A novel, economical, efficient and versatile lagoon aeration system is provided which can be used with existing or new wastewater (sewage) lagoons to increase the lagoons treatment efficiency and capacity, and to allow for a continuous, year round discharge of treated wastewater to environment. The system can be operated in warm and cold climates for treatment of municipal and industrial wastewaters of varying strength and flow rates in a secondary activated sludge treatment process or in a tertiary activated sludge treatment process, or an extended aeration treatment process. The system employs patented (Patent No: U.S. Pat. No. 6,969,052 B2) Air Aspirator-Mixer (AAM) which provides highly efficient wastewater aeration outside the lagoon which facilitates an easy and economical operation and maintenance of the system throughout the year.
