Trickling filter nitrification
WebJan 1, 2000 · The nitrification rates measured in aquaculture lie under the values found in municipal wastewater, and this is probably a result of the low TAN concentrations inhibiting nitrification. Also, trickling filters normally show lower nitrification rates than other biofilters (Speece, 1973, Wortman and Wheaton, 1991). WebThe aerobic phase follows the anaerobic phase in which the wastewater in the trickling filter is emptied into the storage tank. In this phase, the trickling filter sump is constantly …
