Abstract—This study presents the results of an analysis of the
most common Volatile Organic Compounds (VOCs) in
wastewater samples from one of the largest wastewater
treatment plants in Kuwait. Samples from four different
locations (plant influent, aeration tank inlet, aeration tank, and
plant effluent) were collected weekly and were analyzed for
toluene, benzene, xylene, 1, 3, 5 trimethylbenzene,
dichloromethane and chloroform. The results showed that all
the selected VOCs were detected except benzene. The average
concentrations of VOCs that entered the treatment plant were
as follows: chloroform 0.22 ± 0.03 μg/mL, dichloromethane 0.18
± 0.05 μg/mL, toluene 0.08 ± 0.01 μg/mL, O-Xylene 0.03 μg/mL,
M-Xylene 0.01 μg/mL, P-Xylene 0.02 μg/ml, and
1,3,5-trimethylbenzene 0.02 μg/mL. The concentration of VOCs
during the treatment processes decreased for all the selected
VOCs (treatment efficiency >98%), except chloroform, which
has increased. The disinfection process in the treatment plant
might have generated byproducts (such as chloroform) which
could have increased chloroform concentration. In conclusion,
all of the analyzed VOCs in this study were lower than the
maximum level of VOCs in treated wastewater.
Index Terms—Benzene, cancer, wastewater treatment plant.
