Microporous aerator is a necessary equipment for sewage aeration and oxygenation. The aeration diaphragm of microporous aerator is made of EPDM and silicone rubber. Microporous aerator is a necessary equipment for air blast aeration and oxygenation. The selection of aeration equipment not only affects the effect of wastewater biochemical treatment, but also affects the occupation, investment and operating cost of sewage treatment plant.

The device has the advantages of small diameter of aeration bubble, small diameter of gas-liquid interface, large area of gas-liquid interface, uniform diffusion of bubble, no hole blockage and strong corrosion resistance. According to the classification of root diaphragm, the silicon rubber diaphragm type micro-porous aerator has the highest cost performance and has been used by many users for many years with good results. It is especially suitable for the new expansion of urban sewage and large factory and the renovation of old aeration tank, and the aeration tank can run intermittently.
