Precautions to use a transparent PU duct hose
Introduction of Aeration Hose
The aeration hose is a new type of tubular rubber aerator developed by our company. This product is mainly used for aeration of urban sewage and organic industrial wastewater treatment systems. It has a simple structure, high oxygen utilization rate, reliable performance, and difficult air holes. Features such as clogging, non-irrigated sewage, uniform circumferential stress, long life, convenient installation and maintenance, and low system price. This product has been relying on imports for a long time. Our company has conducted in-depth research on it to make its performance reach the level of similar international products, which can save a lot of foreign exchange for the country and promote China’s research in the field of microporous aerators. .
Aeration Hose Product Structure:
1. The aeration hose uses EPDM, which has the characteristics of heat resistance, ozone resistance, acid and alkali resistance, and good chemical stability. Compared with ordinary aeration hoses, its service life can be greatly improved.
2. The air hole of the aeration hose is a long hole in the shape of a letter, which makes it have good stretchability and instantaneous closing. During the aeration, the micro-bubbles with a diameter less than 3mm can be released to obtain higher oxygen utilization rate. The utilization rate is 35 to 42%.
3. The support is hollow and filled with water, which greatly reduces the buoyancy of the aeration system in water.
4. The air guide groove is used to make the air distribution inside the aerator quickly and evenly, so that the aeration hose is evenly stressed, the life of the aeration hose and the uniformity of the released bubbles are improved, and the aeration effect is improved The groove is a narrow groove, and the aeration hole is not opened in the rubber membrane tube area. When the air supply is stopped, the rubber membrane is closely attached to the air guide groove, thereby preventing the backwash of sewage.
