4、效果。The submerged aerator uses the following method to oxygenate and mix the wastewater and sludge quickly and efficiently.Renewal of water surface: As the water is sucked into and ejected from the aerator, an efficient vertical circulation is created. This circulation brings oxygen-lacking wastewate

5、r from the bottom to the top, continuously renewing the water surface. The large surface area results in fast and efficient oxygenation of the wastewater.Water jump: Under the powerful pushing force of the impeller, water sprays from the flange in the form of water curtain and forms water jump which

6、 absorbs large amounts of oxygen from the air.Low pressure area: A negative pressure area is produced when the wastewater is flowing through the cone-shaped guide duct inside the impeller. Air is absorbed from the air intake. So the aeration efficiency is further enhanced, while the power consumptio

7、n is reduced.The suction, spraying and spinning action of the aerator creates a helical circulation within the tank. Water at the bottom is constantly brought up to the surface and exposed to the air. Wastewater and sludge are mixed thoroughly. Aerobic bacteria have a plentiful supply of oxygen, thu
