I. Product Overview:

Disk-type microporous aeration devices are a new type of aeration equipment developed in the 1980s. These devices feature small bubble diameter, small gas-liquid interface diameter, large gas-liquid interface area, even bubble diffusion, no occurrence of pore clogging, and strong corrosion resistance. They have undergone oxygenation tests for wastewater in the Qinghe River by the Environmental Engineering College of Tongji University and have been used effectively by multiple users over many years (more efficient than mixed aeration blowers, less prone to clogging than alumina aeration blowers, and increase processing capacity by 40% compared to perforated aeration blowers). Particularly suitable for new construction and expansion of urban wastewater treatment plants and the renovation of old ponds.

II. Structural Features

The disc-type micro-porous aeration diffusers are designed with a slightly arched surface, mainly made of ABS engineering plastic. The diaphragm of the disc-type aeration diffuser features a special imported rubber (EPDM) for anti-adhesive surfaces, precision-machined for quality and accuracy. The micro-porous aeration disc diaphragm features German-imported CNC punching, ensuring the quality and precision of the holes. During oxygen aeration, the main disc surface is designed with six air supply channels, allowing the incoming air to pass through a stop-check valve buffer and directly to the center for a one-time, low-resistance, easy opening of the diaphragm. The disc-type aeration diffuser utilizes a threaded reverse lock mechanical assembly to ensure the diaphragm does not fall off. During intake, the micro-porous gas distribution membrane inflates automatically, ensuring air passage. Upon stopping aeration, the variable micro-pores on the gas distribution membrane are in a sealed state, preventing blockage in the micro-pores of the disc-type aeration diffuser diaphragm. Additionally, a check valve device is installed on the bottom plate of the disc-type micro-porous aeration diffuser, preventing mixed fluid from entering the gas distribution branch when the pipeline system stops supplying air, thus avoiding blockage due to mixed fluid entering the branch. The air entering the disc-type aeration diffuser does not require special filtration, and intermittent aeration does not cause blockage. Significant technical improvements have been made to address the common issue of the gas distribution film being easily blown apart, or the diaphragm not opening or being blocked in disc-type aeration diffusers. These technical reforms eliminate the need for maintenance over the long term, making the disc-type aeration diffuser an excellent product.

Standard model

One-way check valves often adhere to rubber over time, leading to backflow of waste water and sludge into the pipeline, affecting the lifespan of the fan and uneven aeration. The thin thread edge is prone to breaking, impacting service life. The aerator connector is flat, and the rubber ring is exposed on the surface. During installation and tightening, the rubber ring is very susceptible to deformation, causing leaks.

AiQin Optimized

Cross-type check valve, after excellent modification, the valve operates freely with excellent check performance, effectively preventing sludge and wastewater backflow, less prone to clogging, and uniform aeration. The threaded edge is thickened, thereby increasing the service life. The aeration nozzle indentation is optimized, completely enclosing the rubber ring to prevent deformation and air leakage of the rubber ring.
