9 inch Disc Diffuser Aerator with ABS Support Part And EPDM Membrane

9 inch Disc Diffuser Aerator with ABS Support Part And EPDM Membrane

                         Product Description                              

The disc diffuser aerator is a kind of aerator developed in 1980s. It has the advantages of small aeration bubble, large gas-liquid area, uniform bubble diffusion, no hole blockage and corrosion resistance. ABS engineering plastic is used as the main body, and EPDM rubber is used as the diaphragm. The diaphragm opening is made by machining. The numerical control opening is used to ensure the quality and accuracy of the hole. When the aerator is aerated with oxygen, four air supply tanks are designed on the main panel, so that the incoming air can be buffered by the check valve and directly sent to the center of the aerator head, so as to ensure that the diaphragm can be opened easily at one time with low resistance. The diaphragm is mechanically assembled with rib anti lock to keep the diaphragm from falling off. When air enters, the micropores on the air distribution membrane expand by themselves to make air pass through.

1. The overall structure of the aerator is scientific and reasonable, with advanced technology and novel design.

The aerator has excellent performance of anti blocking and water-proof body backflow. Under the intermittent operation condition, it is not easy to deposit sludge on the surface of the aeration membrane, which has longer service life and higher oxygen charging efficiency than the flat membrane microporous device, and is also suitable for biological treatment of micro pollution of source water. Features anti blocking and anti backflow.

2. The aerator is in the shape of a spherical crown. Even though the water quality of the aerator is complex, it still operates intermittently, and its surface is not easy to deposit mud. The drilling technology of the diaphragm is unique and advanced, which is inclined through the incision. In addition, a special seal ring is set in the center of the top to effectively prevent the backflow of water.

3. The diaphragm has strong tear resistance. The rubber diaphragm is of spherical crown shape. When it works, the opening force of the eyelet is uniform, the fatigue deformation degree is reduced, the resilience is good, it is not easy to tear, and the service life is long. Uniform air distribution, energy saving and high efficiency. The working surface area of the spherical crown aerator is relatively larger than that of the flat plate, with small bubbles, uniform air distribution, high oxygen charging efficiency and good treatment effect. Especially in the low gas work, it can still play this feature, convenient operation and management. Resistant to aging and corrosion.

4. The spherical cap aeration diaphragm is made of high-quality rubber, and the supporting tray and threaded nozzle are all engineering plastics. These materials have excellent physical and mechanical properties. It has excellent aging resistance, acid, alkali and chemical corrosion resistance. The resistance loss is small.

5. Due to the unique anti blocking and waterproof backflow performance of the aerator, the check valve attached to the flat microporous aeration is omitted, thus reducing the resistance of the aerator. Energy saving.

During installation, the support tray (with G3 / 4 "internal thread airway in the center) shall be installed on the threaded joint at the top of the air distribution pipe. When the spherical crown microporous aerator works, the upper air distribution pipe enters the aeration diaphragm room through the supporting bracket airway.

Under the action of air pressure, the diaphragm is slightly bulged and the eyelet is opened, and micro bubbles with diameter less than 3mm can be produced in water. Stop the air supply, as the pressure between the diaphragm and the tray decreases gradually, as well as the resilience of the water pressure and the diaphragm itself, make the hole gradually closed, and compact the diaphragm on the support tray. Technical performance parameters: aeration size: 215 × 160mm; applicable working air volume: 0.8-0.3m3/h; service area: 0.35-0.6m3/h; oxygen utilization rate: 24-31%; oxygen charging capacity: 0.169-0.244kgo2/h; oxygen charging power efficiency: 6.5-6.8 kgo2 / h; resistance loss of aerator: ≤ 3200pa; arrangement, installation and commissioning of spherical aerator equipment can be supplied in complete set, accessories Including gas distribution pipe, pipe fitting, horizontal regulator, cleaning device, connector, etc.

The vertical layout dimension of the aerator is about 230mm from the surface to the bottom of the tank and 110mm from the air distribution center to the bottom of the tank. It can also be scheduled according to the user's requirements. The air distribution pipe should be connected into a ring network to ensure the uniformity of air distribution in the system. Each group shall be equipped with valves to facilitate the adjustment of air volume. The velocity of air duct is generally 10-15m / s for main pipe and 4-5m / s for branch pipe.
