Overview

Product description: Aeration hose is a new type of aerator developed successfully by introducing West German technology. Thin walls and straight channels greatly reduce aeration resistance losses; The automatic opening and closing of variable holes and narrow slits completely solves the problem of clogging in aerators; The hose is designed with linear aeration to ensure uniform air distribution and create vertical circulation, resulting in more even mixing and agitation; Small bubbles, high oxygen utilization and power efficiency.

Product Details

Structure and characteristics:

1. This product is a flexible tubular aerator made of synthetic fiber reinforced improved plastic material.

2. There are air holes on the surface of the hose circumference, which can aerate and produce water

Microbubbles have a slow rising speed, uniform gas distribution, and high oxygen utilization efficiency.

3. The hose swells during aeration and is flattened by static water pressure when not aerated, which to some extent avoids sludge backflow.

4. The wall thickness of the hose is only 2mm, the airway is short and straight, and the pressure loss is small.

5. The pores are narrow slits with varying widths within a certain range.

6. The inner surface of the hose is very smooth and not easily adhered to biofilms.

7. No air filtration equipment is required, and aeration can be stopped at any time without clogging, regardless of the length of time it is stopped.

8. Easy to assemble, with low requirements for installation flatness. The gas delivery pipe and aeration pipe are integrated at the bottom of the pool, without the need for additional pipeline equipment. The price is lower than other microporous aerators.

9. Good acid and alkali resistance.

10. It can be curled and packaged, with a small size and convenient transportation.

Design reference suggestion:

1. Technical parameter values during design: aeration rate of 3m3/m.h, oxygen utilization rate of 12%.

2. The distance between the hose and the bottom of the pool is generally 300-500mm, and the distance between the hoses is 500mm. It can be designed according to different conditions such as water quality, load removal, and oxygen demand.

3. Within a certain range, multiple aeration hoses (generally not exceeding 10) can be connected to the same air distribution pipe to form a group, controlled by a valve. In order to ensure uniform air supply to all aeration pipes in the group, the diameter of the air distribution pipe should be appropriately enlarged.

4. When using aeration hoses in activated sludge processes, especially in sequencing batch reactor (SBR) treatment units, it is recommended to add sewage measures in the design to allow for the discharge of sludge from the pipes if necessary.
