Abstract [en]

This paper describes the findings of a long term study of the nitrification performance of apurpose built, large-scale, pilot plant consisting of two mirrored, aerated, continuouslyoperated upflow filters (ACoUFs) operating under realistic conditions. The effect oftemperature, liquid flow rate, aeration rate and media types on the performance of each ofthese filters is reported. After a start-up period of 2-3 weeks each plant performed consistentlyand the performance, expressed as a concentration change between influent and effluent, wasfound to depend directly on temperature and aeration but inversely on flow rate, with littleinteraction between the variables. The introduction of these aerated CoUF variants can havea considerable role to play in increasing effluent quality.
