concave aerator

concave aeratorIt is a kind of high-efficiency equipment used for sewage treatment and water body aeration, which generates negative pressure above the water surface through the high-speed rotation of the impeller, which draws air into the water and forms a large number of fine bubbles to realize the dissolution and diffusion of oxygen. This kind of equipment is usually used in the fields of sewage treatment, industrial waste water treatment, river and lake restoration, etc. It can improve the dissolved oxygen content in the water and enhance the self-purification ability of the water body.

 

Working Principle of Swirl Aerator

The eddy-concave aerator utilizes the vortex and negative pressure generated on the water surface by the high-speed rotation of the impeller to draw air into the water body. Air through the gas-liquid mixing, by the high-speed rotation of the impeller broken into a large number of tiny bubbles, these bubbles in the water during the rise with the water in full contact with the water, so that the oxygen in the air effectively transfer to the water body.

 

Work steps:

Impeller rotation to form a vortex: the motor drives the impeller to rotate at high speed, the impeller forms a negative pressure above the water surface, which draws in air and pushes the water body to form a vortex.

Gas-liquid mixing: after the air enters the water body through negative pressure, the air bubbles are broken into fine bubbles and evenly distributed in the water through the churning action of the impeller.

Bubble diffusion: tiny bubbles rise slowly in the water, increasing the dissolved oxygen content in the water, and the oxygen mixes well with the water.

Water circulation: the rotation of the impeller also promotes the flow of water, forming micro-circulation of the water body, preventing localized oxygen deficiency and stratification of the water body.

 

Structural Composition of Swirl Aerator

Motor:

Vortex aerators are powered by a motor that rotates the impeller. The motor usually has a waterproof and corrosion-resistant design for use in long-term water environments.

Impeller:

The impeller is the core component of the volute aerator and is usually made of corrosion-resistant materials. It not only draws in air when rotating at high speed, but also generates a strong water flow to promote gas-liquid mixing in the water.

Suction piping:

The suction pipe connects the air to the impeller area and draws air from outside the unit into the water column through the negative pressure generated by the impeller.

Floating platform or stand:

Eddy concave aerators are usually installed on floating platforms or fixed brackets to facilitate the equipment to float on the water surface or fixed in the center of the water body to ensure stable operation of the equipment.

Protective netting or grating:

In order to prevent debris or large floating objects in the water from entering the impeller area, a protective net or grille is usually installed around the impeller to ensure the safe operation of the equipment.

 

Characteristics of the swirl aerator

Efficient aeration:

Because the impeller can break the air into very fine bubbles, the eddy-concave aerator has a high oxygen transfer efficiency. The smaller the bubbles, the larger the contact area with the water, the easier the oxygen is dissolved and the better the aeration effect.

The water body is highly mobile:

The eddy-cove aerator not only provides oxygen, but also produces a stronger water flow, which promotes water circulation and prevents localized stagnant areas or uneven distribution of oxygen in the water body.

Energy efficient:

Compared with traditional aeration equipment, the concave aeration machine can provide efficient oxygen transfer and water agitation with lower energy consumption, which is suitable for aeration of large or deep water bodies.

Simple structure and easy maintenance:

Eddy concave aerator structure is relatively simple and easy to maintain. Impeller components are usually made of corrosion-resistant materials, durability, routine maintenance and cleaning is also relatively simple.

Adaptable:

The equipment is suitable for a variety of water quality conditions, including highly polluted and suspended water bodies. It is able to adapt to complex environments in wastewater treatment and has good anti-clogging performance.

 

Application Areas of Eddy Aerators

Sewage Treatment:

In wastewater treatment plants, eddy-dove aerators are commonly used in aeration tanks, biochemical tanks and other facilities to provide efficient oxygen supplementation, promote microbial activity and accelerate the decomposition of organic matter.

Industrial wastewater treatment:

For some industrial wastewater treatment projects, concave aerators can effectively enhance the oxygen content of wastewater and accelerate the degradation of organic and inorganic pollutants in wastewater.

River and lake management:

In the management of natural water bodies such as rivers and lakes, the eddy-concave aerator improves the self-purification ability of the water body by increasing the amount of dissolved oxygen in the water body, helps to control the eutrophication of the water body, and prevents the overgrowth of algae.

Aquaculture:

Eddy concave aerator is also widely used in aquaculture, which can provide sufficient dissolved oxygen for fish ponds and breeding ponds to prevent the water body from lack of oxygen and improve the yield and quality of aquaculture.

Ecological restoration:

In the ecological restoration of lakes, wetlands and artificial water bodies, the eddy-concave aerator improves water quality and water body ecology through the dual role of aeration and water flow promotion.

 

Advantages of swirl aerators

Good aeration and high dissolved oxygen rate:

The vortex formed by the impeller can produce a large number of fine bubbles, these bubbles rise slowly and have a large contact surface, which can significantly increase the dissolved oxygen content in the water.

Simple operation and high degree of automation:

With a highly automated design, the Vortex Aerator is very easy to install and operate, and can be adapted to most aeration needs.

Stable operation and strong anti-clogging ability:

The design of the Vortex Aerator prevents the equipment from clogging due to debris, while the equipment operates stably and is suitable for complex water environments.

Energy efficient and environmentally friendly:

Eddy concave aerator is excellent in terms of energy consumption, can get ideal aeration effect with low energy consumption, suitable for aeration and treatment of large water bodies.

 

Selection and Installation of Swirl Aerators

Selection is based on water conditions:

When choosing the right eddy-cove aerator, you need to decide the model and power of the equipment according to the area of the water body, depth, pollution level and other factors.

Mounting Location:

Vortex aerators are usually installed in the center of an aeration tank or body of water to ensure that air is spread evenly to all areas of the body of water while preventing the equipment from coming into contact with sediments at the bottom of the body of water.

Maintenance:

Regularly check the impeller, suction piping and other components, and promptly clean up any debris that may be clogged to ensure the long-term and efficient operation of the equipment.

Eddy concave aerator is a kind of high-efficiency and energy-saving water body aeration equipment, which utilizes the vortex and negative pressure generated by the rotation of the impeller to draw air into the water and form a large number of fine bubbles, which significantly improves the dissolved oxygen content of the water body and promotes the circulation of the water body. It is suitable for sewage treatment, industrial wastewater treatment, river and lake management and many other fields, with high efficiency oxygen transfer capacity, good water body circulation effect, as well as energy saving and environmental protection advantages.
