Integrated water resource management model for process industry in Lithuania

Water resource management has become an important operational and environmental issue. The increasing costs of dependable water supplies and wastewater disposal have increased the economic incentive for implementing technologies that are more environmentally friendly, and that can ensure efficient use of natural resources. A structured “integrated water resources management,” (IWRM) model for water management is presented as a useful tool for research into complex water using production systems in industrial companies. The step-by-step procedure and the consistent relationships between the diagram types allow straightforward implementation of water saving projects. By performing various case studies, it became clear that the IWRM model is applicable to various types of water using industrial companies. Therefore, wastewater reclamation and reuse are effective procedures for more sustainable industrial development programs.
