Case Study: Strathmore WWTP

The Strathmore WWTP was constructed to replace eight extended aeration lagoons. The plant was designed to process 4,000 m3/day (1 MGPD) Average Day Flow, 10,000 m3/day (2.6 MGPD) Peak Day Flow and the permit stipulated effluent of less than 20 mg/l BOD and TSS, less than 5/10 mg/l N-NH3 in summer/winter respectively, less than 1 mg/l Total Phosphorus and less than 200 MPN/100 ml fecal coliform. The plant features included headworks, two USBF bioreactors, alum storage and dosing and a UV disinfection system. Alum solution (49%) was dosed into the anoxic compartment of the bioreactors. Phosphorus precipitation and coagulation took place within the bioreactor internal circulation. Filtration was solely by the USBF clarifiers - the process did not include effluent post-filtration.
