimate flexibility in the treatment of municipal, industrial and hazardous applications.

ASPIRO PLUS is the latest development of the PCPL ASPIRO unit. It arises from experimentation with many different propeller discharge head assemblies coupled with assisted positive airflow through the aspirator shaft into the water provided by a regenerative blower connected into the housing of the aerator which is otherwise sealed from the atmosphere.

The ASPIRO PLUS supplies air below the water surface and transfers it into a highly mixed horizontal water stream not unlike the wake of a boat. This efficiently mixes air and water into the lagoon, tank or other basin that requires it.

The development of the ASPIRO PLUS provides higher oxygenation efficiencies than standard ASPIRO units, and also a greater level of control in your plant through the capability to aerate and mix, or to mix alone by turning air blowers off. This is a great advantage to batch operated plants and allows for nitrification and denitrification using the one unit.

Mixing Capabilities

The ASPIROrange is amongst the best of mixing aerators available worldwide, and as the ASPIRO PLUS, now offers higher oxygen transfer rates competitive with any type of surface aeration system. It can be used alone or in combination with other types of aerators to provide optimal efficiencies.

Multiple ASPIRO PLUS units can completely or partially mix very large volumes of water at lowest installed power, and provide excellent turndown capabilities.

Even Higher Treatment Efficiencies

This means that the power put into your super-efficient ASPIRO PLUS equipment ensures oxygen distribution throughout even the largest basins – something many other types of aerators fall short on. This results in better treatability of water or wastewater at lower installed power by more effective use of available volume in the treatment plant.

There is little benefit in installing what appears on paper to be an extremely efficient aerator that, in the end, only affects one small portion of your plant and leaves large volumes un-aerated and unmixed.

Odor Control

The ASPIRO PLUS aerator is extremely valuable where there are odor problems as it’s subsurface action negates the possibility of splashing and associated vapor born odors common to other surface aerators.

Low Noise

The ASPIRO PLUS is also very quiet in operation compared to most surface aerators available today. It’s aerating and mixing action takes place below the water’s surface in all cases. There is also no low frequency noise associated with reduction gearboxes common to many other surface aerators.

Intermittent System Operation - Nitrification/Denitrification

The ASPIRO PLUS is ideally suited to intermittently operated treatment systems, especially those used for biological nutrient removal (nitrification/denitrification).

The key feature of the ASPIRO PLUS is that the air provided by the regenerative blower situated on the aerator assembly can be cycled ‘ON’ & ‘OFF’ as required without compromising mixing capabilities of the unit.

Thus the ASPIRO PLUS can mix and aerate during aeration cycles in an intermittent system, and can then easily make the change to mixer alone for anoxic cycles of the system.

This of course negates the need for extra mixing power in such systems, which results directly in cost savings

Added Control

Both ASPIRO and ASPIRO PLUS can be further controlled via oxygen measurement systems and/or variable frequency drives to give the end-user ultimate management of their aeration system. Greater efficiency at lesser cost is the end result.

Maintenance

Maintenance on the ASPIRO PLUS is extremely simple and can usually be carried out with little downtime experienced.
