Air enters the aeration tube from the vent hole of the back cover of the microbubble aeration tube. The tube wall of the aeration tube is densely covered with many small pores. The sewage forms many tiny bubbles and causes the turbulence of the water, thus achieving the purpose of dissolving the oxygen in the air into the water.
There are many types of microporous aeration pipes. There are two commonly used aeration pipes. One is a common aeration pipe sintered from coarse porcelain or corundum. This type of pipe wall produces many tiny pores during the sintering process. Its main feature is that it can generate tiny bubbles, the bubble diameter is about 0.1 ~ 0.2mm, the gas and liquid contact area is large, the oxygen utilization rate is high, and generally can reach 20 ~ 25%; its disadvantage is that the air pressure loss is large, and it is easy to be blocked. , The incoming air needs to be filtered and is easily damaged. Once damaged, the oxygen utilization rate will begin to drop rapidly.
The other is a tubular membrane microporous aeration tube. The installation method of this aeration pipe is basically the same as the previous one, but its own structure is very different. It is made of a pipe made of ABS or UPVC as the air distribution pipe, and there are ventilation holes on the pipe wall. , The outer circumference of the air pipe is covered with a diaphragm made of synthetic rubber, and the diaphragm is fixed on the pipe by a metal clip. Use laser and other methods to make evenly distributed holes on the synthetic rubber diaphragm.
During aeration, air enters between the diaphragm and the pipe wall through the vent holes on the pipe wall. Under the action of the compressed air, the diaphragm slightly bulges and the perforations are opened to achieve the purpose of air distribution and diffusion.
