Abstract

The increasing pollution from urban and industrial wastewaters with toxic metal ions is an issue of environmental concern. This study investigated the efficacy of continuous aeration process for the removal of heavy chromium metal. This study is an experimental study in which the variables of initial concentration of Cr (0.3, 1, 1.5 mg/l), hydraulic retention time (2, 4, 6, 8 h) and input BOD5 concentration (100,150,200) mg/l of chromium was investigated in removal efficiency for continuous aeration reactor. The results showed that the chromium removal efficiency was 98.21 percent in 0.3 initial concentration, hydraulic retention time of 8 h and input BOD 5 200 mg. This study showed that the use of continuous aeration reactor has a high efficiency for the removal of chromium.
