Crown Type Disc Diffuser Aerator with ABS Support Part With Fine
Bubble
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/silicone 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.
Application
EPDM membrane is suitable for biological wastewater treatment and
conventional industrial wastewater treatment, and the service
temperature is 176 ℃.
The temperature of silicone menbrane is - 65 ℃ - 232 ℃, which is
suitable for wastewater treatment in pulp and paper industry,
petrochemical industry and oil refining process.

Product Features
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.
