Tertiary nitrifying trickling filters (NTFs) at the Littleton/Englewoo
d wastewater treatment plant provide for nitrification to meet seasona
lly varying effluent requirements for ammonia nitrogen. Operation of t
he full-scale facilities during the past two years demonstrates highly
efficient oxidation of ammonia and the effectiveness of biofilm contr
ol strategies. A decline in nitrification performance caused by predat
ors was successfully corrected by the use of a special alkaline backwa
sh feature which controlled the level of larval development within the
NTFs. (C) 1997 IAWQ. Published by Elsevier Science Ltd.
