Abstract:

 In developing countries, conventional physico-chemical methods are commonly used for removing contaminants. These methods are not efficient and very costly. However, new in site strategy with high treatment efficiency and low operation cost named constructed wetland (CW) has been set. In this study, Phragmites australis was used with free surface batch system to estimate its ability to remediate total petroleum hydrocarbons (TPH) and chemical oxygen demand (COD) from Al-Daura refinery wastewater. The system operated in semi-batch, thus, new wastewater was weekly added to the plant for 42 days. The results showed high removal percentages (98%) of TPH and (62.3%) for COD. Additionally, Phragmites australis biomass increased significantly during experiment period with 60% increasing in wet weight. These results proved the ability of Phragmites australis to tolerance in contaminant environment and enhanced biodegradation of TPH. Two kinetic models were used, and pseudo-second order was fitted to data with R2 of 0.999.
