MANAGEMENT OF INDUSTRIAL WASTWATER USING INTERNAL WATER RECYCLES Hassan I Mohamed(1) and Sameh S. Ahmed (2) (1) Associate Prof. of Hydrology (2) Associate Prof. of Mining and Environmental Engineering Civil Engineering department ALMajmaa’h Engineering College King Saud University [email protected] Abstract Management of water resources became one of the omnipresent problems that spared worldwide. In the last few decades industrial water uses increased in developing countries along with industrial diversification. Thus, the limitation of water resources could obstruct the stainable development in these countries. This has imposed a real challenge on the scientists to introduce a new techniques and methods for water conservation. The huge loss of water during the industrial cycles needs reconsiderations for better management by minimizing the wastewater which could be achieved if reused economically. Some industries such as sugar require a high amount of water, for example, the production of 1 ton sugar needs 70 to 120 m3 of water. Introducing internal water cycles can meet the demand of water for bigger factories. In this paper, an intensive review of the new techniques for water conservation and waste prevention will be highlighted and discussed. An approach for water management in industry is presented. The approach is performed on various case studies. The study showed that wastewater reclamation and reuse are effective procedure for more sustainable industrial development programs.
