How the Process Works

The Extended Aeration Process, a modification of the Activated Sludge Process, effectively treats the contaminants in wastewaters. The standard basis of design includes an aeration system, providing a 24-hour detention time, and a final settling tank, with an effective 4-hour detention time.

Diffused air is introduced into the aeration tank. This provides the proper environment for the development of aerobic bacteria. These bacteria thrive on the materials contained in the wastewater. The prolonged period of aeration, in addition, oxidizes a portion of the solids in the system. Oxygenation by diffused aeration provides operating flexibility and standby reserve to meet the demanding requirements of the varied package plant applications.

Separation of the solids from the mixed liquor developed in the aeration tank takes place in the settling compartment. The clarified effluent is withdrawn for reuse or discharged into a receiving stream from the top of the settling tank. The settled solids are rapidly pumped from the bottom of the settling tank back to the aeration system. These Extended Aeration Plants are proven workhorses, providing excellent Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS) removal efficiencies. Only minimal routine housekeeping and operational tasks are required of the plant operator.
