River oxygenation aerator

Produced by Nanjing Du'an Water Treatment Equipment Co., LtdRiver oxygenation aeratorLong lifespan, less noise, and trouble free operation. A regular centrifugal submersible is a type of submersible that we used to refer to as a centrifugal machine. Centrifugal immersion aerator is a water treatment equipment with a direct coupling structure.

The rotation of the impeller of the water aerator generates centrifugal force, which forms a negative pressure zone. Air is sucked in through the intake pipe, and the mixed air and water are automatically discharged from the outlet through the mixing plate and a good uniform mixture.

River oxygenation aeratorThere are a large number of submersible aerators, and there must be a corresponding difference between different types of products, each with its own shortcomings. Of course, there are also corresponding product advantages.

Firstly, this type of submersible aerator has self positioning, easy installation, uninterrupted layout process operation, and the aeration device can independently move and aerate two mixed functions.

Secondly, the design structure of the centrifugal submersible aerator is compact and does not require the use of an external air source for self-priming function. Its main engine is used for diving operations to reduce surface area and minimize noise.

Another more important point is that this submersible aerator can be directly used in the oxidation pond, saving infrastructure costs. In addition, the chassis of this product can be designed according to user requirements.

River oxygenation aeratorThe mixer is an introduction of German submersible motor sealing technology and a self-developed submersible aerator, which has now applied for a national patentzl002429578。 This machine has multiple functions (high-speed aeration and low-speed stirring), which can be used as an aeration and stirring device in various sewage treatment processes, especially in deep tanks (up to a maximum depth of 20m). Main scope of application:

　　1. Deep water aeration;

　　2. SBR biochemical tank aeration and agitation;

　　3. Nitrification or denitrification biochemical aeration and mixing;

　　4. Sludge aeration and mixing;

　　5. High organic wastewater treatment process.

Characteristics of submerged aerator:

　　1. Compact structure and small area;

　　2. Open structure, unobstructed;

　　3. High transmission efficiency, mixed soft uniform;

　　4. Small gas pressure loss and low energy consumption;

　　5. Adjust the intake volume according to the process requirements;

　　6. The motor protection function is complete, the sealing is reliable, and it is easy to achieve automatic control;

　　7. Installation, maintenance, and upkeep are simple and convenient.

　　River oxygenation aeratorStructure and Process

The deep water aeration mixer consists of a submersible motor, reducer, impeller, mixing chamber, base, and intake pipe.

The impeller of the deep water aeration mixer rotates in the mixing chamber and is sucked in compressed air. Due to the special structure of the impeller and the relative rotation of the mixing chamber, the air is cut into very small bubbles, while the water is sucked in and the shredded air is completely mixed, passing through the liquid mixture in the mixing chamber in the horizontal direction. Therefore, microbubbles are uniformly filled with liquid, increasing the surface contact between gas and liquid, improving the efficiency of the aeration system, forming a large communication area, and creating a highly turbulent gas-liquid jet, greatly improving the oxygen transfer rate and oxygen degree of freedom.
