The aeration process is indispensable in any wastewater treatment plant, regardless of type. Organic and inorganic pollutants in wastewater are purified as a result of the digestion of microorganisms. Since this digestion is a natural process, the need for air is inevitable.

The equipment that provides this air support to wastewater is aerators, or in other words are aerators.

The most commonly used types are floating pontoons. aerators, blower-diffuser systems and mixer jet aerators.

Floating Pontoon Aerators: The aerator introduces air into the water by floating over a bridge or buoy. The clogging time is quite long. High oxygen transfer efficiency is aimed by providing air flow from the middle region of the water.

Blower-Diffuser Systems: There are small pores on the bottom and surface of the wastewater tank, with diameters that may vary depending on the character of the wastewater. The air flow rate provided by the blower provides the oxygen requirement of the water through these diffusers.

Mixer Jet Aerators: It is the type generally used in mud units. By means of a mixer, both mixing and aeration of the sludge is ensured. Mixer blades are generally stainless steel.
