The extended aeration activated sludge process is made use of in places where the influent reception rate in the wastewater treatment plant is below 50,000 gpd or 2 L/s. Some of the advantages of the extended aeration process are: This process requires little time for preparing the site as the plants are manufactured as pre-engineered and packaged units. This process proves reliable under

Comparison of the efficiency of extended aeration

Also, in the extended aeration activated sludge in Paveh, these mean removal efficiencies were 97.5–100% and 100%, respectively. The results indicated that the efficiency of the stabilization pond system was more honorable than the extended aeration activated sludge system. Moreover, the efficiency of all three WTPs was desirable. Thereafter, the effluent quality of all three WTPs was

Extended Aeration System Water Treatment Waste

Extended aeration systems have a relatively low sludge yield due to long sludge ages, can be designed to provide nitrification, and do not require a primary clarifier. . Disadvantages of extended aeration system: Extended aeration plants do not achieve denitrification or phosphorus removal without additional unit processes.
