Details QSB7.5 submersible jet aerator: QSB7.5 submersible jet aerator main purpose and scope 1. Purpose submersible aerators for wastewater treatment plant aeration tanks, aerated grit chamber, can also be used small sewage treatment plants, industrial wastewater treatment and fishpond oxygen. 2. Features a compact), small footprint, easy installation. 2) In addition to inhale the estuary, the rest into the water, noise. 3) more than the intake air, and more fine bubbles, dissolved oxygen rate. 4) do not need to provide the gas source, eliminating the blower, less investment project. 5) ABS technology with the introduction of Germany, does not clog impeller type, safe, and reliable. 3.QSB7.5 diving jet aeration mechanism and working process manufacturing submersible aerator by submersible sewage pumps, mixing chamber, base, intake manifold and composition. The upper intake manifold for air intake is located above the water, the lower end of the mixing chamber after the power is turned on because of the impeller rotation speed of the impeller outlet water outflow from a negative pressure through the mixing chamber, which air is drawn and mixed with water, the mixture from export out of, the completion of sewage oxygenation. QSB7.5 submersible jet aerator characteristics: QSB submersible aerator using a rotary motor direct drive centrifugal impeller to cause so sucked into the water near the low pressure, while also creating a vacuum at the impeller inlet to suck air in the mix the gas chamber, rapidly excreted by the centrifugal force after mixing the air and water. Due to strong water jets, resulting in an effective convection circulation, leaving the air is divided into many small bubbles. And due to the rising gas bubbles slowly leaving the oxygen dissolved in the water in the atmosphere. Because the bubble is small and can not be counted, its surface area is large, such that the mass of gas per unit of horsepower is higher than other types of aerators.
