Abstract

Tehran as the capital and biggest city of Iran has so many attractions which have resulted in problems such as industries centralization and increasing population in and around the city. Therefore water demean has become ever increasing. It is important to notice that discharging untreated domestic and INDUSTRIAL WASTEWATER of the city into the groundwater has resulted in much pollution and raising level. On the other hand, and in recent years there was decreasing rainfall and so water shortage has been obvious. Therefore, it seems an essential task to reuse and or recycle water in present industries. For this study and among the established industries in Tehran area, factories having fifty or more workers of textile, tannery, pulp and paper industries have been chosen, as the test society. Most of the tanneries were transferred from Tehran city to the outside and about 14.5% of total remained industries are related to textile, Pulp and paper manufacturing in the first phase of this study. The qualitative and quantitative characteristics of water used in these factories and possibilities for water recoiling have been investigated. The results of study showed that the most consumption is related to textile industry. Water needed for all chosen industries is brought about from tap water (11%), tap water and deep weels (11%) and deep weels (78%) chosen industries which water utilized in industry, supply from city water 11% city water and well 11% and only well 78%. The amount of wastewater produced by textile Wood pulp and paper and trainees water industries in Tehran area is about 21500m3 and considering 200 liters per capital wastewater production, it is equivalent to 107500 persons wastewater production. Among textile Wood Pulp and paper and tannery industries, the most wastewater production is related to textile industry with about 87% of total wastewater production.
