Industrial effluent limitations should be established regarding the special characteristics of each sector withemphasis given to the local context, whereas, in Iran, a uniform“Wastewater Effluent Standard”is employedthroughout the country in which no specific industrial effluent limitations have been considered. This gaphighlights the essential need for a transparent and scientifically proven methodology for determining effluentemission limit values (ELVs) at the sector level. In this research, an integrated approach is proposed based on theapplication of the Best Practicable Control Technology Currently Available (BPT) concept. The modelling fra-mework includes a series of sequential steps comprising two main sections: 1. identifying the effluent emissiondatasets, and 2. computing the emission levels associated with the BPT (BPT-AELs). To identify the datasets, themethodology follows two different procedures: 1. a detailed analysis of the environmental performance of thissector in the country to determine the plants reflecting BPT, and 2. screening their emission datasets throughstatistical analysis. The Best Available Techniques (BAT) principle is employed as a reference element for de-termining the best representative plants, and the results indicate that corrective measures in accordance with theBAT considerations should be implemented in many of the plants under consideration. The comparison of thederived BPT-AELs with the existing standards show that they are mainly lower than the standard levels and arereasonable estimations for the involved parameters. Conclusively, this methodology presents a reliable andpractical stepwise process at the sector level, which can be developed for other industries.
