Paint manufacturing process has several unfavorable aspects to the environment in Turkey. One of these impacts is wastewater treatment. Paint wastewater contains huge amounts of toxic chemical substances, bio refractory compounds, pigments and microorganisms. So, advanced treatment requirement is available to dispose of colour, microorganisms and chemical oxygen demand (COD). The high organic content of wastewater causes serious environmental challenges and contamination for the living organisms and the ecosystem in the receiver media unless it is treated adequately. In this context, the treatment process to be implemented should be preferred in such a way as to give the least damage to the environment. In this study, three treatment scenarios that contain electrocoagulation (Scenario-1), Fenton process (Scenario-2) and membrane distillation (Scenario-3) have been created for wastewater treatment facility of a paint industry in Turkey. For three scenarios, environmental impact assessment has been carried out with Fine-Kinney method. It is aimed to choose best environmental technology before investment. The evaluation results revealed that Scenario-2 has the less environmental impacts that total impact value is 556. Scenario-1 has the highest total impact value as 756, relatively. Total impact value related to Scenario-3 is 637. According to the evaluation results, Fenton process is the best environmental-friendly treatment technology for wastewater treatment of a paint industry in Turkey.
