An Air Diffuser is an aeration device installed at the bottom of treatment tanks to introduce compressed air into water. The diffuser converts compressed air into either fine or coarse bubbles, increasing dissolved oxygen (DO) levels necessary for biological wastewater treatment.
Efficient aeration is one of the most important processes in sewage and wastewater treatment plants, accounting for nearly 50–70% of the total energy consumption of an aeration system. Selecting the right diffuser can significantly improve oxygen transfer efficiency while reducing blower power consumption.
