Variable orifice Aeration hose
1. The product is a flexible tubular aerator with chemical fiber reinforced plastic.
2. Peripheral surface of the hose has a stomatal, can be aeration, in the water, microbubbles, air bubbles rise slowly, uniform distribution, high oxygen utilization.
3. Hose in the aeration when the bulging in the non-aeration by the hydrostatic pressure was flattened, to a certain extent, to avoid the sludge pouring.
4. The wall thickness of the hose is only 2mm, the airway is short and straight, the pressure loss is small.
5. Stomatal elongated slits, width within a certain range of variable.
6. The inner surface of the hose is very smooth, not easy to fix biofilm.
7. Do not need air filtration equipment, at any time to stop the aeration, stop the aeration time regardless of the length will not be blocked.
8. Easy assembly, installation flatness requirements are low, in the bottom of the gas pipe and aerator pipe combined, without additional pipeline equipment, the price is lower than other microporous aerator.
9. Good acid and alkali resistance.
10. Can be crimped packaging, small size, packaging and transportation convenience

Design Reference:
1. Design time technical parameters: aeration rate of 3m3 / mh, oxygen utilization rate of 12%.
2. Hose from the bottom of the pool is generally 300-500mm is appropriate, the hose spacing of 500mm, according to the water quality, remove the load, oxygen demand for different design.
3. In a certain range, a number of Aeration hose (generally not more than 10) can be connected with the same air distribution pipe into a group, controlled by a valve, so that all the aerator pipe gas supply uniform, to be considered The pipe diameter of the air distribution pipe should be properly enlarged.
4. If aeration hose is used in the activated sludge process, especially the Sequencing Batch Activated Sludge Process (SBR) treatment unit, it is advisable to increase the effluent measures in the design to allow the sludge to be discharged if necessary.
