آلودگی آب در گیاهان تصفیه فاضلاب: یک تجزیه و تحلیل کارایی با خروجی نامطلوب

The obtained results are then used to identify the efficiency explanatory variables: among them, the facilities’ capacity, the percentage of wastewater discharged by the industrial and agricultural activities and the level of compliance with the pollutant concentration threshold set by the legislator have a significant impact on the WWTP performance. The integrated performance assessment allows the water authorities to combine the WWTP efficiency together with the environmental sustainability issue and it has the potential for further promising environmental inspections.
