8 inch Disc Diffuser Aerator with ABS Support Part And Silicone 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.
Product Features
1. EPDM Rubber diaphragm
Select imported high-quality rubber raw materials, according to the requirements of aeration conditions, customize the material composition and proportion, excellent physical and chemical properties, effectively prevent the diaphragm from shrinking, hardening and aging, and extend the product life.
2. ABS Plastic support plate
Polypropylene and glass fiber are used, and anti aging additives are also provided. The product has excellent toughness while retaining enough strength. The product is resistant to oxidation, UV, impact, creep and corrosion, with stable and stable performance, strong and durable.
3. Process technology, professional and reliable
(1) Professional membrane surface treatment technology, special drilling technology, to ensure smooth surface, small pores, products are not easy to scale, small bubbles, uniform air distribution, effectively reduce the shear damage of bubbles to activated sludge particles, and improve the biochemical activity of the system.
(2) The rubber diaphragm production adopts the molding process to ensure the uniform specific gravity of the diaphragm, multi-directional tear resistance and high tear strength.
(3) Mechanical assembly production line, with hot-melt welding instead of adhesive process, to ensure adequate supply, product quality uniformity, stability and reliability, highly repeatable.
(4) Dust free production workshop, to ensure that the goods are free of impurities, to ensure that the product is stable and reliable.

Installation
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.
