Other Products

1. This product is a flexible tubular aerator made of chemically reinforced modified plastic material.
2. The entire circumference of the hose is perforated with air holes, enabling aeration. It produces medium and fine bubbles in water, with slow bubble rise speed, uniform air distribution, and high oxygen utilization rate.
3. The hose expands during aeration and collapses under hydrostatic pressure when not aerating, which to some extent prevents sludge backflow.

4. The hose wall thickness is only 2mm, with short and straight air channels, resulting in low air pressure loss.
5. The air holes are elongated narrow slits, with variable width within a certain range.
6. The inner surface of the hose is very smooth, making it difficult for biofilm to adhere.
7. No air filtration equipment is required. Aeration can be stopped at any time, and regardless of the duration, it will not clog.
8. Easy assembly with low flatness requirements for installation. The air supply pipe and aeration hose are integrated at the bottom of the tank, eliminating the need for additional piping equipment. The price is lower than other microporous aerators.
9. Good resistance to acids and alkalis.
10. Can be coiled for packaging, with small volume, convenient for packaging and transportation.

Design Reference Suggestions:
1. Recommended technical parameter values for design: aeration capacity 3 m3/m·h, oxygen utilization rate 12%.
2. The distance from the hose to the tank bottom is generally 300–500 mm, with hose spacing of 500 mm. This can be designed based on water quality, removal load, and oxygen demand.
3. Within a certain range, multiple aeration hoses (generally no more than 10) can be connected to the same air distribution pipe as a group, controlled by one valve. To ensure uniform air supply for all hoses in the group, consider appropriately increasing the diameter of the air distribution pipe.
4. When using aeration hoses in activated sludge processes, especially in Sequencing Batch Reactor (SBR) treatment systems, it is recommended to include sludge discharge measures in the design to allow for the discharge of sludge from the pipes when necessary.
