Today, water resources conservation is considered as the most vital human resource by various international communities. The water stream is mainly contaminated by the various applications. Due to the low efficiency and issues of conventional treatment methods, newer methods of treatment of industrial wastewater are being introduced. One of the new methods is the use of peroxidase enzymes in the treatment of industrial and urban wastewater. In this paper, four different peroxidase enzymes have been studied to remove BTEX compounds (Benzene, Toluene, Ethylbenzene, and Xylene) in wastewater effluent. The best peroxidase enzymes have been chosen to decrease BTEX compounds after evaluating the four enzymes via the hierarchical analysis process (AHP). The cost, efficiency, environmental requirements, and industrialization have been selected as criteria in the AHP method. Also, peroxidase from mustard, peroxidase from horseradish, peroxidase from lignin and oxidase from polyphenol were proposed for this study. Expert choice software has been applied to evaluate the AHP process. The analyze of various criteria indicated that the cost parameter with 31.3% preference was chosen as the main criteria, as well as the oxidase from polyphenol was selected as the proposed alternative with 28.1% of priority.
