What is an Air Diffuser for STP?

An air diffuser for STP is a specialized device designed to disperse compressed air into wastewater in the form of bubbles. These bubbles supply oxygen to aerobic microorganisms, enabling them to decompose organic pollutants effectively.

In sewage treatment plants, air diffusers are installed at the bottom of aeration tanks. When air passes through the diffuser membrane or structure, it breaks into small bubbles that rise slowly, maximizing oxygen transfer efficiency.
