determination of water pollution damage caused by desalinators in the south pars special zone (case study: noor vijeh disalinator)

the present study aimed at investigating and estimating the amount of damage caused by waste water pollution of water desalinators in the south pars special zone. the main reasons for conducting this study were to investigate the creation of environmental pollutants as a result of the development and expansion of different industries in the south pars zone, as well as the ecological sensitivity of this zone. in recent years, the use of reverse osmosis water filteration system (ro) has increased, this is due to the lack of water supplies in some regions of the country and the industrial consumption. this study aimed to investigate, estimate, and analyze the amount of environmental damage caused by the noor vijeh water desalinator in the south pars special zone, as well as determining effective variables on the usage of water desalinators in creating polluting of water ecosystem. additionally, the damage caused by waste water pollutants of the aforementioned desalinator was estimated through damage assessment and estimation of external costs. to this end, samples of waste water from the noor vijeh water desalinator were collected in two seasons. various physical and chemical parameters of the water (such as ph, tds, sulfate, sodium, calcium, iron, mercury, and manganese) were tested. the results and their comparison with the national standards indices, required for discharging into the persian gulf (institute of standards & industrial research of iran) indicated that the density of tds, sulfate, sodium parameters in both seasons were above the standard limits.
