Description:
The wastewater lagoons at Eudora, Kansas, consist of three cells in series and were placed into operation in May, 1972. These lagoons were designed for a population of 4000. Currently, the sewered population of Eudora is 2200. The lagoons were studied in detail from September, 1974, through August, 1975. Analyses were made twice weekly for 8 months and daily for 4 months. The results indicated the raw wastewater characteristics were normal for a small residential community. The wastewater lagoons produced typical results with temperature having the greatest impact on the microbiology and their biochemical reactions. The effluent quality from the treatment system was determined primarily by the growth and suspension of the algae. While the effluent BOD5 generally met the 30 mg/l effluent criteria, the effluent suspended solids concentrations far exceeded the 30 mg/l criteria. Removal of the effluent suspended solids would produce a well treated effluent with a high degree of removal of nitrogen and phosphorus as well as BOD5.
