Advantages 
    The diaphragm microporous aerator is the latest aeration device developed in the 1980s. It features small bubble diameter, large gas-liquid interface area, uniform bubble diffusion, no pore clogging, and strong corrosion resistance. Tests conducted by the School of Environmental Engineering at Tongji University in Shanghai and the North China Municipal Engineering Design Institute on oxygen transfer in clean water and wastewater, along with over 50 users' years of successful operation, demonstrate excellent performance (40% energy reduction compared to conventional fixed spiral aerators, diffused aeration devices, and perforated pipe aerators, or a 40% increase in wastewater treatment capacity). It is particularly suitable for new and expanded urban wastewater treatment plants and large factories, as well as the renovation of old aeration tanks, and the aeration tank can operate intermittently.

Aeration Pipeline Connection and Installation
    The aeration system consists of aerators, air distribution pipes, tees, elbows, regulators, connectors, and cleaning devices. The air distribution pipes are typically arranged in a ring layout, with aerator density based on air supply and tank shape. Aerators are connected to the air distribution pipes using G3/4 threaded connections, with the base having internal threads (fixed to the air distribution pipe) and the aerator having external threads. During installation, first secure the regulator to the tank bottom with expansion bolts as required, then fix the air distribution pipe to the regulator using clamps. To prevent damage from other operations such as welding sparks and construction activities like concrete pouring, aerators should be installed after civil works are completed and before filling with water. To check for leaks in pipes and connections, fill the tank with water to a level 10 cm above the aerators and conduct a pressure test. If any leaks are found in the pipe connections, address them promptly before正式 operation.
