Product Description
submersible aerator
QK-QB Submersible Sewage Aerator introducing high-tech from Finland, is a new self-developed submersible type aerator.
Submersible sewage aerator is a essential equipment in aeration basin, it utilize fine or medium bubbles diffuse to provide aeration and mixing to process water, and widely used in many places.
As one of the best mixing type aerator in China, with outstanding advantages:
• Higher oxygen conversion rate
• Fast install, no need to empty aeration tank
• 100% no clogging
• High working efficiency
• Underwater working, noiseless
• Longer life service
How It Works
Working Principle-submersible aerator
The pressured air supplied by blower goes though air pipe and reach to rotor, high speed rotor hit and break pressured air into tiny bubbles.These tiny bubbles and water around are shaped to wave curve by strongly mixing of rotor. The stator channel can ensure the air-water liquid evenly distributed in different shapes of aerator basin, meantime, strong mixing flow by rotor continuously mix the water ,air and activated sludge, which ensures the ideal aeration efficiency.
The negative-pressure while submersible aerator working, lead to self priming , thus it will lower the air pressure ,supplied by blower, normally this pressure just equal to water height. So it is obviously energy-saving than traditional aerator.
Application
Such as :
• Municipal sewage treatment plant
• Industrial wastewater treatment plant
• Paper mill wastewater treatment
• Petroleum industrial wastewater treatment plant
• Chemical industrial wastewater treatment plant
• etc.
Construction
Gear motor; Air inlet pipe; Air outlet channel; Pedestal; Conical impeller; Air supply system; Electric system etc.

1. What is the primary function of the Automatic Heavyduty Submersible Aerator?
The primary function of the Automatic Heavyduty Submersible Aerator is to provide aeration and mixing in wastewater treatment processes, particularly in applications such as municipal sewage treatment and industrial wastewater treatment.
2. How does the submersible aerator work?
The submersible aerator works by using a blower to supply pressured air through an air pipe to a high-speed rotor, which breaks the air into tiny bubbles. These bubbles mix with the water and activated sludge, ensuring effective aeration and mixing.
3. What are the key advantages of using this aerator?
Key advantages include a higher oxygen conversion rate, fast installation without needing to empty the aeration tank, 100% clogging prevention, high working efficiency, noiseless operation underwater, and a longer service life.
4. Where can the submersible aerator be used?
It can be used in various applications, including municipal sewage treatment plants, industrial wastewater treatment plants, paper mill wastewater treatment, petroleum industry wastewater treatment, and chemical industry wastewater treatment.
5. What is the energy efficiency of the submersible aerator?
The submersible aerator is designed to be energy-efficient, as it operates under negative pressure, which reduces the air pressure required from the blower and saves energy compared to traditional aerators.
6. What materials are used in the construction of the aerator?
The construction includes components such as a gear motor, air inlet pipe, air outlet channel, pedestal, conical impeller, air supply system, and electric system.
7. What are the dimensions of the available models?
The aerator is available in various models with different dimensions, including height ranging from 1350 mm to 2500 mm and diameter from 1200 mm to 2610 mm, depending on the model selected.
8. What is the maximum working depth of the aerator?
The maximum working depth for all models is 20 meters.
9. What is the oxygen output capacity of the aerator?
The oxygen output capacity varies by model, ranging from 45 kgO2/h to 390 kgO2/h at a depth of 5 meters.
10. Is installation difficult?
Installation is designed to be fast and straightforward, as it does not require emptying the aeration tank, making it easier for users.
11. How does the aerator prevent clogging?
The aerator features a design that ensures 100% clogging prevention, allowing for uninterrupted operation even in challenging environments.
