1. Product Overview
The disc-type microporous aerator is a new type of aeration device developed in the 1980s. This aeration device has the characteristics of small aeration bubble diameter, small gas-liquid interface diameter, large gas-liquid interface area, uniform bubble diffusion, no pore clogging, and strong corrosion resistance. The Qingshui River sewage oxygenation test was conducted by the School of Environmental Engineering of Tongji University, and has been used by many users for many years with good results (higher utilization rate than rotary mixing aerator, less prone to clogging than corundum aerator, and 40% more processors than perforated aerator). It is especially suitable for urban sewage and large-scale factory expansion and renovation of old pools.
2. Structural Features
The disc-type microporous aerator is designed with a slightly convex arched surface and is made of ABS engineering plastic as the main body. The disc aerator diaphragm has special imported rubber (EPDM) with an anti-adhesion surface and is made through special processing. The opening of the microporous aeration disc diaphragm uses CNC opening imported from Germany to ensure the quality and accuracy of the holes. When the disc aerator is aerated with oxygen, six air supply grooves are designed on the main panel, so that the incoming air is buffered by the check valve and directly sent to the center to ensure that the diaphragm can be opened easily at one time with low resistance. The disc aerator adopts ribbed anti-locking mechanized assembly to ensure that the diaphragm does not fall off. When air is taken in, the micropores on the air distribution film expand by themselves to ensure that air can pass through. When aeration is stopped, the variable micropores on the air distribution membrane are in a closed state. Since the variable micropores of the air distribution membrane expand and contract by themselves, the micropores passing through the disc aerator diaphragm are prevented from being blocked. Secondly, the bottom plate of the disc microporous aerator is equipped with a check valve device to prevent the mixed liquid from entering the gas distribution branch pipe when the pipeline system stops supplying air. This can prevent the mixed liquid from entering the branch pipe and being blocked. The air entering the disc aerator does not require special filtration, and the intermittent aeration is not clogged. It has also made great technical improvements to overcome the common phenomenon in disc aerators that the air distribution film is easy to blow and tear, and the diaphragm cannot be opened or the diaphragm is blocked. These technical reforms enable it to avoid maintenance in long-term operation. The disc aerator is a good product.
