WebFeb 24, 2005 · The combination of aerobic and anaerobic ammonium oxidizing activity results in almost complete nitrogen removal (87%), using 63% less oxygen and 100% less reducing agent than in conventional processes [ 5, 24] (Equation 1). Webfactor. The alpha factor is the ratio of oxygen mass transfer rate in process water to that in clean water. The alpha factor represents the reduction in oxygen transfer rate due to surfactants in the influent wastewater. In general, the alpha factor, and thus the OTE, increases with longer mean cell retention times (MCRT) (Rosso et al., 2006a).
