AQUATURBO® AER-AS

Floating surface aerator
AQUATURBO AER-AS

DESCRIPTION

The floating aerator Aquaturbo® AER-AS is an equipment for the aeration and agitation of wastewater.

Its design gives it high performance and very low maintenance, being a unit capable of operating for long periods of time without the need for attention.

APPLICATIONS

Aeration and agitation in tanks and lagoons for urban and industrial wastewater in general.

Cooling in homogenization tanks and biological reactors for waste or process water.

Aeration and agitation in tanks of complicated industries such as poultry, pig and bovine slaughterhouses and chemical industries.

OPERATION

The Aquaturbo® AER-AS works as an open pump sucking in residual water and activated sludge through its suction cone.

Its Screwpeller®, with a patented design, sucks the liquid towards the upper cylindrical cone that diverts the flow transforming it from axial to radial and ensuring that the maximum kinetic energy is transferred to the water surface.

Due to the design of the Screwpeller® the stress on the bearings is very low, so standard bearings can be used. In addition, the Aquaturbo® AER-AS aerator has lower energy consumption in real working conditions compared to other similar systems due to its optimized design and the use of its patented Screwpeller®.

CONSTRUCTIVE CHARACTERISTICS

All AER-AS aerators are equipped with a Screwpeller®.

Equipment completely made of AISI 304 stainless steel as standard, and AISI 316 as an option, in all its submerged parts.

High efficiency IE3 motorization and high-performance design under Aquaturbo® specifications.

Stainless steel floats filled with high density polyurethane.

Construction of the suction cone and stabilization cross adapted to work levels.

Fastening system using stainless steel cables and springs or guide tubes depending on the configuration of the tank and water levels.

ADVANTAGES

A - COMPARED TO LOW-SPEED AERATORS

– Easy installation and maintenance (no structures or bridges are needed for assembly).
– Does not need a geared motor to control the revolutions.
– There is no difference in the efficiency of oxygen transfer in wastewater.
– Does not need deflectors.
– Completely made of AISI 304 stainless steel.
– Float filled with polyurethane foam: cannot sink.
– Standard flotation equipment: No problems with water level differences or vibrations.

B - COMPARED TO COMPETITION HIGH SPEED AERATORS

– It has a unique design that ensures the transfer of maximum kinetic energy to the water. Our Aquaturbo® have a higher oxygen transfer efficiency than other types of equipment.
– The Aquaturbo® cause a flatter and longer flow, in this way the total energy is transmitted in a horizontal movement of water and the diameter of oxygen dispersion is very large.
– The resulting speed induced by our Aquaturbo® high speed floating surface aerators is greater than the resulting speed of our competitors, resulting in a larger contact surface and consequently greater efficiency.
– Thanks to its design, the Aquaturbo® generates a large diameter of high turbulence and induces a strong secondary flow.

C - COMPARED TO FINE BUBBLE AERATION

– Easy installation and maintenance, no soundproofing, bridges, gear motors, etc. are needed.
– The tank does not need to be emptied for maintenance.
– There is no difference in the efficiency of oxygen transfer in wastewater.
– Oxygen transfer efficiency does not deteriorate over time, unlike diffusers.
– Does not get stuck, does not produce layers of biological substance, does not break.
– Does not depend on a blower, nor on its efficiency and maintenance.
– It is not necessary to cover the entire tank floor to ensure complete mixing.
– Water cooling capacity. The diffusers do not have any cooling capacity.
– Greater flexibility if additional aeration is required.
– There is no floating sludge. Aeration by diffusers can cause masses of sludge.
– No possibility of oil leaks.
– No need for pipes, no drainage operations, no maintenance, and repair of leaks.
– There are no replacement costs. Fine bubble diffusers have to be replaced often.

D - COMPARED TO EJECTOR SYSTEMS

– No blower and booster pumps needed, so no noise and no need for soundproofing for the blower.
– Surface aerators cool the wastewater. On the contrary, aeration systems with ejectors heat the wastewater, causing two major disadvantages: a higher respiration rate of the active sludge (therefore, more oxygen is needed), and a lower oxygen saturation level of the water.
No sludge damage due to Screwpeller design. The pump in ejector aeration systems that is continuously pumping activated sludge into and out of the reservoir can cause damage to the sludge.
– There is no possibility of jams. The ejector aeration system can become clogged because the contents of the reservoir are continually being pumped in and out.
– Low cost of installations. Ejector aeration systems have high installation costs.
– Completely manufactured in AISI 304 stainless steel as standard. Float filled with polyurethane, cannot sink.
– Standard flotation equipment: No problems with changes in water level or vibrations.
– Ejector aeration systems are fixed systems, so vibrations (pump, blower) can cause a system breakdown and eventually collapse or break the tank itself.

E - COMPARED TO SUBMERGED AERATORS

– There is no submerged motor.
– Increased efficiency from 20% to 50%. .
– Very good aeration and mixing in large tanks. Unlike the other system where only local mixing and aeration takes place and to achieve a better mix, extension channels are necessary.
– Standard flotation equipment: No problems with changes in water level or vibrations.
– Easy maintenance: submerged bottom aerators maintenance is not so easy. .
– Cooling effect. No cooling effect possible on bottom aerators.
– There is no possibility of jams. Bottom aerators can get clogged and fail.
