The rubber diaphragm tube diffuser is a famous product that has been widely used in sewage treatment plants in famous places around the world for decades. Its reasonable variable hole structure, high efficiency and long service life are unanimously recognized in the market. The structure of polyethylene aeration pipe is the same.
The diffused air uses a high-resilience membrane and unique perforation technology, which allows the diffuser to adjust the size of the micropores according to the air volume. It can automatically close the micropores when the air supply suddenly stops, effectively avoiding active pollution. The phenomenon of mud backflow and micropore clogging can be eliminated to achieve intermittent operation in the true sense.
As a rigid diffuser, the polyethylene aeration pipe cannot automatically close the micropores after the air supply is stopped, which will cause activated sludge backflow. Because its inner and outer surfaces are very smooth, when the system suddenly stops running for a short period of time, the diffuser will not be completely clogged and cannot be used. However, due to the presence of water pressure, some sludge will inevitably remain in the diffuser. Therefore, after a general rigid diffuser stops operating, its pressure drop will increase significantly. After that, the load of the fan will increase significantly, that is, the operating energy consumption will increase significantly. If the fan air volume is frequently adjusted due to changes in water volume or water quality, the polyethylene aeration pipe will be easily blocked, and the corresponding fan energy consumption will increase until the entire aeration system is paralyzed. From the perspective of oxygen transfer, the smaller the diameter of the bubbles released by the diffuser, the better. To fully mix the sewage, the aeration bubbles must not be too small. Practice has proven that the most reasonable bubble diffusion system is that about 80% of the escaped bubbles are less than 2mm in size and about 20% of the escaped bubbles are larger than 2mm. This bubble system can not only provide a high oxygen transfer rate, but also play a sufficient stirring role.
