Intermittently Decanted Extended Aeration Lagoon The Intermittently Decanted Extended Aeration Lagoon, or IDEAL, consists of an EDI floating lateral aeration system with Magnum fine bubble diffusers, two chains of BioReef BioCurtain, a static decanter with flow control valves, an overflow pipe with Storm Mode™, process controls, and a blower package. The simple operation of the IDEAL provides easy, cost-effective operation while the sophistication of the design provides high levels of BOD, TSS and ammonia removal. The process requires no active sludge management and extremely high flow events present no operational problem or concern from washout of the reactor. The IDEAL also provides up to 66% total nitrogen as part of the basic package, which means the owner is already prepared for future increases in nitrate or nitrogen requirements. The unique ability of the IDEAL to provide front-of-plant treatment provides several benefits over other lagoon-based technologies. First, the warmest water in the winter is found in the first cell. By performing treatment in the first cell the need for thermal covers is reduced. Second, by removing ammonia at the front of the plant the system can utilize the influent carbon for denitrification, which provides oxygen and alkalinity recovery while helping to meet future regulations without having to incorporate expensive future components. Lastly, because the sludge is retained in the first cell there is no need to operate and maintain sludge return pumps.
