Submersible jet aerator is used to treat and purify sewage by aerating sewage channels. Aeration, as an important process in the aerobic biochemical treatment system for sewage, is used to oxygenate the reactor, ensuring the dissolved oxygen required for microbial biochemical reactions, and maintaining sufficient mixing of microorganisms, substrates, and dissolved oxygen in the reactor, namely mud, water, and gas, providing favorable biochemical reaction conditions for microbial degradation of organic matter. At the same time, aeration is also the most expensive process in the aerobic biochemical treatment system for sewage. The power consumption of aeration and oxygenation generally accounts for 60% to 70% of the total power consumption. Therefore, selecting aeration devices with low energy consumption and low cost is of great significance. Nowadays, with the continuous improvement of process technology, in order to save various costs during the operation of such equipment, solar aerators have been put into use. The use of solar energy can greatly reduce the huge electricity costs incurred due to power functions. The commonly used aeration methods for aerators are:

1. Blower aeration:

Use a blower with a certain air volume and pressure to connect the conveying pipeline, and force air into the sewage tank through a microporous air diffuser (or microporous air diffuser), so that the sewage in the tank can fully contact with the air.

Characteristics of blower aeration:

1) Has a certain amount of airflow. The purpose of aeration is to increase sufficient dissolved oxygen in water or liquid to meet the oxygen demand of aerobic organisms.

(2) Having sufficient pressure. The aeration process of a blower is the transfer of molecular weight between gas and liquid. In order to fully diffuse and contact the gas in the liquid and prevent suspended solids from sinking, the aeration fan must be able to generate sufficient pressure.

The main application areas of blower aeration are: (1) aquaculture blower aeration; (2) Water treatment with air blowing and aeration.

2. Surface aeration:

It is a method of using a motor to directly drive an axial flow impeller, which sprays wastewater from a conduit through a water guide plate and forms a thin (or droplet shaped) water curtain. During flight, it comes into contact with air to form water droplets, which collide with the liquid surface when falling. The liquid surface produces turbulence and a large number of bubbles, increasing the oxygen content in the water. It can suck up the water at the bottom of the pool and send it out from above, forming a circulating water flow with stirring effect. It is suitable for aeration of domestic sewage, agricultural and animal husbandry oxygen supply, and various other industrial sewage.

3. Submersible jet aeration:

A dedicated water pump for aeration design, consisting of an intake duct, nozzle seat, mixing chamber, and diffusion pipe. The water flows into the mixing chamber at high speed through the nozzle seat connected to the pump outlet, and the air is guided to the mixing chamber by the intake duct and combined with the water flow before being discharged through the diffusion pipe. Also known as jet aerator.

Characteristics and Applications of Submersible Jet Aeration:

The deep water self-priming submersible jet aerator agitates and oxygenates the water body simultaneously, with fine bubbles that can achieve high oxygen transfer rates and have the advantage of unobstructed impellers. The strong unidirectional liquid flow creates effective convective circulation, and the motor load changes very little with the water level, making it more suitable for application in pools with large water level changes. The maximum diving aeration depth can reach 10m without the need for compressed air. Low cost, easy to install and maintain.

4. Submerged aeration:

The use of a motor to directly drive the rotation of the impeller to generate centrifugal force, causing low pressure in the vicinity to be sucked into the water flow. At the same time, a vacuum is also created at the inlet of the impeller to suck in air. In the mixing chamber, this air mixes with water and is rapidly discharged by centrifugal force, which is called a submerged aerator. Due to the strong water jet, it creates effective convective circulation, which divides the air into numerous small bubbles. The bubbles rise slowly, allowing oxygen from the atmosphere to dissolve into the water. The bubbles are uniform and have a large surface area, making their efficiency much higher than other types of aeration equipment.

Characteristics of Jet Submersible Aeration:

1. Unique mixing chamber design, with a large intake of air and uniform mixing with water, producing fine and numerous bubbles with high dissolved oxygen rate.

2. The impeller generates pressure through the nozzle orifice to produce strong water flow mixed with air and sprayed, resulting in high efficiency of oxygen circulation in the water and achieving good stirring effect, which can maintain the necessary flow rate for the floating of activated sludge.

3. This unit is designed for underwater operation with low rotation speed and low noise; The onshore air intake duct can be equipped with silencing devices, and no other silencing room equipment is required to reduce costs.

4. There are two options: automatic detachment device and non attached detachment device, which are easy to install and maintain, saving operating costs.

5. Widely used in industrial wastewater treatment, animal husbandry drainage treatment, general sewage aeration engineering, aeration tanks for factory drainage facilities using activated sludge process, can be used alone or in combination.
