Abstract
In recent years, cultures of algae were developed for both wastewater treatment and bio-fuel
production. In this research, green microalgae Chlorella vulgaris were applied for bioremediation of an Iranian
petrochemical wastewater samples. The efficiency of C. vulgaris and nonionic surfactants were examined in
laboratory scale for elimination of COD, BOD, Total Nitrogen (TN), Total Phosphors (TP), and total petroleum
hydrocarbons (TPH). In the preliminary study, the growth of the algae were monitored in pure as well as 25%,
50% and 75% diluted wastewater samples The effectiveness of two surfactants of Tween 20 and Tween 60
were investigated in 15 day experiments. Removal of all parameters was significantly increased using surfactants.
Nitrogen and Phosphors removal were observed in all experiment up to 100%. Maximum TPH degradation of
27% was observed by Tween 60 compare to 10% for control sample. Hence, using Chlorella vulgaris and
surfactants can be recommended for treatment of wastewaters from petroleum industries.
