1、 Superiority
The membrane type microporous aerator is the latest type of aeration device developed in the 1980s. This device has small aeration bubbles, a large gas-liquid area, uniform bubble diffusion, no pore blockage, and strong corrosion resistance. But after years of operation, some difficult to solve shortcomings have emerged. For example, problems such as membrane detachment, membrane tearing, membrane failure to open, and sludge entering the bronchi. Therefore, our company's research and development department has cooperated with many domestic and foreign universities and research institutions to absorb international advanced experience and overcome various technical difficulties. We have reformed the membrane aerator and developed a new generation of disc membrane microporous aerator with international advanced level in the 21st century.
2、 Main technical performance
The variable microporous aerator is designed with a slightly raised arch surface, using ABs engineering plastic as the main body. The membrane has a special imported rubber (EPDM) with an anti adhesion surface, which is made through special processing. The membrane holes are made with German imported CNC knives to ensure the quality and accuracy of the holes. The aerator is designed with four air supply slots on the main surface during oxygen aeration, allowing the incoming air to be buffered by check valves and directly sent to the center of the aeration head to ensure that the membrane can be easily opened with low resistance at once. The membrane adopts ribbed locking mechanical assembly to ensure that the membrane never falls off. During air intake, the micro pores on the air film expand and open on their own to ensure the passage of air. When the aeration is stopped, the variable micropores on the air distribution film are in a closed state. Due to the self expansion and contraction of the variable micropores on the air distribution film, the phenomenon of blockage of the micropores passing through the aerator is avoided. Secondly, a check valve device is installed on the bottom of the aerator to prevent the mixed liquid from entering the gas distribution branch pipe when the pipeline system stops supplying gas. This can prevent the mixed liquid from entering the branch pipe and being blocked. The incoming air does not require special filtration, and intermittent aeration does not cause blockages. Significant technological improvements have been made to the commonly occurring phenomena of blown air film tearing, inability to open the membrane, or membrane blockage in variable microporous aerators. These technological reforms have eliminated the need for maintenance during long-term operation, making it an excellent product of the new generation.

5、 Connection method and installation of aeration pipeline
The aeration device consists of a rubber membrane microporous aerator, a gas distribution pipeline, a regulator, connectors, a cleaning device, etc. The gas distribution pipeline is arranged in a circular shape, and the rubber membrane microporous aerator is arranged according to the gas supply volume and pool shape density. The connection between the aerator and the gas distribution pipeline is made of G3/4 thread connection. The base (fixed on the gas distribution pipeline) of the rubber membrane microporous aerator is externally threaded. When installing, first fix the regulator to the bottom of the pool with expansion bolts according to the required size, and then fix the gas distribution pipeline to the regulator. To prevent damage to the aeration device caused by other operations such as welding sparks and heavy objects such as concrete during civil construction, the aerator must be installed before discharging water after civil construction. To prevent air leakage in pipelines and connecting parts, water should be discharged to a depth of about 10cm above the aerator for leakage testing. Air leakage in the connecting part of the ventilation pipeline should be promptly eliminated before formal operation.
