Reuse rate of treated wastewater in water Reuse system
Journal of environmental sciences (China), 2005Co-Authors: Yao-bo Fan, Wen-bo Yang, Yuan-song WeiAbstract:A water quality model for water Reuse was made by mathematics induction. The relationship among the Reuse rate of treated wastewater(R), pollutant concentration of Reused water( Cs ), pollutant concentration of influent( C0 ), removal efficiency of pollutant in wastewater(E), and the standard of Reuse water were discussed in this study. According to the experiment result of a toilet wastewater treatment and Reuse with membrane bioreactors, R would be set at less than 40%, on which all the concerned parameters could meet with the Reuse water standards. To raise R of Reuse water in the toilet, an important way was to improve color removal of the wastewater.

industrial symbiosis and waste recovery in an indian industrial area
Resources Conservation and Recycling, 2010Co-Authors: Ariana Bain, Megha Shenoy, Weslynne Ashton, Marian ChertowAbstract:Recovery, Reuse and recycling of industrial residuals, often dismissed as wastes, are common in India and other industrializing countries largely due to lower associated costs. Some wastes are Reused within the facility where they are generated, others are Reused directly by nearby industrial facilities, and some are recycled via the formal and informal recycling markets. Direct inter-firm Reuse is the cornerstone of the phenomenon termed industrial symbiosis, where firms cooperate in the exchange of material and energy resources. This study applies material flow analysis to an economically diverse industrial area in South India to characterize the recovery, Reuse and recycling of industrial residuals. It quantifies the generation of waste materials from 42 companies as well as the materials that are directly traded across facilities and those that are recycled or disposed. This study encompasses a business cluster in Mysore in the State of Karnataka, and is the first in India to thoroughly quantify material flows to identify existing symbiotic connections in an industrial area. Examined industries in this industrial area generate 897,210 metric tons of waste residuals annually, and recovered 99.5% of these, 81% with Reused by the companies that generated them, with one company, a sugar refinery, processing most of this amount. Geographic data show that operations within 20 km of the industrial area receive over 90% of residuals exiting facility gates. Two-thirds of this amount goes directly to other economic actors for Reuse. This study makes key contributions to the literature in distinguishing how particular types of materials are Reused in different ways, the geographic extent of symbiotic activities and the important role of the informal sector in industrial waste management in industrializing regions.

Winter Simulation Conference - Reusing simulation components: simulation software and model Reuse: a polemic
2002Co-Authors: Michael PiddAbstract:Is it really true that simulation models and simulation software should always be regarded as candidates for Reuse, or is it better to be selective? What are the obstacles to simulation software and model Reuse? Can these be surmounted and, if so, at what cost? There is a range of levels at which simulation software may be Reused, a range of costs to be borne and range of benefits that may be achieved. It is crucial to consider the issue of validity when considering model Reuse and this needs to be a fundamental part of any Reuse strategy. There may be circumstances in which Reuse is economic, especially when a small, low-fidelity model will suffice.

toward a theory of knowledge Reuse types of knowledge Reuse situations and factors in Reuse success
Journal of Management Information Systems, 2001Co-Authors: Lynne M MarkusAbstract:This paper represents a step toward a theory of knowledge reusability with emphasis on knowledge management systems and repositories, often called organizational memory systems. Synthesis of evidence from a wide variety of sources suggests four distinct types of knowledge Reuse situations according to the knowledge Reuser and the purpose of knowledge Reuse. The types involve shared work producers, who produce knowledge they later Reuse; shared work practitioners, who Reuse each other's knowledge contributions; expertise-seeking novices; and secondary knowledge miners. Each type of knowledge Reuser has different requirements for knowledge repositories. Owing to how repositories are created, Reusers'requirements often remain unmet. Repositories often require considerable rework to be useful for new Reusers, but knowledge producers rarely have the resources and incentives to do a good job of repurposing knowledge. Solutions include careful use of incentives and human and technical intermediaries.
