The aeration process used in tubular aerators is a method of bringing air into contact with water. The purpose is to dissolve oxygen in the air or to exhale unwanted gases and volatiles from the water into the air. All aeration equipment should meet certain functions, and tube aerators are no exception.

Tubular aerators must be capable of producing and maintaining effective gas-water contact and maintaining a certain dissolved oxygen concentration in the water in the event that biooxidation continues to consume oxygen; and produces sufficient mixing and water in the aeration zone Circulating flow; of course, it is also necessary to maintain a sufficient velocity of the liquid to suspend the biological solids in the water.

In addition, tubular aerators use different methods for different concentrations of wastewater. When the method of using the low-concentration sewage is an aerobic method, such as ethylene plant sewage, the aerobic microorganisms present in the activated sludge are necessary to have an effect in the presence of oxygen.

The method of using the tubular aerator in the disposal of sludge and higher concentration sewage is the anaerobic method. It is an artificial strengthening method for self-purification of water bodies, and a method for removing organic matter in sewage depending on the main body of the activated sludge mission. The dissolved oxygen in the aeration tank is preferably maintained at 34 mg/L. In order to ensure a satisfactory supply of oxygen, it is necessary to end with a managed aerator.www.khnwatertreatment.com
