Abstract: In this research, the effect of operating variables, namely, inlet isoprene (1–4  g/m3) and acetone concentrations (0.25–1  g/m3), flow rates (0.0785–0.157  m3/h), and biofilter heights (25, 50, 75, and 100 cm) on the ...

Abstract: Biosorption of mercury ions from aqueous solution using activated sludge was investigated through parametric experiments. The influence of process variables like initial solution pH, adsorbent dose, initial mercury ...
