Ecological Engineering

During winter, when daily mean outside air temperature was as low as −20 °C, a relatively low water temperature in the range of 5.1 8 °C in the effluent and a low MTBE and benzene mean removal rate of 0.41 ± 0.07 and 2.08 ± 0.33 g m−2 d−1, respectively, was observed at a low HLR (120 L m−2 d−1).

Ecological Engineering

The performance comparison of three OCBs, which were composed of rice straw (RS), pine sawdust (PD), and activated carbon with <1 mm quartz sand (AC), indicated that the RS OCBs produced the highest mean removal rate of 73% for ammonium-N (NH4+ N) and 96% for nitrate-N (NO3− N).

Journal of Hydrology

Accordingly, the mean removal rate probably does relax, but the data that were available to this study are too aggregated to make this inference conclusively.

Plosone

For instance, mean removal rate for nitrate is 101 mg N m−2 d−1, but values higher than 400 mg N/m d were obtained when input concentrations were about 7 mg NO3-N/L.
