QSB type aerobic biological treatment? Jet aerators are used for aeration tanks, aeration sedimentation tanks, pre aeration tanks, aerobic nitrification tanks, aeration and oxygenation mixing in various biochemical treatment processes of sewage treatment projects, as well as oxygenation in aquaculture ponds.

How to choose a submersible jet aerator? It is recommended to consider five aspects, including liquid delivery volume, head, liquid properties, pipeline layout, and operating conditions.

1. Flow rate is one of the important performance data for selecting jet aerators, which directly affects the production and transportation capacity of the entire device. If the design process can calculate the normal, minimum, and maximum flow rates of the centrifugal aerator. When choosing a centrifugal aerator, the maximum flow rate should be taken as the basis, while considering normal flow rate. When there is no maximum flow rate, 1.1 times the normal flow rate is usually taken as the maximum flow rate.

2. Head is another important performance data for selecting a jet aerator, and generally needs to be selected by enlarging the margin by 5% to 10% before selecting the head.

3. The properties of liquids include the name of the liquid medium, physical properties, chemical properties, and other properties. Physical properties include temperature c, density d, viscosity u, diameter of solid particles in the medium, and gas content. This involves the head of the system, calculation of effective cavitation allowance, and appropriate pump type. Chemical properties mainly refer to the chemical corrosiveness and toxicity of the liquid medium, which are important criteria for selecting pump materials and choosing the type of shaft seal.

4. The pipeline layout conditions refer to the height, distance, and direction of liquid delivery, as well as data such as the lowest liquid level on the suction side and the highest liquid level on the discharge side, as well as pipeline specifications and their lengths, materials, pipe fittings specifications, quantities, etc., in order to calculate the comb head and verify the cavitation allowance.

5. There are many operating conditions, such as the operation of liquid T, saturation vapor force P, suction side pressure PS(), discharge side container pressure PZ, altitude, environmental temperature, whether the operation is intermittent or continuous, and whether the pump position is fixed or movable.

Product Introduction: Kaipude Mobile Installation QSB3.0 Submersible Aerator Inlet Air Volume

Aerobic biological treatment jet aerator is a wastewater device that aerates the aeration tank, and is a type of aeration device in the wastewater activated sludge biological treatment system. The mixture of mud and water is pumped into the nozzle of the jet aerator by a water pump and sprayed out at high speed. In the jet aerator, the oxygen transfer process is achieved by mixing compressed air (or air directly sucked in) with the mud water mixture around the nozzle of the jet aerator and vigorously stirring it in the roaring tube. The bubbles are crushed into mist, and then in the diffusion tube, due to the velocity head becoming the pressure head, the fine bubbles are further compressed, and oxygen is quickly transferred to the mixture, thereby strengthening the oxygen transfer process. The oxygen transfer efficiency can be improved to over 30-35%.

QSB type aerobic biological treatment? Jet aerators are used in aeration tanks and aeration sedimentation tanks of sewage treatment plants to oxygenate and mix the mixed liquid of sewage sludge, as well as to perform biochemical treatment or oxygenation in aquaculture ponds. The intake volume is 10-100 cubic meters per hour, the oxygenation capacity is 0.35-8.20 kilograms of oxygen per hour, and the motor power is 0.75-22KW.

Working Principle:

Aerobic biological treatment? The jet aerator generates a high-speed water flow through the nozzle generated by the submersible pump, forming negative pressure air around the nozzle. After mixing with the water flow in the mixing chamber, a water gas mixture flow is generated in the horn shaped diffusion tube, which is sprayed out at high speed. The water flow carrying many bubbles vortices and stirs in a larger area and depth of water to complete aeration. And its shaft power does not change with the depth of submergence, and the intake volume can be adjusted. Because of this, submersible jet aerators can be applied in pools with significant changes in water level.

Aerobic biological treatment? The jet aerator, due to the water jet *, creates effective water circulation, causing the air to be sheared into a large number of tiny bubbles. Greatly increasing its surface area, and due to the slow rise of bubbles, a large amount of oxygen in the air dissolves in water, making the power efficiency of this machine superior to other types of aerators.
