Abstract [en]

Pollution of the drinking water environment has long been thought to be a primary cause of diseases. According to environmental research, there is a global water quality crisis. From an environmental stand point, eutrophication or accumulation of nitrates in wastewater are expected to cause high ammonium, low pH and increased nitrate concentrations [Koren et al. 2000] which are a critical form of nitrogen that needs our attention. This study considers the case of eutrophication in south-west Iran. This region is located in the Khuzestan province and consists of two basins (Karun and Dez) which can be seen as susceptible to the effect of eutrophication. This paper analyses the environmental pollution impact, economic, and social approaches of two waste water treatment plants. The case study focuses on a waste water treatment plant operated by activated sludge in Iran and the reference study is technology combined Sharon-Anammox treatment in Netherlands. The environmental impact assessment of these Waste Water Treatment Plants (WWTPs) has been analyzed by a Triple Bottom Line method. The hypothesis is to prove a general and specific outlook of the lowest environmental emissions, the lowest costs and creation of better welfare. The other method applied in this study is the barriers of transferring technology. The results show that the combined Sharon-Anammox method is able to significantly reduce the environmental impact based on the methods applied in this study.In this study, the generally considered barriers are problems of methods of transferring combined Sharon-Anammox technology to Iran and the possible obstacles that may be encountered in the transfer of technology to Iran. The result of this study is estimated with respect to an evaluation of political, environmental, economic, social, and technological capacity. The result is that most potential problems are political and economic in nature, which may be because these two issues are so closely related to each other. In this case, lack of management is a problem in the institution of policy, and could affect the economic situation. In fact each of the barriers could be overlapped and affect each other. Regarding all barriers and problems that are in the process of transferring technology, Iran as a developing country would be able to receive technologies.
