Project Summary Sludge in the city in Illinois Pond # 1 was taking up valuable treatment capacity and causing odors. Sludge had accumulated to the point where part of the sludge blanket was exposed to the surface allowing odors to escape. State regulators were also demanding improvements because BOD5 test results were too high. Situation Sludge accumulation creates several different problems for lagoon operators. About 2 mg/l of oxygen should be maintained over a sludge blanket to ensure odor free operations. If sludge is exposed to the atmosphere, odors are free to escape. In addition to causing odor problems, a sludge blanket can also exert a substantial oxygen demand as it releases ammonia, organic acids, and other anaerobically gener- ated by-products back to the water column. This phenomenon is respon- sible for recurring algae blooms causing TSS problems and elevated BOD5's. FIELD REPORT City in Illinois Profile Location: Illinois Service Population: 3,300 Number of Lagoons: 2 Flow: 700,000 gpd Solution In May, the city decided to solve these problems by desludging their lagoons with BIO ENERGIZER ® . After 14 months of BIO ENERGIZER ® treatment, 70% of the sludge blanket was removed. The city's Wastewater Superintendent had this to say about BIO ENERGIZER'S performance: "Prior to using BIO ENERGIZER ® half my lagoon capacity was lost to sludge. Sludge depth averaged 41 inches. After using BIO ENERGIZER ® my average sludge depth dropped to 12 inches. Not only did it cost about 1/10th the cost of dredging, it also satisfied the local I.E.P.A. I highly recommend this product to anyone."
