This paper summarises the performance of three biological nutrient removal sewage treatment plants in Queensland (Australia), These plants are "extended aeration" types, treating screened, degritted raw sewage using a configuration similar to the "3-Stage Phoredox" concept but including an oxidation ditch as the anoxic/aerobic reactor. A summary of the design loads and other plant parameters is provided, along with summary plant effluent data over a period of up to six years. The results show that these plants achieved excellent nutrient removal performance (geometric mean total N < 3 mgN/L and total P < 2 mgP/L achieved), through a combination of biological and simultaneous chemical removal using alum, despite the lack of filters on the secondary effluent. Effluent suspended solids were typically <3 mg/L and BOD5 < 4 mg/L. The capital cost for these plants was found to be below the average trend for BNR plants in Australia when compared on a similar basis (population equivalent and effluent quality), whilst the power input per unit organic load removed was in the upper quartile for a range of BNR plants.
