Introduction: Due to population growth and subsequent limited water resources, the use of treatment plant effluents is of particular importance. Therefore, this study was conducted to identify the environmental effects of the treatment plant and also to identify critical points or weaknesses of the treatment plant system and provide corrective action to reduce the severity of the effects.
Methods: After visiting the research institute and collecting data (during the years 2017-2018), the energy, consuming materials and output of the system were calculated using the life cycle assessment method. Finally, information on the spread of pollution and consumption was included in the list of index effects. To analyze the obtained information, Simapro software (using ILCD 2011 Midpoint V1.03 method) version was applied.
Results: Based on the research findings, the software depicted the evaluation of the effects in 13 categories and all the information entered in the software according to the impact, has participated in each category of effects, the most effective factors related to chloride, energy consumption and oil.
Conclusion: The results of this study show that the main critical point identified in the treatment plant is related to electricity and the sanitary effluent is in a worse condition than the industrial effluent. However, the environmental impact of industrial effluents should not be neglected. Due to the fact that the MBR (Memberane Bio Reactor) method is considered as one of the best methods of wastewater treatment, it is not recommended to change the treatment method, but with continuous monitoring and management of the system, it is possible to reduce the consumption of raw materials.
