Abstract The Upper Thompson Sanitation District (UTSD) advanced wastewater treatment facility, located in Estes Park, Colorado, incorporated several unique unit processes. Among these were flow equalizaton, attached growth nitrification, mixed media filtration and ozone disinfection. Plant design flow was 5,680 cu m/day (1.5 mgd to 1.0 mgd). The activated sludge, nitrification and filtration processes have two parallel trains. By selectively using one half of the available units design flow conditions were achieved at one-half the plant design flow rate. Overall plant performance in terms of BOD5 and TSS removal was consistent, averaging 95 percent and 96 percent, respectively. Ammonia oxidaton was not as consistent, due to loading extremes and cold weather operationg conditions. Performance characteristics of two nitrification tower media types (plastic dumped and redwood slats) were different.
