WebMay 1, 1998 · The standard oxygen transfer rate (SOTR, g/m3 · s) is shown to be related to EI through a second-degree equation: SOTR = −11.5 EI2 + 2.27 EI (r2 = 0.951). The model … WebIf the pond temperature is 77°F (25°C) and the dissolved oxygen level is 5 Parts Per Million (PPM) or 5 mg/l, an aerator system or diffuser that is rated at 3 pounds of oxygen per hour will really only provide 35% of the advertised SOTR or around 1.05 pounds of oxygen per hour (3 lbs x 35 percent = 1.05 lbs).

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).
