Abstract:The effect of wastewater temperature on the rate of nitrification was studied in two pure-oxygen moving-bed biofilm reactors, fed on secondary effluent from a municipal wastewater treatment plant. The first Reactor (R1) was operated under ammonia-limiting conditions, while the second Reactor (R2) was operated under oxygen-limiting conditions. Quite surprisingly, the former showed a negligible influence of thermal changes on nitrification rates, while the latter showed a much higher dependence. In this paper, a…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
